1. Add S4 SoC PLL and Peripheral clock controller dt-bindings.
2. Add PLL and Peripheral clock controller driver for S4 SOC.
Yu Tu (4):
dt-bindings: clock: document Amlogic S4 SoC PLL clock controller
dt-bindings: clock: document Amlogic S4 SoC peripherals clock
controller
clk: meson: S4: add support for Amlogic S4 SoC PLL clock driver
clk: meson: s4: add support for Amlogic S4 SoC peripheral clock
controller
V6 -> V7: Change send patch series as well change format and clock flags
suggested by Jerome. Change dt-bindings suggested by Krzysztof.
V5 -> V6: Change send patch series, as well change format and clock flags.
V4 -> V5: change format and clock flags and adjust the patch series
as suggested by Jerome.
V3 -> V4: change format and clock flags.
V2 -> V3: Use two clock controller.
V1 -> V2: Change format as discussed in the email.

Jerome currently has very limited time so I'll be trying to continue
with the code-review.
Unfortunately I am running out of time for today, so please give me a
few more days to review your patches.
Thanks four your patience!
Best regards,
Martin

As per my understanding, Meson is no longer applicable.
As Neil and Martin suggested in other reviews, the term 'Amlogic' should
be used instead or 'Meson' should be removed altogether.

I was under the impression that reg as MMIO address should have four
cells on ARM64 architecture. Are you sure it only needs two cells?

I believe that the CLK suffix is unnecessary since it is already clear
that the object in question is a clock. Additionally, it is redundant
to use the GATE suffix.

In my opinion, all clocks that can inherit from a more accurate RTC clock
should be marked with the CLK_SET_RATE_NO_REPARENT flag.
This is necessary because in certain situations, it may be required to
freeze their parent. The setup of these clocks' parent should be located
on the device tree's side.

I think, the gen_clk selector should be marked with the
CLK_SET_RATE_NO_REPARENT flag. This is because the GEN clock can be
connected to an external pad and may be set up directly from the
device tree.

Yes. Maybe you can check out the clock file for other yaml.The two cells
and four cells all are ok.
It's not a problem even in real DTS. How many cells are needed to look
at the parent address-cells and size-cells definitions.

No. These prefixes and suffixes are very friendly to the people who
write and read the code.

We don't need to freeze parent,in a real project.

In my opinion, an RTC clock is more accurate and its rate can be
adjusted to a specific value. If I choose the RTC clock as the parent,
I don't want to run the rate auto-propagation for the child clock.
Otherwise, the parent can be changed to fit a specific frequency.

Sorry, I do not currently have the Y4 datasheet available.
Previously, the GEN_CLK was muxed to the GPIO on specific boards,
depending on the board layout, and I referred to this situation as
'connect to external pad'.
Therefore, I believe it would be more efficient to have the ability to
freeze the GEN_CLK parent and rate.

Okay, it seems like there may be a misunderstanding here.
Now might be a good time to ask Neil about the correct behavior.
Neil, could you please provide the specific naming rules for the new
Amlogic drivers? Where should we use the 'meson' keyword, and where
should we not use it?

AFAIR, it depends on which OF API you will call for retreive address
and size values (u32 or u64).

Jerome has already pointed this out in another review for the
A1 clock driver, there are redundant suffixes:

I think, reference to one time mentioned comment is clear for viewer too.
Also Jerome has pointed to this problem for the A1 driver as well:

drivers, and some overlaps were found.
I just want to help you find potential problems.

At least you are requesting the ioremap resource, right? :-)
And clock driver has tristate config, so can be built as module.

The current goal is to first get rid of meson in the compatiob, which is ok here,
then remove meson in the driver name & function names, and then wherever it's a
nice to have to remove meson in bindings & comments.
So if you where sending a v8, it would be good to remove the Meson in the
bindings description.

Again, Dmitry remark is very interresting.
This debug clock is typacally one you don't really want to automatically reparent
