[PATCH RESEND 0/4] Small updates to Snow and Peach Pit/Pi DTS

[Javier Martinez Canillas]

Hello Kukjin,

This series adds some DTS snippets that were missing in the mainline
Snow and Peach Pit/Pi Device Trees but are present in the downstream
ChromeOS kernel.

The series is composed of the following patches:

Javier Martinez Canillas (4):
  ARM: dts: Add power and lid GPIO keys pinctrl for exynos5250-snow
  ARM: dts: Add lid GPIO key device node for Peach boards
  ARM: dts: Set Peach boards USB WebCam regulators to always on
  ARM: dts: Configure regulators for suspend on exynos Peach boards

Patch #1 adds some pinctrl lines for the GPIO keys in the Snow DTS.

Patch #2 adds a device node and pinctrl lines for the lid GPIO in
the Peach boards DTS.

Patch #3 sets the regulators that supply voltage to the USB WebCam
in Peach boards as always on.

Patch #4 configures the max77802 regulators on the Peach Pit and Pi
boards to be enabled or disabled during system suspend.

Best regards,
Javier

[PATCH RESEND 1/4] ARM: dts: Add power and lid GPIO keys pinctrl for exynos5250-snow

[Javier Martinez Canillas]

The Exynos5250 Snow Chromebook has GPIO keys for power and lid
so the SoC I/O pins have to be configured in external interrupt
mode. Currently, this is working without setting the pinctrl
lines but is better to set it explicitly instead of relying on
the previous state of the I/O pins.

The DTS snippets were taken from the downstream ChromeOS tree.

from the downstream ChromeOS 3.8 kernel tree.

[PATCH RESEND 3/4] ARM: dts: Set Peach boards USB WebCam regulators to always on

[Javier Martinez Canillas]

The Exynos5420 Peach Pit and Exynos5800 Peach Pi boards have a built-in
Silicon Motion USB UVC WebCam whose power supply is the tps65090 fet5
regulator. Since the camera uses the generic USB Video Class driver and
this does not grab a regulator, mark the regulator as always on so the
USB device is enumerated and usable.

[PATCH RESEND 4/4] ARM: dts: Configure regulators for suspend on exynos Peach boards

[Javier Martinez Canillas]

The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
supports changing the regulator operating mode during runtime
and when the system enters into sleep mode.

To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel

[PATCH RESEND 4/4] ARM: dts: Configure regulators for suspend on exynos Peach boards

[Javier Martinez Canillas]

The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
supports changing the regulator operating mode during runtime
and when the system enters into sleep mode.

To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel

Yeah, but I don't think I checked all of submitted patches including

I think, this setting should be same with exynos5250-spring but different.

from: arch/arm/boot/dts/exynos5250-spring.dts
491         power_key_irq: power-key-irq {
492                 samsung,pins = "gpx1-3";
493                 samsung,pin-function = <0>;
494                 samsung,pin-pud = <0>;
495                 samsung,pin-drv = <0>;
496         };

Hmm...0xf should be correct so need to fix the spring DT?

Yes, the same problem has exynos5250-snow.dts. This is less relevant now
after commit f6a8249f9e55 ("pinctrl: exynos: Lock GPIOs as interrupts
when used as EINTs") that moved the pinmux reconfiguration to
.irq_{request,release}_resources() preventing the pads to be reconfigured
as regulator input/output.

But still for correctness we should audit spring / snow and change to 0xf.

Best regards,
Javier
