Subject: [PATCH v2 3/4] arm64: dts: ti: k3-j722s-evm: Add overlay for quad IMX219
From: Vaishnav Achath <vaishnav.a@...com>
RPi v2 Camera (IMX219) is an 8MP camera that can be used with J722S EVM
through the 22-pin CSI-RX connector. Add a reference overlay for quad
IMX219 RPI camera v2 modules on J722S EVM
