From 3bd0788c43d97293a4630e2f36ab31520db16a4a Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Mon, 19 Oct 2020 11:50:36 -0500 Subject: arm64: dts: imx8mm: Add support for micfil 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.
