[PATCH V8 00/14] drm/exynos: few patches to enhance bridge chip support

[Ajay kumar]

Hi Javier,

In the cover letter, I have mentioned that it is tested on Linus tree:

"This series is based on master branch of Linus tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git"

Kindly test the patches with that.

Ajay
