2017-02-13mmc: sdio: don't use rocr to check if the card could support UHS modeShawn Lin1-7/+17
Per SDIO Simplified Specification V3, section 3.1.2, A host that supports UHS-I sets S18R to 1 in the argument of CMD5 to request a change of the signal voltage to 1.8V. If the card supports UHS-I and the current signal voltage is 3.3V, S18A is set to 1 in the R4 response. If the signal voltage is already 1.8V, the card sets S18A to 0 so that host maintains the current signal voltage. UHS-I is supported in SD mode and S18A is always 0 in SPI mode. For the current code, if the signaling voltage is fixed 1.8v, so the card will set S18A to 0 for rocr and thus we would clear the R4_18V_PRESENT from ocr, which make core won't try to use uhs mode. To fix it, we expect sdio_read_cccr would fail if the uhs mode won't work at all. Note that it's interesting that some sdio cards still response S18A even the voltage is fixed to 1.8v and the CMD11 will also accepted and finish enabling UHS mode successfully. I guess this is why folks didn't notice this problem. Anyway, fix it. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2017-02-13mmc: sdhci-of-esdhc: remove default broken-cd for ARMyangbo lu1-8/+10
Initially all QorIQ platforms were PowerPC architecture and they didn't support card detection except several platforms. The driver added the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION as default and this made broken-cd property in dts node didn't work. Now QorIQ platform turns to ARM architecture and most of them could support card detection. However it's a large number of dts trees that need to be fixed with broken-cd if we remove the default SDHCI_QUIRK_BROKEN_CARD_DETECTION in driver. And the users don't want to see this. So this patch is to remove this default quirk just for ARM and keep it for PowerPC.(Note, QorIQ PowerPC platform only has big-endian eSDHC while QorIQ ARM platform has big-endian or little-endian eSDHC) This makes broken-cd property work again for ARM.

2017-02-13mmc: use empty initializer list to zero-clear structuresMasahiro Yamada10-73/+73
In the MMC subsystem, we see such initializers that only clears the first member explicitly. For example, struct mmc_request mrq = {NULL}; sets the first member (.sbc) to NULL explicitly. However, this is an unstable form because we may insert a non-pointer member at the top of the struct mmc_request in the future. (if we do so, the compiler will spit warnings.) So, using a designated initializer is preferred coding style. The expression above is equivalent to: struct mmc_request mrq = { .sbc = NULL }; Of course, this does not express our intention. We want to fill all struct members with zeros. Please note struct members are implicitly zero-cleared unless otherwise specified in the initializer. After all, the most reasonable (and stable) form is: struct mmc_request mrq = {}; Do likewise for mmc_command, mmc_data as well.
