Subject: [PATCH 5/5] arm64: dts: freescale: Add common DTS overlay for IMX-AUD-IO daughter board
Date: Sat, 9 May 2026 11:48:46 +0900 [thread overview]
Message-ID: <20260509024846.2094049-6-chancel.liu@nxp.com> (raw)
In-Reply-To: <20260509024846.2094049-1-chancel.liu@nxp.com>
Add common DTS overlay for the IMX-AUD-IO daughter board[1] which
connects to the base board through a PCIe X8 slot.
This board features a CS42888 codec providing 2 microphone inputs, 2
line inputs and 6 channels audio output capability.
