The original patch series "Basic StarFive JH7110 RISC-V SoC support" [1]
is split into 3 patch series. They respectively add basic clock&reset,
pinctrl and device tree support for StarFive JH7110 SoC. These patch
series are independent, but the Visionfive2 board can boot up successfully
only if all these patches series applied. This one adds basic clock&reset
support. This patch series is pulled out from the patch 7~21 of v1 [1].
You can simply get or review the patches at the link [2].

Changes since v1:
- Rebased on tag v6.1-rc5.
- Rewrote the clock and reset drivers using auxiliary bus framework, so
patch 8, 9, 15 were dropped and all patches changed a lot. (by Stephen)
- Split Patch 14 into two patches. One is for factoring out the common
JH71X0 code, the another one is for renaming. (by Stephen)
- Created a subdirectory for StarFive reset drivers.
- Factored out common JH71X0 reset code.
- Renamed the common clock and reset code from "*starfive*" or
"*STARFIVE*" to "*jh71x0*" or "*JH71X0*".
- Combined JH7110 system and always-on clock DT binding headers in one
file named "include/dt-bindings/clock/starfive-jh7110.h".
- Renamed clock definitions "JH7110_SYSCLK_PCLK2_MUX_FUNC_PCLK" and
"JH7110_SYSCLK_U2_PCLK_MUX_PCLK" to "JH7110_SYSCLK_PCLK2_MUX_FUNC" and
"JH7110_SYSCLK_PCLK2_MUX".
- Rewrote the DT bindings of clock and reset for using auxiliary bus.
- Registered an auxiliary device for reset controller in clock drivers.
- Changed clock names "CODAJ*" and "WAVE*" to "codaj*" and "wave*".
Changed clock names "u2_pclk_mux_func_pclk" and "u2_pclk_mux_pclk" to
"pclk2_mux_func" and "pclk2_mux".
- Changed the flags of clock apb0 and noc_bus_isp_axi to CLK_IS_CRITICAL
as suggested by StarFive SDK group.
- Registered clock gmac0_gtxc as a gate clock instead of a div clock
as suggested by StarFive SDK group.
- Changed the frequency of clock pll2_out to 1188MHz as suggested by
StarFive SDK group.
- Fixed the bug that the clock JH7110_AONCLK_GMAC0_GTXCLK was not handled
in JH7110 always-on clock driver.
- Registered the reset driver as an auxiliary driver.
- Reworded the commit messages.

From: Emil Renner Berthing <kernel@esmil.dk>
The clock control registers on the StarFive JH7100 and JH7110 work
identically, so factor out the code then drivers for the two SoCs
can share it without depending on each other. No functional change.

* [PATCH v2 01/14] clk: starfive: Factor out common JH7100 and JH7110 code

From: Emil Renner Berthing <kernel@esmil.dk>
The clock control registers on the StarFive JH7100 and JH7110 work
identically, so factor out the code then drivers for the two SoCs
can share it without depending on each other. No functional change.

The StarFive JH7100 SoC has additional reset controllers for audio and
video, but the registers follow the same structure. On the JH7110 the
reset registers don't get their own memory range, but instead follow the
clock control registers. The registers still follow the same structure
though, so let's factor out the common code to handle all these cases.

* [PATCH v2 04/14] reset: starfive: Factor out common JH71X0 reset code

From: Emil Renner Berthing <kernel@esmil.dk>
The StarFive JH7100 SoC has additional reset controllers for audio and
video, but the registers follow the same structure. On the JH7110 the
reset registers don't get their own memory range, but instead follow the
clock control registers. The registers still follow the same structure
though, so let's factor out the common code to handle all these cases.

* [PATCH v2 06/14] reset: starfive: jh71x0: Use 32bit I/O on 32bit registers

From: Emil Renner Berthing <kernel@esmil.dk>
We currently use 64bit I/O on the 32bit registers. This works because
there are an even number of assert and status registers, so they're only
ever accessed in pairs on 64bit boundaries.
There are however other reset controllers for audio and video on the
JH7100 SoC with only one status register that isn't 64bit aligned so
64bit I/O results in an unaligned access exception.
Switch to 32bit I/O in preparation for supporting these resets too.

* [PATCH v2 06/14] reset: starfive: jh71x0: Use 32bit I/O on 32bit registers

From: Emil Renner Berthing <kernel@esmil.dk>
We currently use 64bit I/O on the 32bit registers. This works because
there are an even number of assert and status registers, so they're only
ever accessed in pairs on 64bit boundaries.
There are however other reset controllers for audio and video on the
JH7100 SoC with only one status register that isn't 64bit aligned so
64bit I/O results in an unaligned access exception.
Switch to 32bit I/O in preparation for supporting these resets too.

nit: consider just passing the owner directly, so this would just be
data->rcdev.owner = owner;
..and callers that used false can just pass NULL.

