The clock tree of Spacemit K1 is managed by several independent
controllers in different SoC parts. In this series, all clock hardwares
in APBS, MPMU, APBC and APMU, are implemented. With some changes to UART
driver, CPU cores and UARTs could be brought up (see below). More clocks
will be implemented later soon.
No device tree changes are included since Spacemit K1 UART needs two
clocks to operate, but for now the driver gets only one. I would like to
defer the changes until this is resolved.
Tested on BananaPi-F3 board, a clock tree dump could be obtained here[1].
This series depends on

Changed from v1
- add SoC prefix (k1)
- relicense dt-binding header
- misc fixes and style improvements for dt-binding
- document spacemit,k1-syscon
- implement all APBS, MPMU, APBC and APMU clocks
- code cleanup
- Link to v1: https://lore.kernel.org/all/SEYPR01MB4221B3178F5233EAB5149E41D7902@SEYPR01MB4221.apcprd01.prod.exchangelabs.com/

Add definition for the clock controllers of Spacemit K1 SoC. The clock
tree is managed by several SoC parts, thus different compatible strings
are added for each.
spacemit,k1-syscon.yaml is updated as well to allow clock controller
being its subnode.

The clock tree of K1 SoC contains three main types of clock hardware
(PLL/DDN/MIX) and is managed by several independent controllers in
different SoC parts (APBC, APBS and etc.), thus different compatible
strings are added to distinguish them.
Some controllers may share IO region with reset controller and other low
speed peripherals like watchdog, so all register operations are done
through regmap to avoid competition.

My bot found errors running 'make dt_binding_check' on your patch:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/soc/spacemit/spacemit,k1-syscon.example.dtb: /example-0/system-controller@d4050000: failed to match any schema with compatible: ['spacemit,mpmu-syscon', 'syscon', 'simple-mfd']
doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/SEYPR01MB42212A60B191731DF9759B7DD7602@SEYPR01MB4221.apcprd01.prod.exchangelabs.com
The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Please order patches correctly. First this, then the parent so you will
not submit incomplete binding.
You still must test it, though :(

We should simply clamp the rate here. It doesn't matter what 'rate' is
when this function is called. The callback is supposed to determine what
the clk rate will be if a consumer called clk_set_rate() with 'rate'.
Don't fail that if the rate is requested to be larger than max, just
tell clk_round_rate() that if you ask for something larger you'll get
PLL_MAX_FREQ.

Should I drop the example block in this binding completely and move it
to its parent's binding (the syscon) or just drop the parent here?

Please drop entire example from this binding and implement one, full
example in the parent binding file (so in the syscon).

Hi Stephen,
Sorry for such a late reply. FYI, I have sent a v3 and applied most of
your recommendation.

Thanks for the hint, all parents are described with struct
clk_parent_data in v3.

Thanks for the hint. This extra lock is dropped in v3. Since all
register operations to shared MMIO regions are performed through
regmap_update_bits(), there cannot be a race.

Okay, duplicated round_rate is deleted in v3.

Thanks, I drop the regmap wrappers for each clock type, but keep
ccu_{read,update} in v3 since they save a lot of keystrokes and make
the code easier to read.
