Subject: [RFC PATCH 6/6] ARM: dts: keystone-k2g-evm: add LCD and HDMI displays
Date: Thu, 31 May 2018 15:41:09 +0300 [thread overview]
Message-ID: <20180531124109.3209-7-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20180531124109.3209-1-tomi.valkeinen@ti.com>
K2G EVM has an SiI902x HDMI encoder on the board, and a separately
purchasable LCD which can be attached to the board. Only one of these
displays can be used at a time, and two dip-switches need to be changed
when switching to another display.
The HDMI support is added to the base k2g-evm.dts file, and the LCD
support is added as a separate k2g-evm-lcd.dts file. The user must
choose one of the dtbs, depending on which display he wants to use.
