2012-05-17mmc: atmel-mci: change the state machine for compatibility with old IPLudovic Desroches1-116/+162
The state machine use in atmel-mci can't work with old IP versions (< 0x200). This patch allows to have a common state machine for all versions in order to remove at91-mci driver only used for old versions.

2012-05-17mmc: atmel-mci: the r/w proof capability lack was not well managedLudovic Desroches1-14/+78
First mci IPs (mainly on rm9200 and 9261) don't have the r/w proof capability. The driver didn't work correctly without this capability in PDC mode because of the double buffer switch which is too slow even if we stop the transfer to perform this switch.

2012-05-09mmc: core: Prevent eMMC VCC supply to be cut from late initUlf Hansson1-3/+15
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.

the current i.MX clock support groups together unrelated clocks to a single clock which is then used by the driver. This can't be accomplished with the generic clock framework so we instead request the individual clocks in the driver. For i.MX there are generally three different clocks: ipg: bus clock (needed to access registers) ahb: dma relevant clock, sometimes referred to as hclk in the datasheet per: bit clock, pixel clock This patch changes the driver to request the individual clocks. Currently all clk_get will get the same clock until the SoCs are converted to the generic clock framework Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
