[PATCH 0/2] qt1070 & gpio_keys add pinctrl consumer

Hi,

	The following patch series add the pinctrl support to the follwing
	keybords:

	 - gpio_keys
	 - qt1070

	The pinctrl is optionnal as not everyone need it

	If no objection I'll apply them via at91 as I have a long patch series
	of pinctrl for at91

If no pinctrl available just report a warning as some architecture may not
need to do anything.

Test it on sam9x5ek board with qt1070. It works well.

We're having a discussion on the level of where to impose pinctrl.

Jean-Christophe, could you please check the thread
"Input: omap4-keypad: Add pinctrl support"
and tell us what you think is the best approach?

Yours,
Linus Walleij
