2012-05-09mmc: core: Prevent eMMC VCC supply to be cut from late initUlf Hansson
For eMMC cards that has been initialized from a bootloader, the VCC voltage supply must not be cut in an uncontrolled manner, without first sending SLEEP or POWEROFF_NOTIFY. The regulator_init_complete late initcall, may cut the VCC regulator if it's reference counter is zero. To be able to prevent the regulator from being cut, mmc_start_host, which should execute at device init and thus before late init, calls mmc_power_up. Then the host driver is able to increase the reference to the regulator.

2012-05-09mmc: core: skip card initialization if power class selection failsSubhash Jadavani
With current implementation of power class selection, mmc_select_powerclass() should never fail. So treat any error returned by this function as serious enough to skip the card initialization.

2012-05-09mmc: core: fix the signaling 1.8V for HS200Seungwon Jeon
Currently only 1.2V is treated for HS200 mode. If the host has only 1.8V I/O capability not 1.2V, mmc_set_signal_voltage can't be called for 1.8V HS200. EXT_CSD_CARD_TYPE_SDR_1_8V needs to be considered.

2012-05-09mmc: core: fix the decision of HS200/DDR card-typeSeungwon Jeon
Current implementation decides the card type exclusively. Even though eMMC device can support both HS200 and DDR mode, card type will be set only for HS200. If the host doesn't support HS200 but has DDR capability, then DDR mode can't be selected.

2012-05-08mmc: mmci: Fix compiler error when CONFIG_OF is not setLee Jones
error: implicit declaration of function 'mmci_dt_populate_generic_pdata' This is due to the '#if CONFIG_OF' guards placed around mmci_dt_populate_generic_pdata(), but not around the call to it. We repair this by inserting a stub which elegantly returns when CONFIG_OF is not set.
