Subject: [PATCH 2/3] arm64: dts: ti: k3-j721s2-main: Add audio_refclk node
Date: Mon, 12 Jan 2026 16:15:35 +0530 [thread overview]
Message-ID: <20260112104536.83309-3-m-shah@ti.com> (raw)
In-Reply-To: <20260112104536.83309-1-m-shah@ti.com>
From: Jayesh Choudhary <j-choudhary@ti.com>
On J721S2 SoC, the AUDIO_REFCLK1 can be used as input to external
peripherals when configured through CTRL_MMR.
Add audio_refclk1 node which would be used as system clock for
audio codec PCM3168A.
