| | | | | | | | | | | | | | | | | | | | | | | | | | | | The TMOUT register is set to 0xffffffff at probe time but isn't set after suspend/resume. Add an init of this value. No problems were observed without this (it will also be set in __dw_mci_start_request if there is data to send), but it makes the register dump before and after suspend cleaner.

| * mmc: dw_mmc: Honor requests to set the clock to 0Doug Anderson2013-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the dw_mmc driver would ignore any requests to disable the card's clock. This doesn't seem like a good thing in general, but had one extra bad side effect in the following situation: * mmc core would set clk to 400kHz at boot time while scanning * mmc core would set clk to 0 since no card, but it would be ignored. * suspend to ram and resume; clocks in the dw_mmc IP block are now 0 but dw_mmc thinks that they're 400kHz (it ignored the set to 0). * insert card * mmc core would set clk to 400kHz which would be considered a no-op. Note that if there is no card in the slot and we do a suspend/resume cycle, we _do_ still end up with differences in a dw_mmc register dump, but the differences are clock related and we've got the clock disabled both before and after, so this should be OK.

| * mmc: dw_mmc: don't queue up a card detect at slot startupDoug Anderson2013-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MMC subsystem handles looking for a card at probe time. Queuing up our own can race with the rest of the MMC subsystem and cause problems if we get unlucky with timing. Just remove driver own detection triggering. While progressing the request from 'mmc_rescan', if 'dw_mci_work_routine_card' routine is activated, it will cancel the current request. The problem case is that 'mmc_rescan' is prior to 'dw_mci_work_routine_card' from host own. Specifically, the following message shows the detection problem in driver's probing. It would get an err -123 (-ENOMEDIUM) during probe. [ 4.216595] dwmmc_exynos 12210000.dwmmc1: Using internal DMA controller.

Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences. Any errors are likely mine.

We restore the context in the .runtime_resume callback from the existing register caches to adapt to this situation. We also want to make sure the registers are in a known state while restoring context in the case when the power domain did not drop the power, since there are restrictions for the order of writing to these registers. To handle this, we clear the registers in the .runtime_suspend callback.

Writes to the MMCIPOWER register must be separated by three MCLK cycles. Previously no issues has been observered, but using higher ARM clock frequencies on STE- platforms has triggered this problem. The MMCICLOCK register is written to in .set_ios and for some data transmissions for SDIO. We do not need a delay at the data transmission path, because sending and receiving data will require more than three clock cycles. Then we use a simple logic to only delay in .set_ios and thus we don't affect throughput performance.

When returning from idle, entering .runtime_resume callback, the pins are restored to default state.

Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

| * mmc: omap_hsmmc: use the generic config for omap2plus devicesAmarinder Bindra2013-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP's hs_mmc driver is used for MMC controller operation on many omap2plus SoCs (OMAP2430, OMAP3, 4, 5 and AM335x). Considering that the device tree entries are already present for these, allow the driver to be built using the config ARCH_OMAP2PLUS rather than individually adding a config for each SoC to enable the support. Use COMPILE_TEST to enable the build for other platforms.

| * mmc: omap_hsmmc: clear status flags before starting a new commandFrancesco Lavra2013-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1f6b9fa40e76fffaaa0b3bd6a0bfdcf1cdc06efa consolidated writes to the STAT register in one location, moving them from omap_hsmmc_do_irq() to omap_hsmmc_irq(). This move has the unwanted side effect that the controller status flags are potentially cleared after a new command has been started as a consequence of reading the previous status flags. This means that if the new command changes the status flags before the IRQ routine returns, those flags may be cleared without handling the event which asserted them, and thus missing the event. Move the writing of the STAT register back in omap_hsmmc_do_irq(), before handling the status flags which generated the interrupt.
