pinctrl: pinctrl-single: Add pinctrl-single,bits type of mux

2012-09-13T07:00:10+00:00

With pinctrl-single,bits it is possible to update just part of the register
within the pinctrl-single,function-mask area.
This is useful when one register configures mmore than one pin's mux.

pinctrl-single,bits takes three parameters:

pinctrl: pinctrl-single: Make sure we do not change bits outside of mask

2012-09-10T07:14:03+00:00

Use the pcs->fmask to make sure that the value is not changing (setting)
bits in areas where it should not.
To avoid situations like this:

pmx_dummy: pinmux@4a100040 {
	compatible = "pinctrl-single";
	reg = <0x4a100040 0x0196>;
	#address-cells = <1>;
	#size-cells = <0>;
	pinctrl-single,register-width = <16>;
	pinctrl-single,function-mask = <0x00ff>;
};

&pmx_dummy {
	pinctrl-names = "default";
	pinctrl-0 = <&board_pins>;

	board_pins: pinmux_board_pins {
		pinctrl-single,pins = <
			0x6c 0xf0f
			0x6e 0x10f
			0x70 0x23f
			0x72 0xa5f
		>;
	};
};

pinctrl: Add one-register-per-pin type device tree based pinctrl driver

2012-07-14T20:33:08+00:00

Add one-register-per-pin type device tree based pinctrl driver.

This driver has been tested on omap2+ series of processors,
where there is either an 8 or 16-bit padconf register for each pin.
Support for other similar pinmux controllers can be added.
