The Allwinner A523 SoC introduces some new MP-style mod clock, where the
second "P" divider is an actual numerical divider value, and not the
numbers of bits to shift (1..32 instead of 1,2,4,8).
The rest of the clock is the same as the existing MP clock, so enhance the
existing code to accommodate for this.
Introduce the new CCU feature bit CCU_FEATURE_DUAL_DIV to mark an MP
clock as having two dividers, and change the dividing and encoding code
to differentiate the two cases.

So far our sunxi clock instantiation macros set the required clock
features depending on the clock type, but the new "dual divider MP
clock" requires us to pass that piece of information in by the user.
Add new wrapper macros that allow to specify a "features" field, to
allow marking those dual-divider clocks accordingly. Also add two
convenience macros that deal with the most common cases.

Some clocks in the Allwinner A523 SoC contain an "update bit" (bit 27),
which must be set to apply any register changes, namely the mux
selector, the divider and the gate bit.
Add a new CCU feature bit to mark those clocks, and set bit 27 whenever
we are applying any changes.

There is no reason to have "BIT27" in the name of the macro. This is similar
to KEY_FIELD, which is generic name and doesn't specify either key or position
of this key field. Maybe just CCU_FEATURE_UPDATE_BIT or something equaly
generic.
With that fixed:

Sure, done. This was mostly in anticipation of the typical Allwinner
behaviour of introducing another update bit at a different location in
the future. But I guess we use a bitmask should that happen.

The Allwinner A523/T527 SoCs have four CCUs, this adds the binding for
the main CCU.
The source clock list differs in some annoying details, and folding this
into the existing Allwinner CCU clock binding document gets quite
unwieldy, so create a new document for these CCUs.
Add the new compatible string, along with the required input clock
lists. This conditionally describes the input clock list, to make for
an easier patch adding the other CCUs.
Also add the DT binding headers, listing all the clocks with their ID
numbers.

I know, and I do understand the redundancy of the minItems/maxItems above,
but as I wrote in the commit message, this paves the way for the follow up
patch and makes both more readable.
Apart from helping with the review, I didn't want to conflate both devices
into one patch, I think I saw people complaining about that in the past.
If you are fine with having them both added all in one go, I am happy to
just squash the patches.
Cheers,
Andre

Put this under an allOf and use another 'if' instead of the 'else'

Ah, that's a neat idea! What do I do with the clocks and clock-names
above, then? Just have them as "true"?
Krzysztof, would you agree with this approach, and shall I still combine
both in just one patch?

The Allwinner A523/T527 SoCs have four CCUs, this adds the binding for
the PRCM R_CCU.
Add the new compatible string, along with the required input clock
lists. There is now an extra input clock (PLL_AUDIO), so add this to the
list of allowed clocks and required it for the A523 PRCM CCU.
Also add the DT binding headers, listing all the clocks with their ID
numbers.

You just added these lines in previous patch, so squash these and make a
complete binding in one patch.
Otherwise you will get comment like:

This is not supposed to be here in previous patch...

Add the PLL clocks of the main CCU of the Allwinner A523 and T527 SoCs.
The clocks were modelled after the A523 and T527 manual, and double
checked by writing all 1's into the respective register, to spot all
implemented bits.
The PLL and mod clocks for the two CPU clusters and the DSU are part of
a separate CCU, also most audio clocks are collected in a DSP CCU, so
both of these clock groups are missing from this driver.

Add the basic bus clocks for the Allwinner A523 and T527 SoCs.
This covers the AHB, APB0 and APB1 clocks. Linux is not supposed to
change those clocks, but they are needed as parents for many other mod
clocks.

devices: raw NAND flash, MMC, SPI, EMAC, "IR" infrared, and the "GPADC"
general purpose analogue/digital converter.

Add the clocks driving the USB subsystem: this just covers the two
clocks creating the 12 MHz rate for the OHCI (USB 1.x) device. The rest
of the USB clocks are either gate clocks (added later) or created
internal to the USB IP.

Add the remaining mod clocks, driving various parts of the SoC: the "LEDC"
LED controller, the "CSI" camera interface, the "ISP" image processor,
the DSP clock, and the "fanout" clocks, which allow to put clock signals
on external pins.

Add the various bus clock gates that control access to the devices'
register interface.
These clocks are each just one bit, typically the lower bits in some "BGR"
(Bus Gate / Reset) registers, for each device group: one for all UARTs,
one for all SPI interfaces, and so on.

Allwinner SoCs do not contain a separate reset controller, instead the
reset lines for the various devices are integrated into the "BGR" (Bus
Gate / Reset) registers, for each device group: one for all UARTs, one
for all SPI interfaces, and so on.
The Allwinner CCU driver also doubles as a reset provider, and since the
reset lines are indeed just single bits in those BGR register, we can
represent them easily in an array of structs, just containing the
register offset and the bit number.
Add the location of the reset bits for all devices in the A523/T527
SoCs, using the existing sunxi CCU infrastructure.

The A523/T527 SoCs have clock/reset controls in the PRCM part, like many
previous SoCs. For a change, the whole PRCM is documented in the A523
manual, including the system bus tree, so we can describe all those
clocks correctly based on that. There layout seems to be derived from
the H6 and H616 PRCM CCUs, though there are more clocks, and many clocks
have subtly changed.
Describe all the mod and gate clocks, including the three bus clocks
(R_AHB, R_APB0, and R_APB1).
