Bug#749484: linux: Please backport Cubietruck (sunxi) MMC driver/dt
Package: linux
Version: 3.15~rc5-1~exp1
Severity: wishlist
Dear Maintainer,
(I've already discussed this with ijc on IRC, but...)
Please consider backporting the MMC / SD driver for the
Cubietruck (sunxi) board. This driver is the last missing
piece to have a usable kernel for a headless system.
The MMC driver has gone through many iterations of review
on the linux-arm-kernel mailing list and should now be
sitting in maintainers trees waiting for the 3.16 merge
window to open.

I've gathered a list of commits I think are the ones you'll need.
First two patches in Mike Turquettes clk-next branch:
https://git.linaro.org/people/mike.turquette/linux.git/commitdiff/862b728387aef3a3776ad2a261e484aff36c5e67
https://git.linaro.org/people/mike.turquette/linux.git/commitdiff/95713978b0a2929b72933235bb07c0a793e71afa
The actual driver is in Ulf Hanssons "mmc-next_for_chris_3.16_take3" branch:
https://git.linaro.org/people/ulf.hansson/mmc.git/commitdiff/f3f0976c92e0ce5b93bc64d231dce096045a44f7
DeviceTree patches in Maxime Ripards "dt-for-3.16" branch
(all of these should also be available in the arm-soc tree):

(Not mmc related, but was part of same review thread and also something we
want if we don't already have it...)
https://github.com/mripard/linux/commit/3906c0a688587408fa37a411d5e79778039e9dc3
(These additional changes on top of the mailing list thread looks like
they are also needed because of final review driver changes...)

(and a last minute fixup...)
https://github.com/mripard/linux/commit/c5b7261cae14ada86f5823659664fade0bcefa20
Maybe also needed:
https://github.com/mripard/linux/commit/5b9c49bea11ac5a02deeda1b737f02c5865243e5
Finally, the sunxi driver(s) needs to be enabled in the config
(as apparently the defconfig hasn't been updated according to the G+ post
linked to above.)
