2011-08-12ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King
Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

2011-06-21net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-14plat-nomadik: implement safe switch sequence for Alt-CRabin Vincent
Setting pinmux alternative C for a GPIO pin is actually not so easy since it ivolves setting value "1" in two registers, and since the combined result will take effect for intermediate values (01 or 10) this will cause glitches while you wrote one register but have not yet written the other. This patch implements a series of kludges including an optional machine-specific callback to avoid glitches when changing pin mux mode to alternative C.

2011-01-04dmaengine: dma40: Add support to split up large elementsPer Forlin
The maximum transfer size of the stedma40 is (64k-1) x data-width. If the transfer size of one element exceeds this limit the job is split up and sent as linked transfer. Signed-off-by: Per Forlin <per.forlin@linaro.org> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-12-08nomadik-gpio: allow sleep mode dir/pull to differ from normal modeRabin Vincent
In the nomadik GPIO pin configuration, allow the sleep mode direction and pull configurations to differ from the ones for the normal state. PIN_SLPM_PULL_*, PIN_SLPM_INPUT, PIN_SLPM_OUTPUT* macros are provided for this. Since the hardware does not allow seperate configurations for sleep mode and normal mode, this is implemented by having software remux the configurations as necessary.
