2012-01-11mmc: core: Fix voltage select in DDR modeGirish K S
This patch fixes the wrong comparison before setting the interface voltage in DDR mode. The assignment to the variable ddr before comaprison is either ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison is done with the extended csd value if ddr == EXT_CSD_CARD_TYPE_DDR_1_2V.

This patch adds support for sdio UHS cards per the version 3.0 spec. UHS mode is only enabled for version 3.0 cards when both the host and the controller support UHS modes. 1.8v signaling support is removed if both the card and the host do not support UHS. This is done to maintain compatibility and some system/card combinations break when 1.8v signaling is enabled when the host does not support UHS.

2012-01-11mmc: core: Use delayed work in clock gating frameworkSujit Reddy Thumma
Current clock gating framework disables the MCI clock as soon as the request is completed and enables it when a request arrives. This aggressive clock gating framework, when enabled, cause following issues: When there are back-to-back requests from the Queue layer, we unnecessarily end up disabling and enabling the clocks between these requests since 8MCLK clock cycles is a very short duration compared to the time delay between back to back requests reaching the MMC layer. This overhead can effect the overall performance depending on how long the clock enable and disable calls take which is platform dependent. For example on some platforms we can have clock control not on the local processor, but on a different subsystem and the time taken to perform the clock enable/disable can add significant overhead. Also if the host controller driver decides to disable the host clock too when mmc_set_ios function is called with ios.clock=0, it adds additional delay and it is highly possible that the next request had already arrived and unnecessarily blocked in enabling the clocks. This is seen frequently when the processor is executing at high speeds and in multi-core platforms thus reduces the overall throughput compared to if clock gating is disabled. Fix this by delaying turning off the clocks by posting request on delayed workqueue. Also cancel the unscheduled pending work, if any, when there is access to card. sysfs entry is provided to tune the delay as needed, default value set to 200ms.

2012-01-11mmc: debugfs: expose the SDCLK frq in sys iosGiuseppe CAVALLARO
This patch is to expose the actual SDCLK frequency in /sys/kernel/debug/mmcX/ios entry. For example, if the max clk for a normal speed card is 20MHz this is reported in /sys/kernel/debug/mmcX/ios. Unfortunately the actual SDCLK frequency (i.e. Baseclock / divisor) is not reported at all: for example, in that case, on Arasan HC, it should be 48/4=12 (MHz).

2012-01-11mmc: sdio: Fix to support any block size optimallyStefan Nilsson XK
This patch allows any block size to be set on the SDIO link, and still have an arbitrary sized packet (adjusted in size by using sdio_align_size) transferred in an optimal way (preferably one transfer). Previously if the block size was larger than the default of 512 bytes and the transfer size was exactly one block size (possibly thanks to using sdio_align_size to get an optimal transfer size), it was sent as a number of byte transfers instead of one block transfer. Also if the number of blocks was (max_blocks * N) + 1, the tranfer would be conducted with a number of blocks and finished off with a number of byte transfers. When doing this change it was also possible to break out the quirk for broken byte mode in a much cleaner way, and collect the logic of when to do byte or block transfer in one function instead of two.

2012-01-06Merge branch 'driver-core-next' into Linux 3.2Greg Kroah-Hartman
This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file, and it fixes the build error in the arch/x86/kernel/microcode_core.c file, that the merge did not catch. The microcode_core.c patch was provided by Stephen Rothwell <sfr@canb.auug.org.au> who was invaluable in the merge issues involved with the large sysdev removal process in the driver-core tree.
