[PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

[Dan MacDonald]

I think the easiest (if definitely not the fastest) way for me to test
these patches the Arch way

IF

they will apply cleanly against 4.11-rc1 is to patch the
linux-armv7-rc PKGBUILD so that it will apply Phillipp's patches
before it builds the kernel.

The linux-armv7-rc PKGBUILD is available from

git clone https://github.com/archlinuxarm/PKGBUILDs.git

under core/linux-armv7-rc. I think all I should need to do is add:

git fetch https://git.pengutronix.de/git/pza/linux.git
tags/v4.10-ipu-dp-plane-fix
git checkout FETCH_HEAD

To the prepare() section of the PKGBUILD, prob just after the last
`git apply ...` line

Should your patches work fine under 4.11-rc1 Phillipp or do I need to
test againt the very latest git? I realise that would be preferred.

If anyone can tell me how I would build linux git specifically for
Arch on the SABRE Lite, that'd be even better! I haven't needed to
build a kernel in a very long time!

Thanks
