From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Hi, These add support for DSI on V4H SoC (r8a779g0) and DP for Whitehawk board. Changes in v2: - A few cosmetic changes - Increase vspd address range in dts to 0x7000 - Arrange nodes in dts by the block address - Use gen = 4 for r8a779g0 du - Drop the CLOCKSET1 hack patch The CLOCKSET1 patch is apparently not needed to get the DSI & DP working. Which is baffling, as I'm quite sure it was needed. There are a few possible explanations: 1) it was never needed and I was just messing things up, 2) it was needed, but some of my later improvements made it unnecessary, 3) Whitehawk board firmware was updated in the middle of the development of this series, possibly the firmware made the patch unnecessary.
