[v2] Correct inaccuracies in Exynos5420 and Exynos5800 device trees

[PATCH v2 0/3] Correct inaccuracies in Exynos5420 and Exynos5800 device trees

Posted by Markuss Broks 2 years, 7 months ago

Use the proper compatibles for the DSI host controller and MIPI
video phy, as the current ones are not compatible with the hardware.

While this fixes the kernel panic while trying to use DSI, I was still
unsuccessful to consistently produce image that isn't noise on S6E3FA2
panel of Samsung Galaxy S5. It seems to only work sometimes.

v1 -> v2:
- squash patch 1 and patch 3, making it one patch for adding the label and
  changing the compatible
- use better subject prefixes
