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.

2012-01-11UBI: fix debugging messagesArtem Bityutskiy
Patch ab50ff684707031ed4bad2fdd313208ae392e5bb broke UBI debugging messages: before that commit when UBI debugging was enabled, users saw few useful debugging messages after attaching an MTD device. However, that patch turned 'dbg_msg()' into 'pr_debug()', so to enable the debugging messages users have to enable them first via /sys/kernel/debug/dynamic_debug/control, which is very impractical. This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just as it was before the breakage.

2012-01-11block: Introduce blk_set_stacking_limits functionMartin K. Petersen
Stacking driver queue limits are typically bounded exclusively by the capabilities of the low level devices, not by the stacking driver itself. This patch introduces blk_set_stacking_limits() which has more liberal metrics than the default queue limits function. This allows us to inherit topology parameters from bottom devices without manually tweaking the default limits in each driver prior to calling the stacking function. Since there is now a clear distinction between stacking and low-level devices, blk_set_default_limits() has been modified to carry the more conservative values that we used to manually set in blk_queue_make_request().

2012-01-11mb86a20s: Add a few more register settings at the init seqMauro Carvalho Chehab
Some time ago, Manoel sent us a patch adding more stuff to the init sequence. However, his patch were also doing non-related stuff, by changing the init logic without any good reason. So, it was asked for him to submit a patch with just the data that has changed, in order to allow us to better analyze it. As he didn't what it was requested, I finally found some time to dig into his init sequence and add it here. Basically, new stuff is added there. There are a few changes: 1) The removal of the extra (duplicated) logic that puts the chip into the serial mode; 2) Some Viterbi VBER measurement init data was changed from 0x00 to 0xff for layer A, to match what was done for layers B and C. None of those caused any regressions and both make sense on my eyes. The other parameters additions actually increased the tuning quality for some channels. Yet, some channels that were previously discovered with scan disappered, while others appeared instead. This were tested in Brasilia, with an external antena. At the overall, it is now a little better. So, better to add these, and then try to figure out a configuration that would get even better scanning results.
