[PATCH 00/10] ARM: dts: AM33XX: Add device tree data

[PATCH 00/10] ARM: dts: AM33XX: Add device tree data

[AnilKumar Ch]

Add device tree date for GPIO based various drivers matrix keypad,
volume keys, push buttons and use leds accross three AM33XX devices
viz EVM, BeagleBone and Starter Kit.

To make it functional this series also adds pinctrl data for all
the GPIOs used by various drivers. In this series only default state
pinmux/conf settings are added because of sleep/idle state pinctrl
values are not available.

These patches are based on linux-omap-dt:for_3.8/dts tree and these
were tested on am33xx devices according to added functionality.

[PATCH 01/10] ARM: dts: AM33XX: Add pinmux configuration for matrix keypad to EVM

[AnilKumar Ch]

Add pinmux configurations for gpio matrix keypad. In this patch, only
single named mode/state is added and these pins are configured during
pinctrl driver initialization.

Default mode is nothing but the values required for the module during
active state. With this configurations module is functional as
expected.

[PATCH 07/10] ARM: dts: AM33XX: Add pinmux configuration for gpio-leds to EVMSK

[AnilKumar Ch]

Add pinmux configurations for gpio based volume keys to am335x-evmsk.
In this patch, only single named mode/state is added and these pins
are configured during pinctrl driver initialization.

Default mode is nothing but the values required for the module during
active state. With this configurations module is functional as
expected.

Mmm, this 2 patches do have dependency on some driver changes that might
not be accepted for 3.8. And in fact I do have some comment on the RTC
one :-)
Don't you prefer to change the order to allow me to pull these ones first?
