From e9671ddd82eee96146a7359431a4e1f04ac2b076 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 12 Sep 2025 01:47:04 +0800 Subject: dt-bindings: clock: sun55i-a523-ccu: Add missing NPU module clock The main clock controller on the A523/T527 has the NPU's module clock. It was missing from the original submission, likely because that was based on the A523 user manual; the A523 is marketed without the NPU.

The existing binding already covers two of them that are critical for basic operation. The remaining ones are the MCU clock controller and CPU PLL clock controller. Add a description for the MCU CCU. This unit controls and provides clocks to the MCU (RISC-V) subsystem and peripherals meant to operate under low power conditions.
