Subject: [PATCH v5 4/4] arm64: dts: freescale: Add dual-channel LVDS overlay for TQMa8MPxS
Date: Mon,  8 Jun 2026 16:21:33 +0200	[thread overview]
Message-ID: <20260608142144.564871-4-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20260608142144.564871-1-alexander.stein@ew.tq-group.com>

This adds an overlay for the supported LVDS display AUO G133HAN01.
Configure the video PLL frequency to exactly match typical pixel clock of
141.200 MHz.

Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>
