Subject: [PATCH v16 5/6] dt-bindings: clock: meson: add A1 Peripherals clock controller bindings
Date:   Tue, 23 May 2023 16:53:50 +0300
Message-ID: <20230523135351.19133-6-ddrokosov@sberdevices.ru>

Add documentation and dt bindings for the Amlogic A1 Peripherals clock
controller.
A1 PLL clock controller has references to A1 Peripherals clock
controller objects, so reflect them in the schema.
