mmc: mxs-mmc: Fix merge issue causing build error

2012-10-11T21:21:40+00:00

The following error appeared due to a merge problem; the patches:

fc108d24 "mmc: mxs-mmc: fix deadlock caused by recursion loop"
829c1bf4 "mmc: spi: Pull out parts shared between MMC and SPI"

came in through separate branches and cause this build error when
combined.

drivers/mmc/host/mxs-mmc.c: In function 'mxs_mmc_enable_sdio_irq':
drivers/mmc/host/mxs-mmc.c:527:3: error: 'struct mxs_mmc_host' has no member named 'base'
drivers/mmc/host/mxs-mmc.c:527:3: error: 'struct mxs_mmc_host' has no member named 'devid'
make[3]: *** [drivers/mmc/host/mxs-mmc.o] Error 1

This patch corrects the issue.

Pull ARM SoC fixes from Olof Johansson:
 "A series of fixes (and in some cases, some cleanups):

  Via Tony Lindgren:
   - A collection of OMAP regression fixes, in particular because
     firmware no longer sets up all pin states before starting the
     kernel.
   - cpufreq fixes for OMAP (Rafael is on vacation and this was
     pre-agreed).
   - A longer series of misc regression fixes and cleanups, warning
     removals, etc for OMAP

  From Arnd Bergmann:
   - A series of warning fixes for various platforms (defconfig builds)

  Misc:
   - A couple of tegra fixes, one for i.MX, some vt8500 fixes, etc."

 "Core:
   - Add DT properties for card detection (broken-cd, cd-gpios,
     non-removable)
   - Don't poll non-removable devices

   - Support eMMC background operations (BKOPS).  To set the one-time
     programmable fuse that enables bkops on an eMMC that doesn't
     already have it set, you can use the "mmc bkops enable" command in:

   - eSDHC: Add ADMA support
   - sdhci: Support testing a cd-gpio (from slot-gpio) instead of
     presence bit
   - sdhci-pltfm: Support broken-cd DT property
   - tegra: Convert to only supporting DT (mach-tegra has gone DT-only)"

mmc: core: Fixup broken suspend and eMMC4.5 power off notify

2012-10-07T21:41:45+00:00

This patch fixes up the broken suspend sequence for eMMC with sleep
support. Additionally it reworks the eMMC4.5 Power Off Notification
feature so it fits together with the existing sleep feature.

The CMD0 based re-initialization of the eMMC at resume is re-introduced
to maintain compatiblity for devices using sleep.

A host shall use MMC_CAP2_POWEROFF_NOTIFY to enable the Power Off
Notification feature. We might be able to remove this cap later on,
if we think that Power Off Notification always is preferred over
sleep, even if the host is not able to cut the eMMC VCCQ power.

mmc: sdhci-spear: Add clk_{un}prepare() support

2012-10-07T21:41:45+00:00

clk_{un}prepare is mandatory for platforms using common clock framework.
Since this driver is used by SPEAr platform, which supports common clock
framework, add clk_{un}prepare() support for it.

mmc: sdhci-spear: add device tree bindings

This adds simple DT bindings for SDHCI SPEAr controller. It uses cd-gpios
from common mmc bindings.

This also fixes spear300-evb.dts with correct name for card detect binding.

mmc: core: Replace MMC_CAP2_BROKEN_VOLTAGE with test for fixed regulator

2012-10-07T21:41:43+00:00

Before this patch, we were using MMC_CAP2_BROKEN_VOLTAGE as a way to
avoid calling regulator_set_voltage() on a fixed regulator, but that's
just duplicating information that already exists -- we should test
whether the regulator is fixed directly, instead of via a capability.

This patch implements that test.  We can't reclaim the capability bit
just yet, since there are still boards in arch/arm/ that reference it;
those references can be removed now.
