Subject: [PATCH v2 2/4] arm64: dts: ti: j722s-evm: Add MUX to control CSI2RX
Date: Thu, 8 May 2025 21:21:32 +0530	[thread overview]
Message-ID: <20250508155134.2026300-3-y-abhilashchandra@ti.com> (raw)
In-Reply-To: <20250508155134.2026300-1-y-abhilashchandra@ti.com>

J722S EVM has the CSI2RX routed to a MIPI CSI connector and to 22-pin RPi
camera connector through an analog mux with GPIO control, model that so
that an overlay can control the mux state according to connected cameras.
