[PATCH v5 00/10] clk: realtek: Add RTD1625 clock support

[Yu-Chun Lin]

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 v5:
patch 1:
- Removed hardware bit position encoding from the reset binding and redesgined
reset IDs as sequential values.

patch 2:
- Reordered device nodes alphabetically.

patch 3:
- Created drivers/reset/realtek/ directory and include/linux/reset/realtek.h.
- Extracted the common reset helpers:
 - Moved the source code to drivers/reset/realtek/common.c and
 - the header to include/linux/reset/realtek.h
- Renamed rtk_reset_bank to rtk_reset_desc.
- Added 'bits' member to rtk_reset_desc structure.
- Removed rtk_reset_get_id() and rtk_reset_get_bank() helper.
- Introduced rtk_reset_get_desc().

patch 4:
- Synchronized with reset controller changes.

patches 9-10:
- Added #include <dt-bindings/reset/realtek,rtd1625.h> in drivers.
- Replaced rtk_reset_bank arrays with rtk_reset_desc descriptors.
- Implemented complete mapping tables for all reset IDs.
