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
