Changes v1 -> v2:
- Detached from v1's series (patch 2, 3, 4, 25).
- Reuse some of defines from axg-audio;
- Split the controller into two memory regions.
Jan Dakinevich (5):
clk: meson: axg: move reset controller's code to separate module
clk: meson: axg: share the audio helper macro
dt-bindings: clock: meson: document A1 SoC audio clock controller
driver
clk: meson: a1: add the audio clock controller driver

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

In general, I like the idea.
We do have a couple a reset registers lost in middle of clocks and this
change makes it possible to re-use the code instead duplicating it.
The exported function would be used by audio clock controllers, but the
module created would be purely about reset.
One may wonder how it ended up in the clock tree, especially since the
kernel as a reset tree too.
I'm not sure if this should move to the reset framework or if it would
be an unnecessary churn. Stephen, Philipp, do you have an opinion on
this ?

Could expand a bit please ?

In general, I like the idea.
We do have a couple a reset registers lost in middle of clocks and this
change makes it possible to re-use the code instead duplicating it.
The exported function would be used by audio clock controllers, but the
module created would be purely about reset.
One may wonder how it ended up in the clock tree, especially since the
kernel as a reset tree too.
I'm not sure if this should move to the reset framework or if it would
be an unnecessary churn. Stephen, Philipp, do you have an opinion on
this ?

I think you already got that comment but audio2 is a terrible name.
Given that the 2nd controller is mostly about VAD (PDM is there only to
feed it) and that it is just a name, I'd prefer something like a1_audio_vad.

Why do you have to do that and cannot do it like the rest of the

That is really over-complicated for what it does ....

It does not make a lot of sense that one of the 2 controllers as 2nd
pclk.
You should consider using the AUD2_CLKID_AUDIOTOP as a parent of audio
gates instead. You would not have to that.

Again this is over-complicated.
Just make an external function for the register, use it for axg, a1,
a1-vad, then make one file for each controller. That will keep the code
clean and readable.
keep it simple please.

I think you already got that comment but audio2 is a terrible name.
Given that the 2nd controller is mostly about VAD (PDM is there only to
feed it) and that it is just a name, I'd prefer something like a1_audio_vad.

Why do you have to do that and cannot do it like the rest of the
modules ?

That is really over-complicated for what it does ....

It does not make a lot of sense that one of the 2 controllers as 2nd
pclk.
You should consider using the AUD2_CLKID_AUDIOTOP as a parent of audio
gates instead. You would not have to that.

Again this is over-complicated.
Just make an external function for the register, use it for axg, a1,
a1-vad, then make one file for each controller. That will keep the code
clean and readable.
keep it simple please.

I think you already got that comment but audio2 is a terrible name.
Given that the 2nd controller is mostly about VAD (PDM is there only to
feed it) and that it is just a name, I'd prefer something like a1_audio_vad.

Why do you have to do that and cannot do it like the rest of the
modules ?

That is really over-complicated for what it does ....

It does not make a lot of sense that one of the 2 controllers as 2nd
pclk.
You should consider using the AUD2_CLKID_AUDIOTOP as a parent of audio
gates instead. You would not have to that.

Again this is over-complicated.
Just make an external function for the register, use it for axg, a1,
a1-vad, then make one file for each controller. That will keep the code
clean and readable.
keep it simple please.

It's a bit unclear here. Is this a general recommendation or is it
specific to _this_ location in the code?
> Just make an external function for the register
Dou you suggest to share something like a1_register_clk()? Currently, it
is not good idea, axg-audio uses slightly different way to register
their clocks.

It's a bit unclear here. Is this a general recommendation or is it
specific to _this_ location in the code?
> Just make an external function for the register
Dou you suggest to share something like a1_register_clk()? Currently, it
is not good idea, axg-audio uses slightly different way to register
their clocks.

It's a bit unclear here. Is this a general recommendation or is it
specific to _this_ location in the code?

Dou you suggest to share something like a1_register_clk()? Currently, it
is not good idea, axg-audio uses slightly different way to register
their clocks.

I'd prefer it be made into an auxiliary device and the driver put in
drivers/reset/ so we can keep reset code in the reset directory. The
auxiliary device creation function can also be in the drivers/reset/
directory so that the clk driver calls some function to create and
register the device.

Seconded, the clk-mpfs/reset-mpfs and clk-starfive-jh7110-sys/reset-
starfive-jh7110 drivers are examples of this.

I'm undecided about this, do you think mpfs_reset_controller_register()
and jh7110_reset_controller_register() should rather live with the
reset aux drivers in drivers/reset/ ?

Yes, and also mpfs_reset_read() and friends. We should pass the base
iomem pointer and parent device to mpfs_reset_adev_alloc() instead and
then move all that code into drivers/reset with some header file
exported function to call. That way the clk driver hands over the data
without having to implement half the implementation.

Thanks a lot for the example Conor !
When it comes to Amlogic, I think the bits of reset instanciated by
clock drivers could probably share (part of) the code of the existing
amlogic reset driver. Some have toggle only, no level, but it is mostly
the same.
I'll try to have a look at it

I suppose, really I was just being "lazy" here and creating a global
rather than a `struct mpfs_reset` containing only the base address.
The test robot reported some issues with hexagon & COMPILE_TEST, so I'll
push it out again with this change and the fixes for the reported issues
and send the patch ones it gets the all clear.
Cheers,
Conor.

I suppose, really I was just being "lazy" here and creating a global
rather than a `struct mpfs_reset` containing only the base address.
The test robot reported some issues with hexagon & COMPILE_TEST, so I'll
push it out again with this change and the fixes for the reported issues
and send the patch ones it gets the all clear.
Cheers,
Conor.
