Subject: [PATCH V3 4/5] arm64: dts: imx8mn: Add support for micfil
Date: Fri, 6 Nov 2020 05:15:42 -0600 [thread overview]
Message-ID: <20201106111543.1806809-4-aford173@gmail.com> (raw)
In-Reply-To: <20201106111543.1806809-1-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.
