Pull gpio updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v5.2 kernel cycle. A bit
later than usual because I was ironing out my own mistakes. I'm
holding some stuff back for the next kernel as a result, and this
should be a healthy and well tested batch.
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to be
handled consistently. Unsurprisingly, we enforce the lines to be
either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone does,
so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed. Such
nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs and
outputs at the same time and after improving the MMIO library we
handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM work
as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update"

Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.
The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.
Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.
Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found
in DT.
This simplifies driver probe path and particularly phy handling.

Indirect register access goes through a DCR bus bridge, which
allows only one outstanding transaction. And to make matters
worse, each TEMAC IP block contains two Ethernet interfaces, and
although they seem to have separate registers for indirect access,
they actually share the registers. Or to be more specific, MSW, LSW
and CTL registers are physically shared between Ethernet interfaces
in same TEMAC IP, with RDY register being (almost) specificic to
the Ethernet interface. The 0x10000 bit in RDY reflects combined
bus ready state though.
So we need to take care to synchronize not only within a single
device, but also between devices in same TEMAC IP.
This commit allows to do that with legacy platform devices.
For OF devices, the xlnx,compound parent of the temac node should be
used to find siblings, and setup a shared indirect_mutex between them.
I will leave this work to somebody else, as I don't have hardware to
test that. No regression is introduced by that, as before this commit
using two Ethernet interfaces in same TEMAC block is simply broken.

The current API for the wilco EC mailbox interface is bad.
It assumes that most messages sent to the EC follow a similar structure,
with a command byte in MBOX[0], followed by a junk byte, followed by
actual data. This doesn't happen in several cases, such as setting the
RTC time, using the raw debugfs interface, and reading or writing
properties such as the Peak Shift policy (this last to be submitted soon).
Similarly for the response message from the EC, the current interface
assumes that the first byte of data is always 0, and the second byte
is unused. However, in both setting and getting the RTC time, in the
debugfs interface, and for reading and writing properties, this isn't
true.
The current way to resolve this is to use WILCO_EC_FLAG_RAW* flags to
specify when and when not to skip these initial bytes in the sent and
received message. They are confusing and used so much that they are
normal, and not exceptions. In addition, the first byte of
response in the debugfs interface is still always skipped, which is
weird, since this raw interface should be giving the entire result.
Additionally, sent messages assume the first byte is a command, and so
struct wilco_ec_message contains the "command" field. In setting or
getting properties however, the first byte is not a command, and so this
field has to be filled with a byte that isn't actually a command. This
is again inconsistent.
wilco_ec_message contains a result field as well, copied from
wilco_ec_response->result. The message result field should be removed:
if the message fails, the cause is already logged, and the callers are
alerted. They will never care about the actual state of the result flag.
These flags and different cases make the wilco_ec_transfer() function,
used in wilco_ec_mailbox(), really gross, dealing with a bunch of
different cases. It's difficult to figure out what it is doing.
Finally, making these assumptions about the structure of a message make
it so that the messages do not correspond well with the specification
for the EC's mailbox interface. For instance, this interface
specification may say that MBOX[9] in the received message contains
some information, but the calling code needs to remember that the first
byte of response is always skipped, and because it didn't set the
RESPONSE_RAW flag, the next byte is also skipped, so this information
is actually contained within wilco_ec_message->response_data[7]. This
makes it difficult to maintain this code in the future.
To fix these problems this patch standardizes the mailbox interface by:
- Removing the WILCO_EC_FLAG_RAW* flags
- Removing the command and reserved_raw bytes from wilco_ec_request
- Removing the mbox0 byte from wilco_ec_response
- Simplifying wilco_ec_transfer() because of these changes
- Gives the callers of wilco_ec_mailbox() the responsibility of exactly
and consistently defining the structure of the mailbox request and
response
- Removing command and result from wilco_ec_message.
This results in the reduction of total code, and makes it much more
maintainable and understandable.

The GPIO block can enter idle independently of the CPU power management
calls via smart-idle. When the GPIO block enters idle, level detection
stops working due to clocks being shut off, and an alternative form of
edge detection is used. However, this needs the edge detection
registers set to mark the appropriate edges.
Arrange to configure the edge detection enables along with the level
detection to ensure that any transition to active interrupt state that
occurs while the block is idle is detected as a wake-up event.
Since we enable the edge detection when configuring the IRQ, both
omap2_gpio_enable_level_quirk() nor omap2_gpio_disable_level_quirk()
become redundant, which also means OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER
can be removed. This can be now done without regressions as patch
"gpio: gpio-omap: fix level interrupt idling" allows level interrupts
to idle on omap4 without a workaround.

