The MMCIF and SHDI platform data .set_pwr() callbacks are used to
control the vmmc/vqmmc power supplies. As the power supplies already
register control GPIOs there's no need to perform the operation
manually. Remove the callback functions.

Add support for passing CD/RO GPIO numbers directly to the mmc_spi
driver instead of relying solely on board code callbacks to retrieve the
CD/RO signals values. The driver will enable debouncing on the card
detect GPIO if the cd_debounce field is set to a non-zero value.

I'm testing SH-Mobile SDHI driver in DMA mode with  a new DMA controller  using
'bonnie++' and getting DMA error after which the tmio_mmc_dma.c code falls back
to PIO but all commands time out after that.  It turned out that the fallback
code calls tmio_mmc_enable_dma() with RX/TX channels already freed and pointers
to them cleared, so that the function bails out early instead  of clearing the
DMA bit in the CTL_DMA_ENABLE register. The regression was introduced by commit
162f43e3 (mmc: tmio: fix a deadlock).
Moving tmio_mmc_enable_dma() calls to the top of the PIO fallback code in
tmio_mmc_start_dma_{rx|tx}() helps.

A previous commit (fdfa20c1) reordered the shutdown sequence
in mmc_blk_remove_req. However, mmc_cleanup_queue is now called before
we get the card pointer, and mmc_cleanup_queue sets mq->card to NULL.

This patch moves the card pointer assignment before mmc_cleanup_queue.

The usage of strict_strtol() is not preferred, because

omap_hsmmc.c depends on <linux/sizes.h> being included indirectly by
another header. Once we enable COMPILE_TEST for this driver, we might
compile under architectures which won't include <linux/sizes.h> for us.
In fact, one such case is x86.

In order to prevent compile breakages, let's explicitly include

Current MMC driver doesn't handle generic error (bit19 of device
status) in write sequence. As a result, write data gets lost when
generic error occurs. For example, a generic error when updating a
filesystem management information causes a loss of write data and
corrupts the filesystem. In the worst case, the system will never
boot.

This patch includes the following functionality:
  1. To enable error checking for the response of CMD12 and CMD13
     in write command sequence
  2. To retry write sequence when a generic error occurs

Messages are added for v2 to show what occurs.

Generally request_irq() should be called after hardware has been
initialized into a sane state.  However, sdhci driver currently calls
request_irq() before sdhci_init().  At least, the following kernel panic
seen on i.MX6 is caused by that.  The sdhci controller on i.MX6 may have
noisy glitch on DAT1 line, which will trigger SDIO interrupt handling
once request_irq() is called.  But at this point, the SDIO interrupt
handler host->sdio_irq_thread has not been registered yet.  Thus, we
see the NULL pointer access with wake_up_process(host->sdio_irq_thread)
in mmc_signal_sdio_irq().

Fix the panic by simply reverse the calling sequence between
request_irq() and sdhci_init().

stmp_reset_block() may fail, so let's check its return value and
propagate it in the case of error.

Using devm_clk_get() allows us to remove the clk_put() calls, so
let's use it to simplify the code.

Rename the 'out_clk_put' label to 'out_clk_disable' now that clk_put
is removed.

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR(). Also there is already a error message within
devm_ioremap_resource(), so remove the dev_err call to avoid redundant
error message.

     driver.
   - RTL8411B support from the rtsx driver.
