mmc: dw_mmc: Use active DDR mode flag

2014-12-12T19:09:01Z

The card_caps bit should denote the card capability to use DDR mode, but we need the flag indicating that the DDR mode is active. Signed-off-by: Andrew Gabbasov

mmc: Fix block length for DDR mode

2014-12-12T19:08:38Z

Block length for write and read commands is fixed to 512 bytes when the card is in Dual Data Rate mode. If block length read from CSD is different, make sure the driver will use correct length in all further calculations and settings. Signed-off-by: Andrew Gabbasov

mmc: Fix Dual Data Rate capability recognition

2014-12-12T19:08:21Z

Since the driver doesn't work in 1.2V or 1.8V signaling level modes, Dual Data Rate mode can be supported by the driver only if it is supported by the card in regular 3.3V mode. So, check for a particular single bit in card type field. Signed-off-by: Andrew Gabbasov

mmc: Fix handling of bus widths and DDR card capabilities

2014-12-12T19:08:06Z

If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask, it is never cleared, even if switching to DDR mode fails, and if the controller driver uses this flag to check the DDR mode, it can take incorrect actions. Also, DDR related checks in mmc_startup() incorrectly handle the case when the host controller does not support some bus widths (e.g. can't support 8 bits), since the host_caps is checked for DDR bit, but not bus width bits. This fix clearly separates using of card_caps bitmask, having there the flags for the capabilities, that the card can support, and actual operation mode, described outside of card_caps (i.e. bus_width and ddr_mode fields in mmc structure). Separate host controller drivers may need to be updated to use the actual flags. Respectively, the capabilities checks in mmc_startup are made more correct and clear. Also, some clean up is made with errors handling and code syntax layout. Signed-off-by: Andrew Gabbasov

mmc: exynos_dw-mmc: change debug message

MMC: fix user capacity for partitioned eMMC card

2014-12-12T18:28:04Z

if the card claims to be high capacity and the card is partitioned the capacity shall still be read from ext_csd SEC_COUNT even if the resulting capacity is smaller than 2 GiB Signed-off-by: Markus Niebel Acked-by: Jaehoon Chung

mmc: Cosmetic fix for nicer, aligned device list printout

2014-12-12T18:08:47Z

If print_mmc_devices() was called with a '\n' separator (as done for example by the "mmc list" command), it offset the 2-nd and all subsequent lines by one space. Fixing this. Signed-off-by: Lubomir Popov

omap_hsmmc: Board-specific TWL4030 MMC power initializations

2014-12-05T02:28:15Z

Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.
