Currently DT compatibility strings of both types can be found in the kernel
sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be
followed and the former one is preferred. This patch converts the SDHI
MMC driver and its users to the common standard. This is safe for now, since
ATM no real products are using this driver with DT.

Pull MMC updates from Chris Ball:
"MMC highlights for 3.12:
Core:
- Support Allocation Units 8MB-64MB in SD3.0, previous max was 4MB.
- The slot-gpio helper can now handle GPIO debouncing card-detect.
- Read supported voltages from DT "voltage-ranges" property.
Drivers:
- dw_mmc: Add support for ARC architecture, and support exynos5420.
- mmc_spi: Support CD/RO GPIOs.
- sh_mobile_sdhi: Add compatibility for more Renesas SoCs.
- sh_mmcif: Add DT support for DMA channels"

OMAP's hs_mmc driver is used for MMC controller operation on many
omap2plus SoCs (OMAP2430, OMAP3, 4, 5 and AM335x).
Considering that the device tree entries are already present for these,
allow the driver to be built using the config ARCH_OMAP2PLUS rather
than individually adding a config for each SoC to enable the
support.
Use COMPILE_TEST to enable the build for other platforms.

Commit 1f6b9fa40e76fffaaa0b3bd6a0bfdcf1cdc06efa consolidated writes to
the STAT register in one location, moving them from omap_hsmmc_do_irq()
to omap_hsmmc_irq(). This move has the unwanted side effect that the
controller status flags are potentially cleared after a new command has
been started as a consequence of reading the previous status flags.
This means that if the new command changes the status flags before the
IRQ routine returns, those flags may be cleared without handling the
event which asserted them, and thus missing the event.
Move the writing of the STAT register back in omap_hsmmc_do_irq(),
before handling the status flags which generated the interrupt.

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
162f43e31c5a376ec16336e5d0ac973373d54c89 (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.

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().

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.

Pull MFD (multi-function device) updates from Samuel Ortiz:
"For the 3.12 merge window we have one new driver for the DA9063 PMIC
from Dialog Semiconductor.
Besides that driver we also have:
- Device tree support for the s2mps11 driver
- More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
wl1273 and pcf50633-adc drivers.
- A conversion to threaded IRQ and IRQ domain for the twl6030 driver.
- A fairly big update for the rtsx driver: Better power saving
support, better vendor settings handling, and a few fixes.
- Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
Kontron driver.
- A conversion to the dev_get_platdata() API for all MFD drivers.
- A removal of non-DT (legacy) support for the twl6040 driver.
- A few fixes and additions (Mic detect level) to the wm5110 register
tables.
- Regmap support for the davinci_voicecodec driver.
- The usual bunch of minor cleanups and janitorial fixes"
