With the A80 SoC, Allwinner grouped and moved some subsystem specific
clock controls to a separate address space, and possibly separate
hardware block.
One such subsystem is the display engine. The main clock control unit
now only has 1 set of bus gate, dram gate, module clock, and reset
control for the entire display subsystem. These feed into a secondary
clock control unit, which has controls for each individual module
of the display pipeline. This block is not documented in the user
manual. Allwinner's kernel was used as the reference.
Add support for the display engine clock controls found on the A80.

Add support for the main clock unit found in the A80. Some clocks were
not documented in the released user manual, but were found in the
official kernel from Allwinner. These include controls for the I2S,
SPDIF, SATA, and eDP blocks.
Note that on the A80, some subsystems have separate clock controllers
downstream of the main clock unit. These include the MMC, USB, and
display engine subsystems.

Some extensions to the power-domain driver to support domains in
hiword registers (write-mask in upper 16bit) and domain-definitions
for the rk3328 soc.
Secondly a "driver" that attaches to the already existing grf nodes
and is able to set static defaults for settings that cannot really
be attached to any specific subsystem.
Most GRF settings can already be set from drivers using them, but there
are some behavioural settings like the mmc/jtag switch that cannot.
As the commit message states this is really meant as a last line
of defence for things that neither belong to a subsystem nor to the
Having this here allows arm64 socs to have this as well and also

The HHI_SAR_CLK_CNTL contains three SAR ADC specific clocks:
- a mux clock to choose between different ADC reference clocks (this is
2-bit wide, but the datasheet only lists the parents for the first
bit)
- a divider for the input/reference clock
- a gate which enables the ADC clock
Additionally this exposes the ADC core clock (CLKID_SAR_ADC) and
CLKID_SANA (which seems to enable the analog inputs, but unfortunately
there is no documentation for this - we just mimic what the vendor
driver does).

The current ipq4019 clock driver registered the PLL clocks and
dividers as fixed clock. These fixed clock needs to be removed
from driver probe function and same need to be registered with
clock framework. These PLL clocks should be programmed only
once and the same are being programmed already by the boot
loader so the set rate operation is not required for these
clocks. Only the rate can be calculated by clock operations
in clock driver file so this patch adds the same.
The PLL takes the reference clock from XO and generates the
intermediate VCO frequency. This VCO frequency will be divided
down by different PLL internal dividers. Some of the PLL
internal dividers are fixed while other are programmable.

The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.
