mmc: omap: Fix I2C dependency and make driver usable with device tree Some features can be configured by the companion I2C chips, which may not be available at the probe time. Fix the issue by returning -EPROBE_DEFER when the MMC controller slots are not configured. While at it, let's also add minimal device tree support so omap24xx platforms can use this driver without legacy mode since we claim to support device tree for mach-omap2 based systems. Although adding the minimal device tree support is not strictly a fix, it does remove one of the last blockers for dropping a bunch of legacy platform data for mach-omap2.

mmc: omap: fix broken PIO mode After commit 26b88520b80695a6fa5fd95b5d97c03f4daf87e0 ("mmc: omap_hsmmc: remove private DMA API implementation"), the Nokia N800 here stopped booting: [ 2.086181] Waiting for root device /dev/mmcblk0p1... [ 2.324066] Unhandled fault: imprecise external abort (0x406) at 0x00000000 [ 2.331451] Internal error: : 406 [#1] ARM [ 2.335784] Modules linked in: [ 2.339050] CPU: 0 Not tainted (3.6.0-rc3 #60) [ 2.344146] PC is at default_idle+0x28/0x30 [ 2.348602] LR is at trace_hardirqs_on_caller+0x15c/0x1b0 ... This turned out to be due to memory corruption caused by long-broken PIO code in drivers/mmc/host/omap.c. (Previously, this driver had been using DMA; but the above commit caused the MMC driver to fall back to PIO mode with an unmodified Kconfig.) The PIO code, added with the rest of the driver in commit 730c9b7e6630f786fcec026fb11d2e6f2c90fdcb ("[MMC] Add OMAP MMC host driver"), confused bytes with 16-bit words. This bug caused memory located after the PIO transfer buffer to be corrupted with transfers larger than 32 bytes. The driver also did not increment the buffer pointer after the transfer occurred. This bug resulted in data corruption during any transfer larger than 64 bytes.

mmc: omap: Fix broken reg_shift initialization Commit fa550189 (mmc: core: Prevent eMMC VCC supply to be cut from late init) slightly affected timings for how things are done for the omap MMC driver causing the MMC cards not getting detected any longer. Turns out this was caused by buggy reg_shift initialization in the omap MMC driver that was happening after mmc_add_host() was being called.

omap: remove BUG_ON for disabled interrupts Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

mmc/omap: make mmci-omap using platform_driver_probe A pointer to mmc_omap_probe which lives in .init.text is passed to the core via platform_driver_register and so the kernel might oops if probe is called after the init code is discarded. As requested by David Brownell platform_driver_probe is used instead of moving the probe function to .devinit.text. This saves some memory, but might have the downside that a device being registered after the call to mmc_omap_init but before the init sections are discarded will not be bound anymore to the driver.

mmc: remove multiwrite capability Relax requirements on host controllers and only require that they do not report a transfer count than is larger than the actual one (i.e. a lower value is okay). This is how many other parts of the kernel behaves so upper layers should already be prepared to handle that scenario. This gives us a performance boost on MMC cards.

mmc: Fix omap compile by replacing dev_name with dma_dev_name This patch fixes error: drivers/mmc/host/omap.c: In function 'mmc_omap_get_dma_channel': drivers/mmc/host/omap.c:1038: error: called object 'dev_name' is not a function Commit 06916639e2fed9ee475efef2747a1b7429f8fe76 adds a function called dev_name. This will cause a name conflict as dev_dbg calls dev_name(((host->mmc)->parent)). This same issue should not affect other drivers as they don't seem to use dev_name with dev_dbg.

MMC: OMAP: Do not busy wait for end of command for ever The limit was a fixed 100k limit in the busy loop, which is not accurate. It would better to have time limit for the worst case which occurs when sending 80 cycles at 400 kHz and takes about 200 microseconds, so limit the max time spend in the busy loop for some 250 microseconds.
