Subject: [PATCH v4 0/3] clk: add support for TI CDCE6214

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 and a small fix needed for the common clk
framework.

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

- 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
