mmc: mediatek: add latch-ck support

2017-11-02T14:20:26+00:00

some platform(eg.mt2701) does not support "stop clk fix", in this case, need set correct latch-ck to avoid crc error caused by stop clock block-internally. Signed-off-by: Chaotian Jing Tested-by: Sean Wang Signed-off-by: Ulf Hansson

mmc: mediatek: add support of source_cg clock

2017-11-02T14:20:25+00:00

source clock need an independent cg to control, when doing clk mode switch, need gate source clock to avoid hw issue(multi-bit sync hw hang) Signed-off-by: Chaotian Jing Tested-by: Sean Wang Signed-off-by: Ulf Hansson

mmc: mediatek: add stop_clk fix and enhance_rx support

2017-11-02T14:20:25+00:00

mt2712 supports stop_clk fix and enhance_rx, which can improve host stability. Signed-off-by: Chaotian Jing Tested-by: Sean Wang Signed-off-by: Ulf Hansson

mmc: mediatek: add busy_check support

mmc: mediatek: make hs400_tune_response only for mt8173

2017-11-02T14:20:23+00:00

the origin design of hs400_tune_response is for mt8173 because of mt8173 has a special design. for doing that, we add a new member "compatible", by now it's only for mt8173. Signed-off-by: Chaotian Jing Tested-by: Sean Wang Signed-off-by: Ulf Hansson

mmc: mediatek: add support of mt2701/mt2712

2017-10-30T11:02:44+00:00

mt2701/mt2712 has 12bit clock div, which is not compatible with mt8135/mt8173. and, some additional features will be added in mt2701/mt2712, so that need distinguish it by comatibale name. Signed-off-by: Chaotian Jing Tested-by: Sean Wang Signed-off-by: Ulf Hansson
