Subject: [PATCH 0/9] mmc: sdhi: some refactoring and adding basic r8a7795 support
Date: Mon, 25 Jan 2016 20:15:07 +0100 [thread overview]
Message-ID: <1453749316-1848-1-git-send-email-wsa@the-dreams.de> (raw)
So, here is the series to enable basic SD support on r8a7795; no DMA and UHS-I
for now. Will be added incrementally. It turns out that the driver needs a
little love, so some refactoring is also in place before adding the actual
support.
eMMC works in 4-bit mode, too. 8-bit mode sadly fails currently. I'll post MMC
support patches once this issue is fixed.
These patches have been tested on Gen3 (Salvator-X) and Gen2 (Lager), doing
basic operations with SD cards and running the mmc_test driver (its results
point out some potential corner cases to check later).
A branch can be found here (including clock and DTS patches):
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/v8-sdhi
Changes since RFC (only sent to sh-devel lists):
* patches 1,7,8 are new
* patch 4 drops 10ms wait also for set_clock
* patch 9 also sets MMC_CAP_WAIT_WHILE_BUSY (see comment there)
* some commit message rewording
Please test, comment, apply...
Thanks,
Wolfram
