Subject: [PATCH 4/5] arm64: dts: imx8mn: Add support for micfil
Date: Mon, 19 Oct 2020 12:45:27 -0500 [thread overview]
Message-ID: <20201019174529.289499-4-aford173@gmail.com> (raw)
In-Reply-To: <20201019174529.289499-1-aford173@gmail.com>
The i.MX8M Nano has supports the MICFIL digital interface.
It's a 16-bit audio signal from a PDM microphone bitstream.
The driver is already in the kernel, but the node is missing.
Add the micfil node.
