Subject: [PATCH 0/8] arm64: allwinner: a523: Enable MCU PRCM and NPU
Date: Sun, 31 Aug 2025 01:08:53 +0800	[thread overview]
Message-ID: <20250830170901.1996227-1-wens@kernel.org> (raw)

From: Chen-Yu Tsai <wens@csie.org>

Hi folks,

This series adds support for the MCU PRCM and the NPU.

The MCU PRCM is a Power, Reset & Clock Management block that has some
clock and reset controls for the MCU, DSP and some peripherals that the
MCU could use.

The NPU is a Vivante IP block. It is clocked from the NPU PLL from the
main clock unit, but the bus clock and reset controls lie in the MCU
PRCM.

Patch 1 adds the missing NPU module clock to the main clock control
unit's binding.

Patch 2 adds the binding for the MCU PRCM clock control unit

Patch 3 fixes clock rate readback for the new dual-divider type added
with the A523 family.

Patch 4 adds the missing NPU module clock.

Patch 5 adds support for power-of-two dividers to the sunxi-ng clk
library.

Patch 6 adds a new driver for the A523 MCU PRCM CCU.

Patch 7 adds a device node for the MCU PRCM CCU.

Patch 8 adds a device node for the NPU.

The NPU was only lightly tested: the driver correctly probes and detects
a model GC9000, revision 9003.

Please have a look. All patches will be merged through the sunxi tree.


Thanks
ChenYu
