37f6130ec3 ARM: dts: BCM5301X: Make USB 3.0 PHY use MDIO PHY driver
Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which
requires register range "ccb-mii" <0x18003000 0x1000>. This range
overlaps with MDIO cmd and param registers (<0x18003000 0x8>).
Essentially, the platform driver partly acts like a MDIO bus driver,
hence to use of this register range.

In some Northstar devices like Linksys EA9500, secondary switch is
connected via external MDIO. The only way to access and configure the
external switch is via MDIO bus. When we enable the MDIO bus in it's
current state, the MDIO bus and any child buses fail to register because
of the register range overlap.

On Northstar, the USB 3.0 PHY is connected at address 0x10 on the
internal MDIO bus. This change moves the usb3_phy node and makes it a
child node of internal MDIO bus.

Thanks to Rafał Miłecki's commit af850e14a7 ("phy: bcm-ns-usb3: add
MDIO driver using proper bus layer") the same USB 3.0 platform driver
can now act as USB 3.0 PHY MDIO driver.

Tested on Linksys Panamera (EA9500)

6e1811900b ARM: tegra: Fix Tegra30 Cardhu PCA954x reset
On all versions of Tegra30 Cardhu, the reset signal to the NXP PCA9546
I2C mux is connected to the Tegra GPIO BB0. Currently, this pin on the
Tegra is not configured as a GPIO but as a special-function IO (SFIO)
that is multiplexing the pin to an I2S controller. On exiting system
suspend, I2C commands sent to the PCA9546 are failing because there is
no ACK. Although it is not possible to see exactly what is happening
to the reset during suspend, by ensuring it is configured as a GPIO
and driven high, to de-assert the reset, the failures are no longer
seen.

Please note that this GPIO is also used to drive the reset signal
going to the camera connector on the board. However, given that there
is no camera support currently for Cardhu, this should not have any
impact.

e40c7f75c9 ARM: dts: omap4-droid4: Use software debounce for gpio-keys
The default value of 5ms will use GPIO hardware based debounce clocks
that will keep L4PER from idling consuming about extra 30mW.

Use a value of 10ms that is above the hardware debounce maximum of
7.95ms forcing software based debouncing.

This allows droid4 to enter PER retention during idle as long as UARTs
are idled and USB modules unloaded or unbound.

Note that there seems to be a pending issue with having droid 4 enter core
retention during idle where GPIO bank 1 needs to be reset late after init
for some reason to not block core retention. In addition to that, we are
also missing GPIO related PM runtime calls for omap4 that will be posted
separately.

731b409878 ARM: dts: Configure duovero for to allow core retention during idle
By reconfiguring few GPIOs in the dts file we can make duovero parlor
hit retention during idle:

1. Let's a larger debounce value for gpio-keys

This will then make gpio-keys use software debounce and the GPIO
debounce clock is not enabled.

2. Let's allow WLAN suspend for mwifiex

This can be done just by adding keep-power-in-suspend.

3. Let's reconfigure smsc911x driver to use GPIO edge interrupt

This will allow using NFSroot while the system idles, and the kernel
has quite a few dts files with "smsc,lan9115" compatible using edge
interrupts.

Then to have the system hit core retention during idle, the UARTs
needs to be idled and USB modules need to be unloaded or unbound.

572cf7d7b0 ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt
The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line:

"WLAN SDIO out-of-band interrupt line. Set to rising edge (active high)
by default."

And it seems this interrupt can be optionally configured to use falling
edge too since commit bd763482c8 ("wl18xx: wlan_irq: support platform
dependent interrupt types").

On omap4, if the wlcore interrupt is configured as level instead of edge,
L4PER will stop doing hardware based idling after ifconfig wlan0 down is
done and the WL_EN line is pulled down.

The symptoms show up with L4PER status registers no longer showing the
IDLEST bits as 2 but as 0 for all the active GPIO banks and for
L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in
the /sys/kernel/debug/pm_debug/count.

While there is also probably a GPIO related issue that needs to be
still fixed, this change gets us to the point where we can have L4PER
idling.

I'm guessing wlcore was at some point configured to use level interrupts
because of edge handling issues in gpio-omap. However, with the recent
fixes to gpio-omap the edge interrupts seem to be working just fine.

Let's change it for all omap boards with wlcore interrupt set as level.

Both ports on the dra7-evm and related boards can be used
as dual-role ports. Although we don't enable dual-role mode
for USB2 port let's add the necessary extcon bits to it.

Move the common portion of extcon_usb2 into dra7-evm-common.dtsi

484d578b71 ARM: dts: omap5: Add missing cooling device properties for CPUs
The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.

Fix other missing properties (clocks, supply, clock latency) as well to
make it all work.
