From: Adam Ford <aford173@xxxxxxxxx>
commit 24cf23276a54dd2825d3e3965c1b1b453e2a113d upstream.
A previous commit removed the panel-dpi driver, which made the
video on the AM3517-evm stop working because it relied on the dpi
driver for setting video timings. Now that the simple-panel driver
is available in omap2plus, this patch migrates the am3517-evm
to use a similar panel and remove the manual timing requirements.
Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver")
