gpio: fix spurious printk when freeing a gpio

2010-07-27T21:32:07+00:00

When freeing a gpio that has not been exported, gpio_unexport() prints a
debug message when it should just fall through silently.

Example spurious message:

	gpio_unexport: gpio0 status -22

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.

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.
