After commit 26b88520 ("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 730c9b7e ("[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. Signed-off-by:

For several MoviNAND eMMC parts, there are known issues with secure erase and secure trim. For these specific MoviNAND devices, we skip these operations. Specifically, there is a bug in the eMMC firmware that causes unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE enabled.

The documentation for the dw_mmc part says that the low power mode should normally only be set for MMC and SD memory and should be turned off for SDIO cards that need interrupts detected. The best place I could find to do this is when the SDIO interrupt was first enabled. I rely on the fact that dw_mci_setup_bus() will be called when it's time to reenable. Signed-off-by:

Data transfer will be continued until all the bytes are transmitted, even if data crc error occurs during a multiple-block data transfer. This means RXDR/TXDR interrupts will occurs until data transfer is terminated. Early setting of host->sg to NULL prevents going into xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts occurs. And checking error interrupt status in the xxx_data_pio functions is no need because dw_mci_interrupt does do the same. This patch also removes it. Signed-off-by:

Datasheet of SYNOPSYS mentions that DTO(Data Transfer Over) interrupt will be raised even if some error interrupts, however it is actually found that DTO does not occur. SYNOPSYS has confirmed this issue. Current implementation defers the call of tasklet_schedule until DTO when the error interrupts is happened. This patch fixes error handling. Signed-off-by:

RINTSTS status includes masked interrupts as well as unmasked. data_status and cmd_status are set by value of RINTSTS in interrupt handler and tasklet finally uses it to decide whether error is happened or not. In addition, MINTSTS status is used for setting data_status in PIO. Masked error interrupt will not be handled and that status can be considered non-error case. Signed-off-by:

Even if the datasheet says that the not busy flag has to be used only for write operations, it's false except for version lesser than v2xx. Not waiting on the not busy flag for read operations can cause the controller to hang-up during the initialization of some SD cards with DMA after the first CMD6 -- the next command is sent too early.

Since commit 30832ab5 ("mmc: sdhci: Always pass clock request value zero to set_clock host op") was merged, esdhc_set_clock starts hitting "if (clock == 0)" where ESDHC_SYSTEM_CONTROL has been operated. This causes SDHCI card-detection function being broken. Fix the regression by moving "if (clock == 0)" above ESDHC_SYSTEM_CONTROL operation. Signed-off-by:

Pull OLPC platform updates from Andres Salomon: "These move the OLPC Embedded Controller driver out of arch/x86/platform and into drivers/platform/olpc. OLPC machines are now ARM-based (which means lots of x86 and ARM changes), but are typically pretty self-contained.. so it makes more sense to go through a separate OLPC tree after getting the appropriate review/ACKs." * 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc: x86: OLPC: move s/r-related EC cmds to EC driver Platform: OLPC: move global variables into priv struct Platform: OLPC: move debugfs support from x86 EC driver x86: OLPC: switch over to using new EC driver on x86 Platform: OLPC: add a suspended flag to the EC driver Platform: OLPC: turn EC driver into a platform_driver Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it drivers: OLPC: update various drivers to include olpc-ec.h Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

Pull arm-soc cpuidle enablement for OMAP from Olof Johansson: "Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but didn't go in because the pull request ended up rejected. So it just got merged, and we got this staged branch that enables the coupled cpuidle code on OMAP. With a stable git workflow from the other maintainer we could have staged this earlier, but that wasn't the case so we have had to merge it late. The alternative is to hold it off until 3.7 but given that the code is well-isolated to OMAP and they are eager to see it go in, I didn't push back hard in that direction." * tag 'pm2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: CPUidle: Open broadcast clock-event device.
