| | * mtd: pxa3xx_nand: enable multiple chip select supportLei Wen2011-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current pxa3xx_nand controller has two chip select which both be workable. This patch enable this feature. Update platform driver to support this feature. Another notice should be taken that: When you want to use this feature, you should not enable the keep configuration feature, for two chip select could be attached with different nand chip. The different page size and timing requirement make the keep configuration impossible. Signed-off-by: Lei Wen <leiwen@marvell.com>

| * | ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: pxa: fix gpio_to_chip() clash with gpiolib namespaceLinus Walleij2011-07-11
| | | | | | | | | | | | | The PXA platform code has a static inline helper called gpio_to_chip which clashes with the gpiolib namespace if we try to expose the function with the same name from gpiolib, and it's still confusing even if we don't do that.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

|/ | | | | | | | | | | | | | | | | | | | | | We now: * check for a v3 controller before setting 8-bit bus width * offer a callback for platform code to switch to 8-bit mode, which allows non-v3 controllers to support it * rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify that the board designers have indeed brought out all the pins for 8-bit to the slot. We were previously relying only on whether the *controller* supported 8-bit, which doesn't tell us anything about the pin configuration in the board design. This fixes the MMC card regression reported by Maxim Levitsky here: http://thread.gmane.org/gmane.linux.kernel.mmc/4336 by no longer assuming that 8-bit works by default.

| | | | | | | | | | | | | | | | | | Try to keep minimum ifdef in ssp.h.
