      arm/dt: Fix ventana SDHCI power-gpios · c406eeb3
      由 Stephen Warren 提交于 
      Ventana uses the same SDHCI GPIOs as Seaboard; PI6 (70) is the power GPIO
for the SD port, and there is no power GPIO for the MMC chip.

      arm/tegra: Don't create duplicate gpio and pinmux devices · 4b91b6fb
      由 Stephen Warren 提交于 
      *_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.

*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.

To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.

Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.

This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:

a) Initializing the HW state from DT nodes during GPIO and pinmux device
   probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
   their probe until after the gpio and pinmux drivers have probed.

v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.

      arm/mxs: fix mmc device adding for mach-mx28evk · e94e05ea
      由 Shawn Guo 提交于 
      The merge commit "526b2641 Merge branch 'imx/cleanup' into imx/devel"
left a duplicated mx28_add_mxs_mmc() call, which causes the problem
below during boot.

  kobject_add_internal failed for mxs-mmc.1 with -EEXIST, don't try
  to register things with the same name in the same directory.

The patch removes this leftover and also change mmc0 adding to align
with mmc1.

      ARM: OMAP: Fix export.h or module.h includes · a1bcc1dc
      由 Tony Lindgren 提交于 
      Commit 32aaeffb (Merge branch
'modsplit-Oct31_2011'...) caused some build errors. Fix these
and make sure we always have export.h or module.h included
for MODULE_ and EXPORT_SYMBOL users:

$ grep -rl ^MODULE_ arch/arm/*omap*/*.c | xargs \
  grep -L linux/module.h
  arch/arm/mach-omap2/dsp.c
  arch/arm/mach-omap2/mailbox.c
  arch/arm/mach-omap2/omap-iommu.c
  arch/arm/mach-omap2/smartreflex.c

Also check we either have export.h or module.h included
for the files exporting symbols:

$ grep -rl EXPORT_SYMBOL arch/arm/*omap*/*.c | xargs \
  grep -L linux/export.h | xargs grep -L linux/module.h

      arm: Add export.h to recently added files for EXPORT_SYMBOL · 0c073e35
      由 Paul Gortmaker 提交于 
      These files didn't exist at the time of the module.h split, and
so were not fixed by the commits on that baseline.  Since they use
the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the
new export.h file included that provides them.
