Subject: [PATCH v5 1/2] dt-bindings: ti: Update audio-refclk binding and j721e system controller
Date: Wed, 20 May 2026 17:26:02 +0530 [thread overview]
Message-ID: <20260520115603.2662930-2-m-shah@ti.com> (raw)
In-Reply-To: <20260520115603.2662930-1-m-shah@ti.com>
Add ti,j721s2-audio-refclk as a supported compatible string in the
ti,am62-audio-refclk binding. J721S2 uses the same audio reference
clock IP block first introduced on AM62. Per writing-bindings
guidelines, the J721S2-specific compatible is added as the primary
string with ti,am62-audio-refclk as the fallback.
Also extend the ti,j721e-system-controller clock-controller@ child
pattern to accept audio-refclk schemas alongside ehrpwm-tbclk via a
oneOf constraint.
