2014-01-10esdhc: Workaround for eSDHC clock glitch issueHaijun Zhang
A-003980: SDHC: Glitch is generated on the card clock with software reset or clock divider change Description: A glitch may occur on the SDHC card clock when the software sets the RSTA bit (software reset) in the system control register. It can also be generated by setting the clock divider value. The glitch produced can cause the external card to switch to an unknown state. The occurrence is not deterministic. Workaround: A simple workaround is to disable the SD card clock before the software reset, and enable it when the module resumes normal operation. The Host and the SD card are in a master-slave relationship. The Host provides clock and control transfer across the interface. Therefore, any existing operation is discarded when the Host controller is reset. The recommended flow is as follows: 1. Software disable bit[3], SDCLKEN, of the System Control Register 2. Trigger software reset and/or set clock divider 3. Check bit[3], SDSTB, of the Present State Register for stable clock 4. Enable bit[3], SDCLKEN, of the System Control Register Using the above method, the eSDHC cannot send command or transfer data when there is a glitch in the clock line, and the glitch does not cause any issue.

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.

2013-11-14ACPI / driver core: Store an ACPI device pointer in struct acpi_dev_nodeRafael J. Wysocki
Modify struct acpi_dev_node to contain a pointer to struct acpi_device associated with the given device object (that is, its ACPI companion device) instead of an ACPI handle corresponding to it. Introduce two new macros for manipulating that pointer in a CONFIG_ACPI-safe way, ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the ACPI_HANDLE() macro to take the above changes into account. Drop the ACPI_HANDLE_SET() macro entirely and rework its users to use ACPI_COMPANION_SET() instead. For some of them who used to pass the result of acpi_get_child() directly to ACPI_HANDLE_SET() introduce a helper routine acpi_preset_companion() doing an equivalent thing. The main motivation for doing this is that there are things represented by struct acpi_device objects that don't have valid ACPI handles (so called fixed ACPI hardware features, such as power and sleep buttons) and we would like to create platform device objects for them and "glue" them to their ACPI companions in the usual way (which currently is impossible due to the lack of valid ACPI handles). However, there are more reasons why it may be useful. First, struct acpi_device pointers allow of much better type checking than void pointers which are ACPI handles, so it should be more difficult to write buggy code using modified struct acpi_dev_node and the new macros. Second, the change should help to reduce (over time) the number of places in which the result of ACPI_HANDLE() is passed to acpi_bus_get_device() in order to obtain a pointer to the struct acpi_device associated with the given "physical" device, because now that pointer is returned by ACPI_COMPANION() directly. Finally, the change should make it easier to write generic code that will build both for CONFIG_ACPI set and unset without adding explicit compiler directives to it. Signed-off-by: Rafael J.

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.

Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. 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() ...

DMA bounce limit is the maximum direct DMA'able memory beyond which bounce buffers has to be used to perform dma operations. MMC queue layr relies on dma_mask but its calculation is based on max_*pfn which don't have uniform meaning across architectures. So make use of dma_max_pfn() which is expected to return the DMAable maximum pfn value across architectures.

2013-10-31mmc: core: Add MMC_CAP_RUNTIME_RESUME to resume at runtime_resumeUlf Hansson
In some environments it is to prefer to postpone the resume of the card device until runtime_resume is being carried out, since it will mean a signficant decrease of the total system resume time. The reason of the decreased resume time is simply because of the actual re-initalization of the card, which typically takes hundreds of milliseconds, is performed outside the resume sequence and wont thus affect it. For removable card, the detect work tries to re-detect the card to make sure it is still present, as a part of that sequence the card will also be runtime_resumed and thus also fully resumed. For a non-removable card, typically a mmc blk request will trigger a runtime_resume and thus fully resume the card. This also means the first request will likely suffer from an inital latency since the re-initialization of the card needs to be performed.

2013-10-31mmc: core: Improve runtime PM support during suspend/resume for sd/mmcUlf Hansson
The card device is considered as in-active after it has been suspended. To prevent any further runtime PM requests in suspend state, we then disable runtime PM. After the card device has been resumed, we shall consider it as active, like we also do after a probe sequence. When resumed, we can safely enable runtime PM again. This will make sure the PM core can request the card device to go to in-active state after a resume has been completed. Previously we had to wait for new pm_runtime_get->pm_runtime_put cycle to be executed. Additionally, once a resume has been carried out, update the last busy mark. At the moment this will have no effect but if the PM core will respect autosuspend enabled devices, when it directly triggers a runtime_suspend from a runtime_idle, it will mean the card device will be scheduled for a delayed runtime_suspend instead of done immediately.

2013-10-31mmc: core: Remove redundant mmc_power_up|off at runtime callbacksUlf Hansson
Commit "mmc: core: Push common suspend|resume code into each bus_ops" moved the responsibility for doing mmc_power_up|off into each suspend/resume bus_ops. When using MMC_CAP_AGGRESSIVE_PM, through the runtime callbacks, calls to mmc_power_up|off became redundant. When removing them, we are also able to remove the calls to mmc_claim|release_host, thus simplifing code a bit more.

2013-10-31mmc: Don't force card to active state when entering suspend/shutdownUlf Hansson
By adding a card state that records if it is suspended or resumed, we can accept asyncronus suspend/resume requests for the mmc and sd bus_ops. MMC_CAP_AGGRESSIVE_PM, will at request inactivity through the runtime bus_ops callbacks, execute a suspend of the the card. In the state were this has been done, we can receive a suspend request for the mmc bus, which for sd and mmc forced the card to active state by a pm_runtime_get_sync. In other words, the card was resumed and then immediately suspended again, completely unnecessary. Since the suspend/resume bus_ops callbacks for sd and mmc are now capable of handling asynchronous requests, we no longer need to force the card to active state before executing suspend. Evidently preventing the above sequence for MMC_CAP_AGGRESSIVE_PM. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>
