Subject: [PATCH V2 1/3] arm64: dts: imx8mm: Add support for micfil
Date: Mon, 19 Oct 2020 11:50:36 -0500 [thread overview]
Message-ID: <20201019165038.274164-1-aford173@gmail.com> (raw)
The i.MX8M Mini 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.
This patch adds the micfil node.
