Hi,
V3 changes:
- Patch 01/10: Added EPROBE_DEFER case to mmc_of_parse()
- Added Acked-By to (unmodified) patches 02 and 03.
V2 changes:
- Converted mvsdio to use mmc_of_parse()
- Adapted DTS files using mvsdio accordingly
- Changed mmc_of_parse() to return errors to the caller
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.
