[PATCH v6 0/2] clk: add support for TI CDCE6214

[Sascha Hauer]

The CDCE6214 is a Ultra-Low Power Clock Generator With One PLL, Four
Differential Outputs, Two Inputs, and Internal EEPROM.

This series adds a common clk framework driver for this chip along with
the dt-bindings document.

The most controversial part of this series was the binding I introduced
for configuring the pins of the CDCE6214. With v6 I have now integrated
a pinctrl driver into the driver in the hope that this silences the
discussion around the pins.

Changes in v6:
- use pinctrl subsystem to configure pins
- Link to v5: https://lore.kernel.org/r/20250618-clk-cdce6214-v5-0-9938b8ed0b94@pengutronix.de

Changes in v5:
- Reword commit message for binding patch (Krzysztof)
- Make clock binding yaml simpler (Krzysztof)
- add link to datasheet to driver code (Stephen)
- Drop inclusion of linux/clk.h (Stephen)
- Add missing #include <linux/bitfield.h> (Kernel test robot)
- simplify cdce6214_clk_out0_get_parent() (Stephen)
- Use divider_get_val() where appropriate (Stephen)
- Add Rxx defines for registers (Stephen)
- Add define for magic value 24 (Stephen)
- introduce and use cdce6214_clk_psx_mask() (Stephen)
- Use clamp() instead of open code (Stephen)
- declare const arrays const (Stephen)
- more use of dev_err_probe() (Stephen)
- use determine_rate() instead of round_rate (Stephen)
- split out pin configuration to separate patches
- Link to v4: https://lore.kernel.org/r/20250430-clk-cdce6214-v4-0-9f15e7126ac6@pengutronix.de

Changes in v4:
- add missing '>' modifier in include/dt-bindings/clock/ti,cdce6214.h
- fix clocks maxItems should be 2
- add missing license in include/dt-bindings/clock/ti,cdce6214.h
- Fix checkpatch issues
- Link to v3: https://lore.kernel.org/r/20250410-clk-cdce6214-v3-0-d73cf9ff3d80@pengutronix.de

Changes in v3:
- Use string properties instead of int for enums
- Use units from property-units in dtschema
- Link to v2: https://lore.kernel.org/r/20250409-clk-cdce6214-v2-0-40b25b722ecb@pengutronix.de

Changes in v2:
- Use consistent quotes in binding document
- make clock-names an enum to make each clock fully optional
- drop '|' in binding description where not needed
- encode clock input mode into integer
- encode clock output mode into integer
- do not use defines for reg properties
- support setting load capacity for the oscillator via device tree
- support setting Bias current for the oscillator via device tree
- support setting polarities of CMOS outputs via device tree
- fix compatible string in driver
- remove unused struct cdce6214_config
- Link to v1: https://lore.kernel.org/r/20250408-clk-cdce6214-v1-0-bd4e7092a91f@pengutronix.de

[PATCH v6 2/2] clk: add TI CDCE6214 clock driver

[Sascha Hauer]

The CDCE6214 is a Ultra-Low Power Clock Generator With One PLL, Four
Differential Outputs, Two Inputs, and Internal EEPROM. This patch adds
a common clk framework driver for this chip.

- Two inputs (PRIREF and SECREF)
- Programmable 8bit divider or x2 multiplier between input and PLL
- 16b integer / 24bit fractional PLL
- Two programmable /4, /5, /6 dividers after PLL (PSA/PSB)
- Four outputs (OUT1-OUT4) with programmable 14b dividers,
  muxable between PSA, PSB and PLL input
- One output (OUT0) fed from PLL input

- PRIREF can be configured as LVCMOS or differential input
- SECREF can be configured as LVCMOS, differential or oscillator input
- OUT0 is a LVCMOS output
- OUT1 and OUT4 can be configured as LVDS, LP-HCSL or LVCMOS outputs
- OUT2 and OUT3 can be configured as LVDS or LP-HCSL outputs

All clocks are registered without parent rate propagation, so each of
the clocks must be configured separately via device tree or consumer.

I don't understand what is happening here.

Patch changed in weird and unexplained way - nothing in the changelog
explains dropping SPDX - and does not pass even checkpatch.

I removed the SPDX by accident, will add it back of course.

Other than that, what's weird? Changelog says I now use the pinctrl
subsystem to configure pins. OK, that also changes the binding, I could
have mentioned that explicitly, sorry for that.

There were four patches before, now there are two and changelog says
only about pinctrl to configure pins. That's very vague and you expect
me to decipher what changed in the bindings.

In v5 I tried splitting the driver/bindings up into a basic part which
and a part which added the pin config stuff in the hope that the first
two patches could be applied first. This was not very well received, so
I merged it back.

I am aware that the binding looks quite different now, but this really
goes down to using the pinctrl bindings now.