Since commit 648e921888 ("clk: x86: Stop marking clocks as
CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are
unconditionally gated off. Unfortunately this will break systems where these
clocks are used for external purposes beyond the kernel's knowledge. Fix it
by implementing a system specific quirk to mark the necessary pmc_plt_clks as
critical.

Pull clk subsystem updates from Stephen Boyd:
"We have a fairly balanced mix of clk driver updates and clk framework
updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional()
API to get clks that may not always be populated and a way to devm
manage clkdev lookups registered by provider drivers. We also do some
refactoring to simplify the interface between clkdev and the common
clk framework so we can reuse the DT parsing and clk_get() path in
provider drivers in the future. This work will continue in the next
few cycles while we convert how providers specify clk parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk
driver that got support for the G12A SoC. It dominates with almost
half the overall diff, while the second largest part of the diff is in
the i.MX clk driver that gained support for imx8mm SoCs. After that,
we have the Actions Semiconductor and Qualcomm drivers rounding out
the big part of the dirstat because they both got new hardware support
for SoCs. The rest is just various updates and non-critical fixes for
existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
- The big change this time around is the irqchip handling in the
qualcomm pin controllers, closely coupled with the gpiochip. This
rework, in a classic fall-between-the-chairs fashion has been
sidestepped for too long.
The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
have been rewritten to use hierarchical irqchip. This creates the
base from which I intend to gradually pull support for hierarchical
irqchips into the gpiolib irqchip helpers to cut down on duplicate
code.
We have too many hacks in the kernel because people have been
working around the missing hierarchical irqchip for years, and once
it was there, noone understood it for a while. We are now slowly
adapting to using it.
This is why this pull requests include changes to MFD, SPMI,
IRQchip core and some ARM Device Trees pertaining to the Qualcomm
chip family. Since Qualcomm have so many chips and such large
deployments it is paramount that this platform gets this right, and
now it (hopefully) does.
- Core support for pull-up and pull-down configuration, also from the
device tree. When a simple GPIO chip supports an "off or on" pull-up
or pull-down resistor, we provide a way to set this up using
machine descriptors or device tree.
If more elaborate control of pull up/down (such as resistance shunt
setting) is required, drivers should be phased over to use pin
control. We do not yet provide a userspace ABI for this pull
up-down setting but I suspect the makers are going to ask for it
soon enough. PCA953x is the first user of this new API.
- The GPIO mockup driver has been revamped after some discussion
improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for both testing
and virtual prototyping, e.g. when you do not yet have a GPIO
expander to play with but really want to get something to develop
code around before hardware is available. It's neat. The blackbox
testing usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating flags.
- A new device core helper for devm_platform_ioremap_resource() is
funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum driver.
- Wakeup support for PCA953x.

Pull ARM SoC platform updates from Arnd Bergmann:
"The APM X-Gene platform is now maintained by folks from Ampere
computing that took over the product line a while ago, this gets
reflected in the MAINTAINERS file.
Cleanups continue on the older mach-davinci and mach-pxa platform, to
get them to be more like the modern ones. For pxa, we now remove the
Raumfeld platform code as it now works with device tree based booting.
i.MX adds a couple new features for the i.MX7ULP SoC
Mediatek gains support for a new SoC: MT7629 is a new wireless router
platform, following MT7623.
Aside from those, there are the usual minor cleanups and bugfixes
across several platforms"

On i.mx8mq, there are two sdma instances, and the common dma framework
will get a channel dynamically from any available sdma instance whether
it's the first sdma device or the second sdma device. Some IPs like
SAI only work with sdma2 not sdma1. To make sure the sdma channel is from
the correct sdma device, use the node pointer to match.

This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.
The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

This EC is an incompatible variant of the typical Chrome OS embedded
controller. It uses the same low-level communication and a similar
protocol with some significant differences. The EC firmware does
not support the same mailbox commands so it is not registered as a
cros_ec device type. This commit exports the wilco_ec_mailbox()
function so that other modules can use it to communicate with the EC.

The header containing the configuration structure for davinci cpufreq
driver lives in mach-davinci/include/mach/. This is fine for now but
if we want to make davinci part of the multi_v5 build, no code external
to mach-davinci should include machine-specific headers.
Move the configuration structure to include/linux/platform_data.
