All the files using printk function for displaying kernel messages
in the mmc driver have been replaced with corresponding macro.

mmc: msm_sdcc: Handle dma resource not present case

2011-10-26T19:43:37+00:00

If DMA resource is not available then SDCC driver
should atleast work in PIO data transfer mode.

mmc: msm_sdcc: Change initialization order of busclk_timer in probe

2011-10-26T19:43:37+00:00

Intialize busclk_timer before it is accessed in probe.

mmc: msm_sdcc: Use MCI_INT_MASK0 for PIO interrupts

2011-10-26T19:43:37+00:00

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.

msm: mmc: Remove "pio_irq" resource

2011-10-26T19:43:37+00:00

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.

mmc: msm_sdcc: Enable SDC host->clk only after setting the rate.

2011-10-26T19:43:37+00:00

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 change the clock rate that
is set previously.

SDC host->clk is currently enabled without setting the clock rate
even once. This patch fixes this, by ensuring that the clock rate
for this clock is first set before enabling the clock.

msm: Implement init_card operation for MSM SDCC

2011-10-26T19:43:36+00:00

This allows boards with non-standard sdio cards to fill the CIS/CCCR data.
It is particularly important for old msm72k boards using wl1251.
Also drop the obsolete embedded_sdio_data structure from the header
as it was intended to surve a similiar purpose but was not implemented.

mmc: msm_sdcc: Fix a typo in MSM SDCC driver gpio setup

gpio setup was not passed via platform data
