gpio: drop owner assignment from platform_drivers

2014-10-20T14:20:31+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

gpio: ich: Add support for Intel Avoton

2014-03-19T08:58:23+00:00

This patch adds support for Atom C2000 series (Avoton and Rangeley). And has
the following options:
  - New addresses register.
  - Caching output levels (see Intel external design spec, table 48-29)
  - No hardware blink.

gpio: ich: Add output levels cache support

2014-03-19T08:58:23+00:00

This patch allows GPIO driver to cache GPIO_LVL output registers. The aim is to
support chipsets on which GPIO_LVL value can't be read for output pins.

Caching output levels implies the first output values reading as 0. The driver
so can't be aware of set values GPIOs by bootloader or BIOS.

gpio: ich: Add support for multiple register addresses

2014-03-19T08:58:22+00:00

This patch introduces regs and reglen pointers which allow a chipset to have
register addresses differing from ICH ones.

gpio: ich: Add blink capability option

gpio/pinctrl: make gpio_chip members typed boolean

2013-12-04T13:42:46+00:00

This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

gpio: use dev_get_platdata()

2013-08-16T13:24:35+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.
