Subject: [PATCH 3/3] ARM: dts: am3517-evm: Fix missing video
Date: Wed, 28 Aug 2019 13:33:51 -0500 [thread overview]
Message-ID: <20190828183351.822-3-aford173@gmail.com> (raw)
In-Reply-To: <20190828183351.822-1-aford173@gmail.com>
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")
