gpio: merrifield: Introduce GPIO driver to support Merrifield

2016-07-22T13:30:41+00:00

Intel Merrifield platform has a special GPIO controller to
drive pads when they are muxed in corresponding mode.

Intel Merrifield GPIO IP is slightly different here and there
in comparison to the older Intel MID platforms. These differences
include in particular the shaked register offsets, specific
support of level triggered interrupts and wake capable sources,
as well as a pinctrl which is a separate IP.

Instead of uglifying existing driver I decide to provide a new
one slightly based on gpio-intel-mid.c. So, anyone can easily
compare what changes are happened to be here.

gpio: rename gpio-generic.c into gpio-mmio.c

2016-04-29T14:14:32+00:00

This patch renames the gpio-generic.c into gpio-mmio.c.
This is because currently the file only contains code
for a memory-mapped GPIO driver. There isn't any support
for ioports or other resource type.

gpio: add tps65218 gpio

2016-02-11T11:25:16+00:00

Driver for the GPIO block found in ti's tps65218 pmics.

The device has two GPIOs and one GPO pin which can be configured as follows:
GPIO1:
	-general-purpose, open-drain output controlled by GPO1 user bit and/or
	 sequencer
	-DDR3 reset input signal from SOC. Signal is either latched or
	 passed-trough to GPO2 pin. See below for details.
GPO2:
	-general-purpose output controlled by GPO2 user bit
	-DDR3 reset output signal. Signal is controlled by GPIO1 and PGOOD.
	 See below for details.
	-Output buffer can be configured as open-drain or push-pull.
GPIO3:
	-general-purpose, open-drain output controlled by GPO3 user bit and/or
	 sequencer
	-reset input-signal for DCDC1 and DCDC2.

The input configurations are not meant to be used by the user so the driver
only offers GPOs.

v2: Added request routine that evaluates the fw config flags and removed module
    owner
v3: Added .direction_input() routine, and took care of all Linus Walleij
suggestions (clamp to bool, use proper include)
