Subject: [PATCH 7/8] arm64: dts: allwinner: a523: Add MCU PRCM CCU node
Date: Sun, 31 Aug 2025 01:09:00 +0800 [thread overview]
Message-ID: <20250830170901.1996227-8-wens@kernel.org> (raw)
In-Reply-To: <20250830170901.1996227-1-wens@kernel.org>
From: Chen-Yu Tsai <wens@csie.org>
Add a device node for the third supported clock controller found in the
A523 / T527 SoCs. This controller has clocks and resets for the RISC-V
MCU, and others peripherals possibly meant to operate in low power mode
driven by the MCU, such as audio interfaces, an audio DSP, and the NPU.
