X-Git-Tag: firefly_0821_release~176^2~4117^2~4^2~5
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=661637ca2e18893b06f316dcb7907c56ea8d2904;p=firefly-linux-kernel-4.4.55.git

ARM: omap4-panda.dts: add display information

Add DT data for OMAP4 Pandaboard. The board has the following displays:

dvi: uses TFP410 encoder to convert DPI to DVI
hdmi: OMAP HDMI output with TPD12S015 ESD/level shifter
