mmc: dw_mmc: constify dw_mci_idmac_ops in exynos back-end

2012-11-07T20:02:55Z

The of_device_id match data is now marked as const and must not be modified. This changes the dw_mmc to mark all pointers passing the dw_mci_drv_data or dw_mci_dma_ops structures as const, and also marks the static definitions as const. drivers/mmc/host/dw_mmc-exynos.c: In function 'dw_mci_exynos_probe': drivers/mmc/host/dw_mmc-exynos.c:234:11: warning: assignment discards 'const' qualifier from pointer target type [enabled by default] Signed-off-by: Arnd Bergmann Cc: Thomas Abraham Cc: Will Newton Signed-off-by: Chris Ball

mmc: sdhci-of-esdhc: disable CMD23 for some Freescale SoCs

2012-11-07T19:55:29Z

CMD23 causes lots of errors in kernel on some freescale SoCs (P1020, P1021, P1022, P1024, P1025 and P4080) when MMC card used, which is because these controllers does not support CMD23, even on the SoCs which declares CMD23 is supported. Therefore, we'll not use CMD23. Signed-off-by: Jerry Huang Signed-off-by: Shaohui Xie Acked-by: Anton Vorontsov Signed-off-by: Chris Ball

mmc: dw_mmc: convert the variable type of irq

2012-11-07T19:50:16Z

Even though platform_get_irq returns error, 'host->irq' always has an unsigned value. Less-than-zero comparison of an unsigned value is never true. Type of 'unsigned int' will be changed for 'int'. Signed-off-by: Seungwon Jeon Acked-by: Will Newton Signed-off-by: Chris Ball

UAPI: Remove empty non-UAPI Kbuild files

2012-10-17T11:31:15Z

Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells

mmc: core: Fixup broken suspend and eMMC4.5 power off notify

2012-10-07T21:41:45Z

This patch fixes up the broken suspend sequence for eMMC with sleep support. Additionally it reworks the eMMC4.5 Power Off Notification feature so it fits together with the existing sleep feature. The CMD0 based re-initialization of the eMMC at resume is re-introduced to maintain compatiblity for devices using sleep. A host shall use MMC_CAP2_POWEROFF_NOTIFY to enable the Power Off Notification feature. We might be able to remove this cap later on, if we think that Power Off Notification always is preferred over sleep, even if the host is not able to cut the eMMC VCCQ power.

mmc: dw_mmc: add support for exynos specific implementation of dw-mshc

2012-10-03T14:05:20Z

Samsung Exynos SoC's extend the dw-mshc controller for additional clock and bus control. Add support for these extensions and include provide device tree based discovery suppory as well. Signed-off-by: Thomas Abraham Acked-by: Will Newton Signed-off-by: Chris Ball

mmc: dw_mmc: add support for implementation specific callbacks

2012-10-03T14:05:19Z

The core dw-mshc controller driver can let platform specific implementations of the dw-mshc controller to control the hardware as required by such implementations. This is acheived by invoking implementation specific (optional) callbacks. Define the list of callbacks supported the add invocation points for the same.

mmc: dw_mmc: add quirk to indicate missing write protect line

2012-10-03T14:05:16Z

If the write protect pad of the controller is not connected to the write protect pin of the slot, the driver should be notified of this condition so that incorrect check for write protection by reading the WRTORT register can avoided. The get_ro platform callback can be used for in such cases, but with device tree support enabled, such platform callbacks cannot be supported. Add a new quirk for notifying the driver about the missing write protect line so the driver can assume that the card write protection is disabled.
