Subject: [PATCH 3/3] arm64: dts: imx8mp: Add micfil node
Date: Sun, 20 Aug 2023 12:56:55 -0500	[thread overview]
Message-ID: <20230820175655.206723-3-aford173@gmail.com> (raw)
In-Reply-To: <20230820175655.206723-1-aford173@gmail.com>

The i.MX8MP has a micfil controller which is used for interfacing
with a pulse density microphone. Add the node and mark it as
disabled by default.
