Changes to split plat-omap/devices.c into mach-omap1 and mach-omap2
except for the RNG driver that will be done later on.
As this depends on omap-devel-hwmod-data-for-v3.5 and causes merge
conflict with omap-fixes-non-critical-for-v3.5, this branch is based
on merge of the two.

Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.) To make it more clear what is
being detected, convert the names from 3517 to AM35xx.
This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

[tony@atomide.com: change to use soc_is_omap instead]
Signed-off-by: Tony Lindgren <tony@atomide.com>
Current OMAP code supports couple of clocksource options based
on compilation flag (CONFIG_OMAP_32K_TIMER). The 32KHz sync-timer
and a gptimer which can run on 32KHz or system clock (e.g 38.4 MHz).
So there can be 3 options -
1. 32KHz sync-timer
2. Sys_clock based (e.g 13/19.2/26/38.4 MHz) gptimer
3. 32KHz based gptimer.
The optional gptimer based clocksource was added so that it can
give the high precision than sync-timer, so expected usage was 2
and not 3.
Unfortunately option 2, clocksource doesn't meet the requirement of
free-running clock as per clocksource need. It stops in low power states
when sys_clock is cut. That makes gptimer based clocksource option
useless for OMAP2/3/4 devices with sys_clock as a clock input.
So, in order to use option 2, deeper idle state MUST be disabled.
Option 3 will still work but it is no better than 32K sync-timer
based clocksource.
We must support both sync timer and gptimer based clocksource as
some OMAP based derivative SoCs like AM33XX does not have the
sync timer.
Considering above, make sync-timer and gptimer clocksource runtime
selectable so that both OMAP and AMXXXX continue to use the same code.
And, in order to precisely configure/setup sched_clock for given
clocksource, decision has to be made early enough in boot sequence.
So, the solution is,
Use standard kernel parameter ("clocksource=") to override
default 32k_sync-timer, in addition to this, we also use hwmod database
lookup mechanism, through which at run-time we can identify availability
of 32k-sync timer on the device, else fall back to gptimer.
Also, moved low-level SoC specific init code to respective files,
(mach-omap1/timer32k.c and mach-omap2/timer.c)

Add in most of the remaining hwmods (IP block descriptions) for the
OMAP44xx family of SoCs. There still seem to be a few missing, such
as those for the MMU IP blocks, but this seems to cover the bulk of
the remainder.
Clean up various aspects of the OMAP hwmod code, which is the IP block
control code for OMAP SoCs. In particular, this series results in
a considerable diffstat savings by changing the way that IP block
interconnections are defined.
Add the SL2 interface IP block and interconnect data. The SL2 is related
to the IVA-HD subsystem.
Add IP block and interconnect data for the C2C ("Chip-to-chip")
interconnect. This can provide a direct system interconnect link to
other devices stacked on the OMAP package.
Add the ELM IP block and interconnect data. The ELM can be used
to locate errors in NAND flash connected to the GPMC.

Add support for direct IP block interconnect ("link") registration to
the hwmod code via a new function, omap_hwmod_register_links(). This
will replace direct registration of hwmods, and a subsequent patch
will remove omap_hwmod_register().
This change will allow a subsequent patch to remove the hwmod data
link arrays. This will reduce the size of the hwmod static data and
also make it easier to generate the data files. It will also make it
possible to share some of the struct omap_hwmod records across
multiple SoCs, since the link array pointers will be removed from the
struct omap_hwmod.
The downside is that boot time will increase. Minimizing boot time
was the reason why the link arrays were originally introduced.
Removing them will require extra computation during boot to allocate
memory and associate IP blocks with their interconnects. However,
since the current kernel development focus is on reducing the number
of lines in arch/arm/mach-omap2/, boot time impact is now seemingly
considered a lower priority.
This patch contains additional complexity to reduce the number of
memory allocations required for this change. This reduces the boot
time impact: total hwmod link registration time was ~ 2655
microseconds with a simple allocation strategy, but is now ~ 549
microseconds[1] with the approach taken by this patch.
1. Measured on a BeagleBoard 35xx @ 500MHz MPU/333 MHz CORE, average
of 7 samples. Total uncertainty is +/- 61 microseconds.

Extend the OCP_* register offsets in the struct
omap_hwmod_class_sysconfig to 32 bits. This is required to add the
OMAP4+ GPU hwmod, which uses OCP_* register offsets larger than 16
bits.
Another possible solution may be to simply add a single 16 bit offset
field in this structure, and to add code to factor that offset into
all OCP_* register accesses. This would save some memory, since
almost no modules need 32 bit offsets.

