[PATCH v4 4/9] ARM: dts: support pinctrl single in pxa910

[Tony Lindgren]

Hi,

To clarify my binding change comment for the generic pinconf
support, here's an example.

We need to move pinctrl-single pinconf properties here for
each pin group:

					pinctrl-single,bias-pull-down = <0xa000>;
					pinctrl-single,bias-pull-up = <0xc000>;

And then..

..remove these from here. Otherwise pinctrl-single,bits type controllers
won't be able to use the pinconf functions as we can have multiple pins
supported in a single register.
