[PATCH v4 0/8] clk: amlogic: Add A5 SoC PLLs and Peripheral clock

[Chuan Liu via B4 Relay]

The patchset adds support for the peripheral and PLL clock controller
on the Amlogic A5 SoC family, such as A113X2.

Due to work arrangements, I will take over this patchset and be
responsible for submitting and maintaining its subsequent revisions.

I previously resubmitted these patches in another patchset [1],
Jerome pointed out that it made tracking more difficult. Therefore,
I’m continuing the submission here based on Xianwei’s v3 version.
Sorry for this causes any inconvenience to anyone.

Changes in v4:
- dt-binding for peripheral clocks (kept Rob’s 'Reviewed-by' here):
  - Added optional clock source rtc pll.
  - Renamed rtc_clk’s clkid to better reflect its function.
- PLL/Clock driver:
  - Adapted to Jerome’s refactored driver interface, naming
conventions, and macros.
  - Updated related CONFIG entries in Kconfig.
- Added dts patch of PLL/Clock.
- Link to v3: https://lore.kernel.org/r/20250103-a5-clk-v3-0-a207ce83b9e9@amlogic.com

Changes in v3:
- Rename xtal_24m to xtal, and modify some description of Kconfig.
- Drop some comment of PLL source code.
- Move definition of A5_CLK_GATE_FW frome common code into A5 peripheral source code.
- Use hw instead of name to describe parent_data.
- Making SCMI binding the first to submit.
- Link to v2: https://lore.kernel.org/r/20241120-a5-clk-v2-0-1208621e961d@amlogic.com

Changes in v2:
- Move some sys clock and axi clock from peripheral to scmi impletement.
- Remove  ARM_SCMI_PROTOCOL in Kconfig and correct name A5 but not A4.
- Add two optional clock inputs for the peripheral(ddr pll and clk-measure)
- Make some changes and adjustments according to suggestions.
- Link to v1: https://lore.kernel.org/r/20240914-a5-clk-v1-0-5ee2c4f1b08c@amlogic.com
