Hello,

This patch series adds clock support for Realtek's RTD1625 platform.
The series includes:
1. Device Tree: Add clock controller nodes.
2. Infrastructure: reset controller, basic clocks, PLLs, gate clocks, mux
clocks, and MMC-tuned PLLs.
3. Platform drivers: two clock controller drivers for RTD1625-CRT and
RTD1625-ISO.

Best regards,
Yu-Chun Lin

Changes in v8:

Patch 3:
- Add depends on RESET_CONTROLLER and select MFD_SYSCON for config
RTK_CLK_COMMON
- Fix error handling for devm_auxiliary_device_create()

Patch 4:
- Reduce the timeout value in regmap_read_poll_timeout_atomic() from 2000ms to
500ms to avoid prolonged busy-waiting and prevent triggering the NMI Watchdog
- Remove 'freq_ready_valid' and add comments to clarify that register offset 0
is never a valid address on Realtek SoCs, meaning it is not configured
- Add the missing spin_unlock_irqrestore() when regmap_read() fails

Patch 6:
- In clk_regmap_mux_get_parent(), return 0xff instead of 0 to properly indicate
an error
- In clk_regmap_mux_set_parent(), cast index to u32 to avoid signed integer
- overflow

Patch 7:
- Fix the mask shift in set_phrt0()
- For better safety and readability, modify pointer comparison for phase_id
- In clk_pll_mmc_recalc_rate(), return 0 instead of an error code upon failure

Patch 8 & 9:
- Remove the trailing NULL element ([RTD1625_XX_CLK_MAX] = NULL) from the
clk_hw_onecell_data arrays
- Add MODULE_DEVICE_TABLE(of, ...) for the tristate config
- Add  '.suppress_bind_attrs = true', to avoid handling pointer problem, cause
clock should not allow to manually disable by users
- Fix a typo

Patch 10:
- Sort device nodes by unit address
