ARM: 7588/1: amba: create a resource parent registrator

2012-12-03T11:15:35+00:00

This creates amba_apb_device_add_res() and
amba_ahb_device_add_res() respectively, to add devices with
another parent than iomem_resource. This is needed to specify
that a device is contained in a specific IO range.

Pull spi updates from Mark Brown:
 "No framework work here, only a bunch of driver updates of varying
  sizes:

   - Factoring out of the core hardware support from the MXS MMC driver
     by Marek Vasut to allow the hardware to also be used for SPI.
   - Lots of error handling cleanups from Guenter Roeck
   - Removal of the existing Tegra driver which is quite comprehensively
     broken as detailed in the changelog for the removal.
   - DT suppport for the PL022 and GPIO drivers.
   - pinctrl support for OMAP and PL022."

Pulling from Mark Brown as Grant Likely is still busy moving.

serial: pl011: delete reset callback

2012-09-10T23:33:02+00:00

Since commit 4fd0690bb0c3955983560bb2767ee82e2b197f9b
"serial: pl011: implement workaround for CTS clear event issue"
the PL011 UART is no longer at risk to hang up, so get rid
of the callback altogether.

spi/pl022: Add chip select handling via GPIO

2012-08-22T19:00:44+00:00

This patch adds the ability for the driver to control the chip select directly.
This enables independence from cs_control callbacks.  Configurable via
platform_data, to be extended as DT in the following patch.

Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-arm

2012-08-01T23:41:07+00:00

Pull ARM DMA engine updates from Russell King:
 "This looks scary at first glance, but what it is is:
   - a rework of the sa11x0 DMA engine driver merged during the previous
     cycle, to extract a common set of helper functions for DMA engine
     implementations.
   - conversion of amba-pl08x.c to use these helper functions.
   - addition of OMAP DMA engine driver (using these helper functions),
     and conversion of some of the OMAP DMA users to use DMA engine.

  Nothing in the helper functions is ARM specific, so I hope that other
  implementations can consolidate some of their code by making use of
  these helpers.

  This has been sitting in linux-next most of the merge cycle, and has
  been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
  and given it my best shot on my broken platforms which have the
  amba-pl08x controller.

  The last point is the addition to feature-removal-schedule.txt, which
  will have a merge conflict.  Between myself and TI, we're planning to
  remove the old TI DMA implementation next year."

Fix up trivial add/add conflicts in Documentation/feature-removal-schedule.txt
and drivers/dma/{Kconfig,Makefile}

Get rid of the unnecessary checks in dma_slave_config utilizing
the DMA direction.  This allows us to move the computation of
cctl to the prepare function.