Is it important to register this with the auxiliary device and not
just use the parent device?
If not you can just always pass the device that has the right of_node
and have this be
data->rcdev.of_node = dev->of_node;

It doesn't seem like syscrg, aoncrg or stgcrg have any inverted lines.
Do you know if any other CRGs do? If not you can just leave out the
.asserted member and always pass NULL.

This struct isn't used outside of reset-starfive-jh7110.c, so no need
to define it in this header.
Also consider calling it jh7110_reset_info so it blends in with the
functions defined in that file.

I don't see any reason you'd want to build a kernel that needs the
clock driver but not the resets, so I don't think this is something we
should optimize for. I'd just drop this patch and let such broken
kernels register the auxiliary devices even when no reset driver is
there to use them.

Your original patch merged patch 1 and patch 2. Suggested by Stephen, I
split the patch into two patches, and I need to add a new commit. My
previous thinking was that the Co-developed-by tag should not be added
to the commit author, so I added it to you.

Even if you didn't just copy it[1] I still don't think splitting
patches counts as "developed by". You can set the author of new
commits or copy them from a previous commit with git commit -c.

The description is bad, but even the documentation calls it "clk_rtc"
even though it's really an optional input from a 32k oscillator.

Okay, I will remove my Co-developed-by tag in patch 1, 2, 4, 5 and set the
commit author as you.

Oh, I don't even know you still work on JH7110 and update on github.. All
your patches were cherry-picked from your gitlab branch. There is no doubt
that we did the same thing for this patch.

Should I split this file into two files for "SYSCRG" and "AONCRG", which
maybe named as "starfive-jh7110-sys.h" and "starfive-jh7110-aon.h". Ditto

Maybe it can be used in JH7100 audio reset?

All JH7110 CRGs don't have inverted lines, and it could be modified as
what you said.

Maybe it can be used in JH7100 audio reset?

You're right. I made this patch just following the style of jh7100.
And I think it's better to select RESET_STARFIVE_JH7110 in config
CLK_STARFIVE_JH7110_SYS.

I synchronized these flags before with StarFive JH7110 SDK which is not
released yet. But you're right, the core clocks should be enabled and the
debug/trace clocks could be disabled during system booting. After some
discussion, we think it's more appropriate to remove the flags of
trace/debug clocks and set the flags of core clocks as CLK_IS_CRITICAL.

Because the aoncrg driver depends on the syscrg driver, which is set
in Kconfig.

I synchronized these flags before with StarFive JH7110 SDK which is not
released yet. But you're right, the core clocks should be enabled and the
debug/trace clocks could be disabled during system booting. After some
discussion, we think it's more appropriate to remove the flags of
trace/debug clocks and set the flags of core clocks as CLK_IS_CRITICAL.

Because the aoncrg driver depends on the syscrg driver, which is set
in Kconfig.

As we discussed in patch 7, could I merge patch 7, 8, 9, 10 and add the
following files in one commit?

You can keep aon and sys split. First add one of them with their own
headers. Then add second with their own defines.

You mean split patch 7 and patch 8 into sys part and aon part
respectively? There are totally five regions (sys/aon/stg/isp/vout)
for clocks and resets in JH7110. If we do that, there will be 5
headers for JH7110 in either clock or reset directory finally. Is
that OK if there are too many headers for just one SoC?
Best regards,
Hal

Sorry, I lost the track of what patches you have. The comment was -
bindings include both the doc and headers. You want to split some, some
merge, sorry, no clue. I did not propose splitting headers...

It's ok. The problem was that the header
include/dt-bindings/clock/starfive,jh7110-crg.h
was used in both
Documentation/devicetree/bindings/clock/starfive,jh7110-syscrg.yaml
and
Documentation/devicetree/bindings/clock/starfive,jh7110-aoncrg.yaml.
The same for include/dt-bindings/reset/starfive,jh7110-crg.h.
So should I add these four files in one patch?
Best regards,
Hal

It's ok. The problem was that the header
include/dt-bindings/clock/starfive,jh7110-crg.h
was used in both
Documentation/devicetree/bindings/clock/starfive,jh7110-syscrg.yaml
and
Documentation/devicetree/bindings/clock/starfive,jh7110-aoncrg.yaml.
The same for include/dt-bindings/reset/starfive,jh7110-crg.h.
So should I add these four files in one patch?

No. I think I wrote proposed flow of patches:
1. syscrg bindings with header
2. aoncrg bindings with changes to header
Why do you need to merge anything?
