From d4919a44564b1d196a4211f59250735af737031e Mon Sep 17 00:00:00 2001 From: Robert Foss Date: Tue, 24 Mar 2020 16:58:41 +0100 Subject: [PATCH] arm64: dts: qcom: sdm845-db845c: Add ov8856 & ov7251 camera nodes Enable the ov8856 main camera and the ov7251 b/w tracking camera used on the Qualcomm RB3 kit. Currently the camera nodes have not yet been attached to an to a CSI2 endpoint, since no driver currently supports the ISP that the the SDM845/db845c ships with.
