mmc: core: Add parameter use_blk_mq

2017-12-11T11:44:33+00:00

Until mmc has blk-mq support fully implemented and tested, add a parameter use_blk_mq, set to true if config option MMC_MQ_DEFAULT is selected, which it is by default. Signed-off-by: Adrian Hunter Acked-by: Linus Walleij Signed-off-by: Ulf Hansson Tested-by: Linus Walleij

mmc: core: Make mmc_pre_req() and mmc_post_req() available

2017-12-11T11:44:32+00:00

mmc: core: use usleep_range rather than HZ magic in mmc_delay()

2017-12-11T11:44:29+00:00

Documentation/timers/timers-howto.txt recommends to use usleep_range for delays 1-20ms. Let's adhere to it. No need for messing with HZ and still do busy looping these days. Signed-off-by: Wolfram Sang Signed-off-by: Ulf Hansson

mmc: core: Factor out mmc_host_set_uhs_voltage()

2017-10-30T10:45:57+00:00

Factor out mmc_host_set_uhs_voltage() so it can be reused. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson

mmc: core: Export a few functions needed for blkmq support

2017-10-30T10:45:56+00:00

The following functions are needed by the mmc block device driver, once it converts to blkmq, therefore let's export them. mmc_start_bkops() mmc_start_request() mmc_retune_hold_now() mmc_retune_release() Signed-off-by: Adrian Hunter Reviewed-by: Linus Walleij Signed-off-by: Ulf Hansson

mmc: core: Add support for handling CQE requests

Add core support for handling CQE requests, including starting, completing and recovering. Signed-off-by: Adrian Hunter Reviewed-by: Linus Walleij Signed-off-by: Ulf Hansson

mmc: core: Introduce host claiming by context

2017-10-30T10:45:49+00:00

Currently the host can be claimed by a task. Change this so that the host can be claimed by a context that may or may not be a task. This provides for the host to be claimed by a block driver queue to support blk-mq, while maintaining compatibility with the existing use of mmc_claim_host().
