mmc: use .multi_io_quirk on tmio_mmc

2014-09-09T12:15:07+00:00

Now, tmio_mmc can use .multi_io_quirk callback instead of MMC_CAP2_NO_MULTI_READ flags. let's use it. Signed-off-by: Kuninori Morimoto Acked-by: Lee Jones Signed-off-by: Ulf Hansson

mmc: tmio: add actual clock support as option

2014-09-09T11:59:16+00:00

Some controller is supporting actual clock on SD_CLK_CTRL :: DIV[7:0]. Renesas SH-Mobile SDHI doesn't support, but, Renesas R-Car SDHI supports it. This patch adds new TMIO_MMC_CLK_ACTUAL flag for it.

mmc: tmio: remove Renesas specific #ifdef

2014-09-09T11:59:15+00:00

mmc: tmio: add TMIO_MMC_SDIO_STATUS_QUIRK

2014-09-09T11:59:14+00:00

Renesas R-Car SDHI should set reserved bits on CTL_SDIO_STATUS register when writing.

mmc: tmio: control multiple block transfer mode

2014-09-09T11:59:14+00:00

Renesas SDHI has "Multiple Block Transfer Mode" settings on SD_CMD register which controls CMD12 automatically. This patch cares it, because CMD12 is not needed when CMD53 (= SD_IO_RW_EXTENDED) [Kuninori Morimoto: tidyuped for upstreaming enabled this flags for all SH-Mobile/R-Car] Tested-by: Nguyen Xuan Nui Tested-by: Hiep Cao Minh Signed-off-by: Shinobu Uehara Signed-off-by: Kuninori Morimoto Signed-off-by: Ulf Hansson

mmc: tmio: care about DMA tx/rx addr offset

2014-09-09T11:59:13+00:00

Basically, SD_BUF0 Tx/Rx addresses are same in normal TMIO controller, but, it is different on Renesas R-Car SDHI controller if it uses DMAC (Rx address needs to add 0x2000 to Tx address) This patch adds new .dma_rx_offset and cares it Tested-by: Nguyen Xuan Nui Tested-by: Hiep Cao Minh Acked-by: Laurent Pinchart Acked-by: Ben Dooks Signed-off-by: Kuninori Morimoto Signed-off-by: Ulf Hansson

mmc: tmio: add new TMIO_MMC_HAVE_HIGH_REG flags

2014-01-13T17:48:24+00:00

The accessibility checking method to the higher register was added by 69d1fe18e92afb (mmc: tmio: only access registers above 0xff, if available) But, it doesn't care 32bit register. It is impossible to calculate it from the resource size, since there is 16/32 bit register IP (e.g. VERSION is located on 0xe2 if 16bit register, but it is located on 0x1c4 if 32bit register). This patch adds new TMIO_MMC_HAVE_HIGH_REG flags, tmio_mmc driver has it, and sh_mobile_sdhi doesn't have it today. Signed-off-by: Kuninori Morimoto Signed-off-by: Chris Ball

mmc: tmio: bus_shift become tmio_mmc_data member

2014-01-13T17:48:23+00:00

.bus_shift is used to 16/32bit register access offset calculation on tmio driver. tmio_mmc_xxx is used from Toshiba/Renesas now, but this bus_shift value depends on HW IP. This patch moves .bus_shift to tmio_mmc_data member and sets it on each driver. Signed-off-by: Kuninori Morimoto Signed-off-by: Chris Ball

Revert "mmc: tmio-mmc: Remove .set_pwr() callback from platform data"
