Hello,

This patch series adds clock support for Realtek's RTD1625 platform

The series includes:

1. Infrastructure: reset controller, basic clocks, PLLs, gate clocks, mux
clocks, and MMC-tuned PLLs.

2. Platform drivers: two clock controller drivers for RTD1625-CRT and
RTD1625-ISO.

I welcome feedback and suggestions.

Best regards,
Yu-Chun Lin

Changes in v3:
General:
- Added prefix "rtk_" in operation names to avoid duplicate symbol problem.
- Converted macro to static inline function.
patch 1:
- Converted header file path to the full path.
patch 2:
- Reduced the number of IDs per bank from 256 to 32, eliminating unnecessary
gaps.
- Used UL() to prevent undefined behavior.
patch 3 & 4:
- Optimized code structure by removing redundant elements.
- Replaced Read-Modify-Write operations in clk_pll_set_rate with
  regmap_update_bits()
