Hello,
This mini-series adds initial support for the Realtek RTD1295 SoC and
the Zidoo X9S TV box.
With these patches CPU0 can be booted with earlycon.
PSCI doesn't work despite present in the vendor device tree; as enable-method
it instead used a custom "rtk-spin-table" that I sadly have no sou
Now that we have support for the A83T CCU, add a device node for it,
and replace any existing placeholder clock phandles with the correct
ones.

The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.
The mmc2 module clock supports a new timing mode. This mode outputs the
clock at half the set rate, and moves the output and sample delays into
the mmc controll
Some clock gates have a pre-divider between the source input and the
gate itself. A notable example is the HSIC 12 MHz clock found on the
A83T, which has the 24 MHz main oscillator as its input, and a /2
pre-divider.

The MP style clocks support an mux with pre-dividers. While the driver
correctly accounted for them in the .determine_rate callback, it did
not in the .recalc_rate and .set_rate callbacks.
This means when calculating the factors in the .set_rate callback, they
would be off by a factor of the activ

Hi everyone,
This is yet another series that adds support for the A83T CCU.
The A83T CCU has a mix of new styled (like the A80) clocks at
old (like A3x) offsets. Some differences include:
- D1/D2 style PLL clocks
- divisible audio module clocks
- new timing mode for mmc2 module clock
