2011-10-11mmc: block: support no access to boot partitionsAdrian Hunter
Intel Medfield platform blocks access to eMMC boot partitions which results in switch errors. Since there is no access, mmcboot0/1 devices should not be created. Add a host capability to reflect that.

2011-10-11mmc: core: eMMC 4.5 Power Class Selection FeatureGirish K S
This patch adds the power class selection feature available for mmc versions 4.0 and above. During the enumeration stage before switching to the lower data bus, check if the power class is supported for the current bus width. If the power class is available then switch to the power class and use the higher data bus. If power class is not supported then switch to the lower data bus in a worst case.

2011-10-10mmc: sd: UHS-I bus speed should be set last in UHS initializationSubhash Jadavani
mmc_sd_init_uhs_card function sets the driver type, current limit and bus speed mode on card as well as on host controller side. Currently bus speed mode is set by sending CMD6 to card and immediately setting the timing mode in host controller. But then before initiating tuning sequence, it also tries to set current limit by sending CMD6 to card which results in data timeout errors in controller if bus speed mode is SDR50/SDR104 mode. So basically bus speed mode should be set only after current limit is set in the card and immediately after setting the bus speed mode, tuning sequence should be initiated.

2011-10-10mmc: core: prevent aggressive clock gating racing with ios updatesMika Westerberg
We have seen at least two different races when clock gating kicks in in a middle of ios structure update. First one happens when ios->clock is changed outside of aggressive clock gating framework, for example via mmc_set_clock(). The race might happen when we run following code: mmc_set_ios(): ... if (ios->clock > 0) mmc_set_ungated(host); Now if gating kicks in right after the condition check we end up setting host->clk_gated to false even though we have just gated the clock. Next time a request is started we try to ungate and restore the clock in mmc_host_clk_hold(). However since we have host->clk_gated set to false the original clock is not restored. This eventually will cause the host controller to hang since its clock is disabled while we are trying to issue a request. For example on Intel Medfield platform we see: [ 13.818610] mmc2: Timeout waiting for hardware interrupt.
