linux.git/drivers/gpio, branch v2.6.35-rc4

drivers/gpio is platform-neutral

2010-06-29T22:29:32+00:00

Update Kconfig and Makefile in drivers/gpio to discourage inappropriate
addition of platform-specific code.

gpio: Fix inverted rdc321x gpio data out registers

2010-05-27T23:37:59+00:00

rdc_gpio_set_value_impl has the gpio data registers 1 and 2 inverted, fix this.

mfd: Change rdc321x resources flags to IORESOURCE_IO

2010-05-27T23:37:52+00:00

The rdc321x southbridge PCI device has no MEM PCI resources that we could
pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the
mem_base argument that we set to NULL. Changing the resources passed to
our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use
those resources as offsets to the PCI configuration space base address of
the southbridge device this is also more adequate.

gpio: rdc321x needs to select MFD_CORE

2010-05-27T23:37:48+00:00

Fix rdc321x-southbridge build:  GPIO_RDC321X needs to select
MFD_CORE so that the core is built at the same (or higher)
tristate level.

rdc321x-southbridge.c:(.devinit.text+0x6103): undefined reference to `mfd_add_devices'
rdc321x-southbridge.c:(.devexit.text+0xe5f): undefined reference to `mfd_remove_devices'

gpio: Update gfp/slab.h includes for rdc321x

2010-05-27T23:37:36+00:00

Implicit slab.h inclusion via percpu.h is about to go away.  Make sure
gfp.h or slab.h is included as necessary.

gpio: Add support for Janz VMOD-TTL Digital IO module

2010-05-27T23:37:33+00:00

The Janz VMOD-TTL is a MODULbus daughterboard which fits onto any MODULbus
carrier board. It essentially consists of some various logic and a Zilog
Z8536 CIO Counter/Timer and Parallel IO Unit.

The board must be physically configured with jumpers to enable a user to
drive output signals. I am only interested in outputs, so I have made this
driver as simple as possible. It only supports a very minimal subset of the
features provided by the Z8536 chip.

gpio: add Penwell gpio support

2010-05-27T16:12:42+00:00

Intel Penwell chip has two 96 pins GPIO blocks, which are very similiar as
Intel Langwell chip GPIO block, except for pin number difference. This
patch expends the original Langwell GPIO driver to support Penwell's.
