Subject: Re: [PATCH v8 02/17] drm: bridge: analogix/dp: split exynos dp driver
 to bridge directory

Hi Heiko,

Thanks you for feedback, I do see some conflicts in Exynos Make/Kconfig
file [02/17] and dtsi file [07/17] when I try to apply this series on 
4.4-rc1
branch.

Hmm... Due to I have update some patches to version 10 already, this
series may be become harder to reviewed, should I just send the whole
series out that update the version to v10.

Thanks
- Yakir
