Date: Thu, 11 May 2017 16:56:23 -0700 [thread overview] Message-ID: <20170511235625.22427-3-eric@anholt.net> (raw) In-Reply-To: <20170511235625.22427-1-eric@anholt.net> The Raspberry Pi 7" Touchscreen is a DPI touchscreen panel with DSI->DPI bridge and touchscreen controller integrated, that connects to the Raspberry Pi through its 15-pin "DSI" connector (some lines are DSI, some lines are I2C). This device is represented in the DT as three nodes (DSI device, I2C device, panel). Input will be left to a separate binding later, as it will be a basic I2C client device.