One of the OMAP4 links was missing OCP_USER flags, since it was only
used by the DSP initiator, and we did not have an OCP_USER_DSP flag.
Future patches will switch the hwmod code and data to register
interfaces, rather than hwmods, and it will be mandatory for all
interfaces to have at least one user bit set. This patch resolves the
issue by adding OCP_USER_DSP and marking the DSP-IVA interface
appropriately.

The timer integration code pokes around in hwmod data structures.
Those data structures are about to change. Define a function,
omap_hwmod_get_resource_byname(), for the timer integration code to
use instead.
The original patch has been changed to use struct resource by Tony's
request, although the caller of this function should not be a driver._
Platform drivers should get their data through the regular platform_*
functions; DT drivers through the appropriate of_* functions. This a
function is only for use by OMAP core code in arch/arm/*omap*.

The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
work. Previously, the driver was simply calling a symbol defined in
the OMAP platform code, but this is incorrect: drivers should be fully
decoupled from platform and architecture code.
So instead, modify the driver to call through a platform_data function
pointer instead. We skip any DT aspect, since OMAP1 is not scheduled
to be converted to DT in the near future.
This resolves the following sparse warning:
It also gets rid of a cpu_is_omap16xx() call in a driver.
In the long term, it probably makes sense to move the OCPI bus code to
somewhere under drivers/. This should avoid the whole platform_data/DT
issue with this function.

Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.
Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.
In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.
Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.

From Tony Lindgren:
"This contains the updated gpio_to_irq patches from Tarun, and a trivial
build fix from Govindraj to #include <asm/system_misc.h> in pm.c.
The DSI mux patch is the same."

ARM: OMAP: pm: fix compilation break
ARM: OMAP: Remove OMAP_GPIO_IRQ macro definition
drivers: input: Fix OMAP_GPIO_IRQ with gpio_to_irq() in ams_delta_serio_exit()
ARM: OMAP: boards: Fix OMAP_GPIO_IRQ usage with gpio_to_irq()
ARM: OMAP2+: Remove __init from DSI mux functions
Since all references to OMAP_GPIO_IRQ macro are replaced now
with gpio_to_irq(), this can be removed altogether.

Pull MMC updates from Chris Ball:
Core:
* Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices
that support Data Tag will provide increased throughput for metadata.
* Faster detection of card removal on I/O errors.
Drivers:
* dw_mmc now supports eMMC Power Off Notify, has PCI support, and
implements pre_req and post_req for asynchronous requests.
* omap_hsmmc now supports device tree.
* esdhc now has power management support.
* sdhci-tegra now supports Tegra30 devices.
* sdhci-spear now supports hibernation.

Pull GPIO changes for v3.4 from Grant Likely:
"Primarily gpio device driver changes with some minor side effects
under arch/arm and arch/x86. Also includes a few core changes such as
explicitly supporting (electrical) open source and open drain outputs
and some help for parsing gpio devicetree properties."
Fix up context conflict due to Laxman Dewangan adding sleep control for

Pull "ARM: driver specific updates" from Arnd Bergmann:
"These are all specific to some driver. They are typically the
platform side of a change in the drivers directory, such as adding a
new driver or extending the interface to the platform. In cases where
there is no maintainer for the driver, or the maintainer prefers to
have the platform changes in the same branch as the driver changes,
the patches to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.
The new export of tegra_chip_uid conflicts with other changes in
fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED
conflicts with the cleanup of the interrupt handling of that driver.

Pull "remoteproc/rpmsg: new subsystem" from Arnd Bergmann:
"This new subsystem provides a common way to talk to secondary
processors on an SoC, e.g. a DSP, GPU or service processor, using
virtio as the transport. In the long run, it should replace a few
dozen vendor specific ways to do the same thing, which all never made
it into the upstream kernel. There is a broad agreement that rpmsg is
the way to go here and several vendors have started working on
replacing their own subsystems.
Two branches each add one virtio protocol number. Fortunately the
numbers were agreed upon in advance, so there are only context
changes.

"These changes are all specific to one board only. We're trying to
keep the number of board files low, but generally board level updates
are ok on platforms that are working on moving towards DT based
probing, which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal
of ams_delta_config and the addition of a lot of other data. The
Kconfig file has two changes in the same line, and in exynos, the
power domain cleanup conflicts with the addition of the image sensor
