Hi,
Dne petek, 16. marec 2018 ob 15:02:13 CET je Icenowy Zheng napisal(a):
> The Allwinner H6 SoC has a CCU which has been largely rearranged.
>
> Add support for it in the sunxi-ng CCU framework.
>
> Signed-off-by: Icenowy Zheng <icenowy at aosc.io>
> Acked-by: Maxime Ripard <maxime.ripard at bootlin.com>
> ---
> Changes in v4:
> - Extract the device tree binding document to another patch.
>
> Changes in v3:
> - SPDX license idetifier fix.
> - Add some comments at initialization.
>
> Changes in v2:
> - Exported APB1 bus clock for PIO.
> - Switch to SPDX license identifier.
