gpio/sodaville: Convert sodaville driver to new irqdomain API

2012-04-10T20:20:55+00:00

The irqdomain api changed significantly in v3.4 which caused a build
failure for this driver.

Pull GPIO changes for v3.4 from Grant Likely:
 "Primarily gpio device driver changes with some minor side effects
  under arch/arm and arch/x86.  Also includes a few core changes such as
  explicitly supporting (electrical) open source and open drain outputs
  and some help for parsing gpio devicetree properties."

Fix up context conflict due to Laxman Dewangan adding sleep control for
the tps65910 driver separately for gpio's and regulators.

gpio/sodaville: Mark broken due to core irqdomain migration

2012-03-23T08:56:10+00:00

The sodaville driver doesn't build anymore due to the transition to
common irq_domain in the core code.  It needs to be reworked, but
the rework isn't trivial.  Since this is a new driver anyway for
v3.4, mark it as broken now and a fixup patch can re-enable it when
the rework change has been tested.

gpio: Move GE GPIO driver to reside within GPIO subsystem

2012-03-16T16:08:08+00:00

The GE GPIO driver provides basic support (set direction, read/write state)
for the GPIO provided on some GE single board computers. This patch moves
the driver from the 86xx specific platform directrory to the GPIO subsystem
so that it can be used on non-86xx boards.

gpio: Add a driver for Sodaville GPIO controller

2012-02-03T23:13:25+00:00

Sodaville has GPIO controller behind the PCI bus. To my suprissed it is
not the same as on PXA.

The interrupt & gpio chip can be referenced from the device tree like
from any other driver. Unfortunately the driver which uses the gpio
interrupt has to use irq_of_parse_and_map() instead of
platform_get_irq(). The problem is that the platform device (which is
created from the device tree) is most likely created before the
interrupt chip is registered and therefore irq_of_parse_and_map() fails.

In theory the driver works as module. In reality most of the irq
functions are not exported to modules and it is possible that _this_
module is unloaded while the provided irqs are still in use.

ARM/mx35/3ds: gpio: add mc9s08dz60 gpio function

2012-01-30T14:49:08+00:00

we only use the gpio function of mc9s08dz60 mcu chip, so just
add the gpio driver, as this mcu will never be used in other board.

gpio/it8761e: Restrict it8761e gpio driver to x86.

2012-01-18T00:43:09+00:00

This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM.  It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.
