Batch conversion of the following bindings:
- rtc-meson-vrtc.txt
- amlogic,gxbb-clkc.txt
- amlogic,gxbb-aoclkc.txt
- clk-measure.txt
And in addition document the System Control registers top node.
DT fixups will be posted once those conversion are fully reviewed.
With this serie, the in-review and applied bindings documentation, the
the following arm64 compatible are yet to be documented in dt-schema:
['amlogic,axg-audio-clkc']
['amlogic,g12a-audio-clkc']
['amlogic,sm1-audio-clkc']
['amlogic,g12a-tohdmitx']
['amlogic,sm1-tohdmitx', 'amlogic,g12a-tohdmitx']
['everest,es7154']
['everest,es7241']
['ti,tas5707']
['linux,spdif-dir']
['gpio-fan']
['pwm-fan']

2.34.1
Document the System Control registers regions found on all Amlogic
SoC families and it's clock, power, pinctrl and phy subnodes.
The regions has various independent registers tied to other
hardware devices, thus the syscon compatible.
Clock controllers and Pinctrl devices are not yet documented, the
definition of those will be updated in a second time.

Since the clock controllers are now documented define the right ref
for the clock-controller subnodes and fill up the example node.

It's been there in the old bindings as well but it would be great to
have it fixed.

I understand clock (main clock controller) power (power domain
controller) and PHY (HDMI and CVBS PHYs). Are you sure about pinctrl?

If you have to re-send this then it would be great if you could add:
- amlogic,meson-hhi-sysctrl
because we already have that in arch/arm/boot/dts/meson.dtsi for the
32-bit SoCs.

For this node (and similar ones) I have a question to the device-tree
maintainers:
The power controller has a dedicated sub-range of registers. This also
applies to the CVBS and HDMI PHYs.
But the clock controller does not (it has its registers all over the
place - unfortunately that's how the hardware is).
I have been asked to add a "reg" property to child nodes with a
sub-register space.
Does this mean we need to add a reg property here as well (regardless
of whether we're using it in the driver or not)? And what to do in
case of the clock controller though?
Best regards,
Martin

And all other variants? This allows phy/power/pinctrl/clock in any
combination, thus maybe the binding should be just split? Hard to say
without full picture.

The example should be complete, so empty node does not look correct. If
you wait for other bindings, send them as patchset when all are ready.

Drop the parent node, not needed here. You could even skip the example
entirely as it is part of your syscon. If you keep example, then without
parent pieces.

It's a chicken and egg problem, the clock controller bindings (patches 4 & 6)
I've added the system-controller top node in the DT example, but this
example won't be valid until I add the system-controller bindings.
To solve this, I add it in 2 steps, but if it's an *real* issue I can remove
the top system-controller nodes in the clock controller bindings and add them
later on and add the sysctrl bindings in one step.

Just drop the parent node or even entire example.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.4/drivers)
[2/6] dt-bindings: soc: amlogic: convert clk-measure.txt to dt-schema
https://git.kernel.org/amlogic/c/2227e738b30bf20380a48391a73752c52f5f5c6a
These changes has been applied on the intermediate git tree [1].
The v6.4/drivers branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.
In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].
The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.
If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
