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
