[PATCH V2 00/10] mmc_of_parse() adaptations, DT support for Sheevaplugs

[Simon Baatz]

While adding DT support for the Sheevaplugs by Globalscale Technologies
(Kirkwood), it turned out that the DT binding of mvsdio lacked features to
properly support the hardware (active high/low of CD and WP pins could not
be described in DT).

This is standard functionality provided by the mmc_of_parse() helper
function.  However, mmc_of_parse() may allocate GPIO lines.  If the
allocation fails, it outputs an error, but does not return an error to its
caller.  Therefore, a proposal to handle errors in mmc_of_parse() is made.

The patch set is structured as follows:

1   Adapt mmc_of_parse() to return errors
2-6 Handle errors in current drivers using mmc_of_parse() (compile tested
    only)
7-8 Convert mvsdio and respective dts files to mmc_of_parse() (tested on
    kirkwood)
9   Add dts files for (eSATA) Sheevaplug
10  Add DT support for (eSATA) Sheevaplug


I could only test on an eSATA Sheevaplug. I found patches with
different LEDs for the Sheevaplug.  Thus, I would highly appreciate if
someone with the hardware could give this a spin on a non-eSATA
version.  Some additional testing of the change detect and write
protect behaviour for mvsdio can't hurt either.  I hope that there aren't
board revisions with different CD/WP pins out there.

Simon Baatz (10):
  mmc: return mmc_of_parse() errors to caller
  mmc: sh_mmcif: handle mmc_of_parse() errors during probe
  mmc: tmio-mmc: handle mmc_of_parse() errors during probe
  mmc: mxcmmc: handle mmc_of_parse() errors during probe
  mmc: sdhi-pxav3: handle mmc_of_parse() errors during probe
  mmc: tegra: handle mmc_of_parse() errors during probe
  ARM: mvebu: Use standard MMC binding for all users of mvsdio
  mmc: mvsdio: use standard MMC device-tree binding parser
    mmc_of_parse()
  ARM: Kirkwood: Add dts files for Sheevaplug and eSATA Sheevaplug
  ARM: Kirkwood: add DT support for Sheevaplug and Sheevaplug eSATA
