[PATCH v4 0/2] clk: amlogic: Add A9 peripherals clock controller

[Jian Hu via B4 Relay <devnull+jian.hu.amlogic.com@kernel.org>]

This series adds Amlogic A9 peripherals clock support,
including dt-binding and peripherals clock driver.

Note that this driver depends on the A9 PLL driver, which is not yet
upstream. The Meson PLL framework is currently undergoing refactoring,
and the A9 PLL driver will be submitted as a follow-up series after
that work has been completed.

Changes in v4:
- Expose channel 3 for gen_clk.
- Add suffix 0 for some clocks.
- Use helper macro for vclk clocks definitions.
- Drop forward declaration.
- Drop CLK_HW_INIT* and revert to explicit clock declarations.
- Fix can clock channel number comment.
- Rename enc clocks to encoder0/encoder1.
- Link to v3: https://lore.kernel.org/r/20260610-a9_peripherals-v3-0-d07a78085f71@amlogic.com

Changes in v3:
- Add "depend on A9 pll" instructions in the cover-letter.
- Move COMPILE_TEST after 'depends on ARM64' reported by sashiko-bot.
- Fix usb_48m_pre_sel's parent reported by sashiko-bot.
- Fix gen_div width reported by sashiko-bot.
- Fix hdmitx1_pixel's parent reported by sashiko-bot.
- Link to v2: https://lore.kernel.org/r/20260603-a9_peripherals-v2-0-ee1b8c0a1e6c@amlogic.com

Changes in v2:
- Split the A9 clock driver and send the peripherals clock separately.
- Add COMPILE_TEST in Kconfig.
- Drop the 'optional'.
- Rename apb4 to soc.
- Sort the header file.
- Rename hifi to hifi0.
- Use CLK_HW_INIT_PARENTS_DATA to describe clk_init_data.
- Use CLK_HW_INIT_HW to describe clk_init_data.
- Use CLK_HW_INIT_PARENTS_HW to describe clk_init_data.
- Link to v1: https://lore.kernel.org/all/20260511-b4-a9_clk-v1-0-41cb4071b7c9@amlogic.com/
