mmc: mediatek: fix incorrect register setting of hs400_cmd_int_delay

2019-01-28T11:49:28Z

to set cmd internal delay, need set PAD_TUNE register but not PAD_CMD_TUNE register. Signed-off-by: Chaotian Jing Fixes: 1ede5cb88a29 ("mmc: mediatek: Use data tune for CMD line tune") Cc: stable@vger.kernel.org # v4.12+ Signed-off-by: Ulf Hansson

mmc: mediatek: Add MMC_CAP_SDIO_IRQ support

2018-12-19T09:16:15Z

This patch enables support SDIO IRQs. It enables MMC_CAP_SDIO_IRQ & MMC_CAP2_SDIO_IRQ_NOTHREAD and implement the ->ack_sdio_irq callback. Signed-off-by: Jjian Zhou Signed-off-by: Chaotian Jing Signed-off-by: Yong Mao Signed-off-by: Ulf Hansson

mmc: mediatek: drop too much code of tuning method

2018-10-15T13:00:29Z

the tuning code is becoming more and more bloated, let's make the set cmd/data delay to inline function to avoid too much redundant code. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: add MT8183 MMC driver support

2018-10-15T13:00:29Z

MT8183 puts the tune register at top layer, so need add new code to support it. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: tune CMD/DATA together

2018-10-15T13:00:29Z

for MSDC IP which supports both data tune and async fifo, it can tune cmd/data together. which can save the time and make the tune result of CMD more stable as data line are 4bit or 8bit. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: fix cannot receive new request when msdc_cmd_is_ready fail

2018-10-15T13:00:29Z

when msdc_cmd_is_ready return fail, the req_timeout work has not been inited and cancel_delayed_work() will return false, then, the request return directly and never call mmc_request_done(). so need call mod_delayed_work() before msdc_cmd_is_ready() Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: fill the actual clock for mmc debugfs

2018-10-15T13:00:29Z

as the mmc core layer has the mmc->actual_clock, so fill it and drop msdc_host->sclk. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: add bus_clk control

2018-10-08T10:53:24Z

when gate MSDC0_HCLK, access register will hang, even the MSDC driver will never accessing register after HCLK was gated, but for safety, need gate the bus_clk(which used to access register) too. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: add 64G DRAM DMA support

2018-05-02T13:08:51Z

MT2712 MSDC supports 64G DRAM DMA access, it needs update gpd/bd structure. Signed-off-by: Chaotian Jing Signed-off-by: Ulf Hansson

mmc: mediatek: use of_device_get_match_data()

2018-05-02T13:08:48Z

The usage of of_device_get_match_data() reduce the code size a bit. Also, the only way to call msdc_drv_probe() is to match an entry in msdc_of_ids[], so of_id cannot be NULL. Signed-off-by: Ryder Lee Signed-off-by: Ulf Hansson
