mmc: dw_mmc: Slot quirk "disable-wp" is deprecated.

2014-08-11T09:42:39Z

Slot quirks "disable-wp" is deprecated. Instead, use the host quirk "disable-wp". (Because the slot-node is removed in dt-file.) Signed-off-by: Jaehoon Chung Tested-by: Sachin Kamat Acked-by: Seungwon Jeon Reviewed-by: Doug Anderson Tested-by: Doug Anderson Signed-off-by: Ulf Hansson

mmc: dw_mmc: remove unused member variable.

2014-05-12T22:04:33Z

Since using the device-tree, didn't use the callback pointer. So removed the unused callback pointer. When the set_power callback is used, it should be added in future. Signed-off-by: Jaehoon Chung Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: dw_mmc: guarantee stop-abort cmd in data errors

2013-09-26T01:35:40Z

In error cases, DTO interrupt may or may not be generated depending on remained data. Stop/Abort command ensures DTO generation for that situation. Currently if 'stop' field of data is empty, there is no stop/abort command. So, it could hang waiting DTO. This change reinforces these cases.

mmc: dw_mmc: control card read threshold

2013-09-26T01:34:39Z

Card Read Threshold should be ensured that the card clock does not stop in the middle of a block of data being transferred from the card to the Host. Specially, clock stop is allowed in fast transfer such as HS200 or SDR104 mode. And so, it should be enabled. Signed-off-by: Seungwon Jeon Tested-by: Alim Akhtar Signed-off-by: Chris Ball

mmc: dw_mmc: adjust the fifoth with block size

2013-09-26T01:34:18Z

This change helps to choose msize, rx_watermark and tx_watermark depending on block size for IDMAC mode. For SDIO block size can be variable, so if these values are set incorrectly, card clock may stop. Signed-off-by: Seungwon Jeon Tested-by: Alim Akhtar Signed-off-by: Chris Ball

mmc: dw_mmc: Remove DW_MCI_QUIRK_NO_WRITE_PROTECT

2013-02-24T19:36:55Z

The original quirk was added in the change 'mmc: dw_mmc: add quirk to indicate missing write protect line'. The original quirk was added at a controller level even though each slot has its own write protect (so the quirk should be at the slot level). A recent change (mmc: dw_mmc: Add "disable-wp" device tree property) added a slot-level quirk and support for the quirk directly to dw_mmc.

mmc: dw_mmc: Add "disable-wp" device tree property

2013-02-24T19:36:52Z

The "disable-wp" property is used to specify that a given SD card slot doesn't have a concept of write protect. This eliminates the need for special case code for SD slots that should never be write protected (like a micro SD slot or a dev board). The dw_mmc driver is special in needing to specify "disable-wp" because the lack of a "wp-gpios" property means to use the special purpose write protect line. On some other mmc devices the lack of "wp-gpios" means that write protect should be disabled.

mmc: dw_mmc: Add sdio power bindings

Add dt-based retrieval of host sdio pm capabilities. Based on the dt based discovery do a bus init in the resume function. Signed-off-by: Olof Johansson Signed-off-by: Abhilash Kesavan Signed-off-by: Chris Ball

mmc: Standardise capability type

There are discrepancies with regards to how MMC capabilities are carried throughout the subsystem. Let's standardise them to eliminate any confusion. Signed-off-by: Lee Jones Signed-off-by: Chris Ball

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
