Subject: [PATCH 2/8] dt-bindings: clock: clocking-wizard: Make reg optional for static-config
Date: Mon, 15 Jun 2026 09:18:39 +0530	[thread overview]
Message-ID: <20260615034845.3320286-3-shubhrajyoti.datta@amd.com> (raw)
In-Reply-To: <20260615034845.3320286-1-shubhrajyoti.datta@amd.com>

In static-config mode the IP exposes only fixed-factor clock outputs and
has no runtime-programmable registers, so reg is not required.
