mmc: sdhci-pci: Fix default d3_retune for Intel host controllers

2017-10-27T08:39:12Z

commit eb701ce16a45ed9880897c48f05ee608d77c72e3 upstream. The default for d3_retune is true, but that was not being set in all cases, which results in eMMC errors because re-tuning has not been done. Fix by initializing d3_retune to true.

mmc: core: add driver strength selection when selecting hs400es

2017-10-12T09:56:19Z

commit fb458864d9a78cc433fec7979acbe4078c82d7a8 upstream. The driver strength selection is missed and required when selecting hs400es. So, It is added here.

mmc: sdhci-pci: Fix voltage switch for some Intel host controllers

2017-10-05T07:47:32Z

commit 6ae033689d7b1a419def78e8e990b0eab8bb6419 upstream. Some Intel host controllers (e.g. CNP) use an ACPI device-specific method to ensure correct voltage switching. Fix voltage switch for those, by adding a call to the DSM. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson Signed-off-by: Greg Kroah-Hartman

commit 01f5bbd17a8066b58dba9b5049fad504bce67322 upstream. mmc_init_request() depends on card->bouncesz so it must be calculated before blk_init_allocated_queue() starts allocating requests.

mmc: sdhci-xenon: add set_power callback

2017-08-30T12:11:47Z

Xenon sdh controller requests proper SD bus voltage select bits programmed even with vmmc power supply. Any reserved value(100b-000b) programmed in this field will lead to controller ignore SD bus power bit and keep its value at zero. Add set_power callback to handle this.

Commit 2a842acab109 ("block: introduce new block status code type") changed the error type but not in patches merged through the mmc tree, like commit 0493f6fe5bde ("mmc: block: Move boot partition locking into a driver op").

mmc: block: prevent propagating R1_OUT_OF_RANGE for open-ending mode

2017-08-21T11:32:31Z

We to some extent should tolerate R1_OUT_OF_RANGE for open-ending mode as it is expected behaviour and most of the backup partition tables should be located near some of the last blocks which will always make open-ending read exceed the capacity of cards.

mmc: host: omap_hsmmc: Add CMD23 capability to omap_hsmmc driver

2017-08-08T08:11:07Z

omap_hsmmc driver always relied on CMD12 to stop transmission. However if CMD12 is not issued at the correct timing, the card will indicate a out of range error. With certain cards in some of the DRA7 based boards, -EIO error is observed. By Adding CMD23 capability, the MMC core will send MMC_SET_BLOCK_COUNT command before MMC_READ_MULTIPLE_BLOCK/MMC_WRITE_MULTIPLE_BLOCK commands. commit a04e6bae9e6f12 ("mmc: core: check also R1 response for stop commands") exposed this bug in omap_hsmmc driver.
