[PATCH 3/7] mmc: msm_sdcc: Enable SDC host-clk only after setting the rate.

For clocks that support rates which can be set (most clocks other than _pclk AHB clocks), a rate must be set using clk_set_rate() before the clock is enabled for the first time with clk_enable(). Subsequent calls to clk_enable() need not be preceded with the clk_set_rate() calls unless we wish to

[PATCH 4/7] msm: mmc: Remove pio_irq resource

On some targets, MCI_IRQ_MASK1 is not routed to the MSM in which case only cmd_irq must be used even for PIO. With this change, all the targets will use only cmd_irq for both CMD and PIO. Signed-off-by: Sahitya Tummala stumm...@codeaurora.org --- arch/arm/mach-msm/devices-msm7x00.c | 24

[PATCH 5/7] mmc: msm_sdcc: Use MCI_INT_MASK0 for PIO interrupts

Not all targets have IRQ1 line routed from the SD controller to the processor. So we cannot rely on IRQ1 for PIO interrupts. This patch moves all PIO interrupts to IRQ0 and enables the PIO mode. Signed-off-by: Murali Palnati palna...@codeaurora.org Signed-off-by: Sahitya Tummala
