Fwd: [PATCH] omap5: Fix DSI base address and clocks

Sorry, meant to send this to the device tree list as well as the OMAP
one for review too.

Subject: [PATCH] omap5: Fix DSI base address and clocks
Date: Tue, 18 Aug 2020 10:51:00 +0100

DSI was not probing due to base address off by 0x1000, and sys_clk
missing.

With this patch, the Pyra display works if HDMI is disabled in the
device tree.
