[PATCH v6 0/8] clk: sunxi-ng: Add support for Allwinner A733 CCU and PRCM

[Vinicius Pedrosa]

Hi Junhui,

I tested v6 on a Radxa Cubie A7Z (A733, 1 GiB LPDDR4), Linux 7.3-rc6
with the eight patches as posted. On top of that I have Andre's pinctrl,
Enzo's DT work and my local DT/UART/pinctrl changes. TF-A and U-Boot are
built from source, with local changes; boot0 and SCP are still the vendor
ones.

It cold boots from microSD to systemd with 8 CPUs, with the unused-clock
cleanup active and no clk_ignore_unused.

About ahb-store without CLK_IS_CRITICAL: clk_summary showed mmc0,
bus-mmc0 and ahb-store disabled at idle, enabled during O_DIRECT reads,
and disabled again afterwards, over three cycles. The hashes matched,
and there were no MMC or clock errors in the logs. mbus-store stayed on.

A native PSCI reboot also worked without the local critical flags on
bus-r-riscv and bus-r-msgbox, and the data was intact afterwards.

These tests cover boot, MMC and reboot on this board, not all clocks,
resets or secure boot.
