[PATCH v3 00/22] Add basic clocks and resets for JHB100 SoC

[Changhuang Liang <changhuang.liang@starfivetech.com>]

The JHB100 SoC includes CRG (Clock and Reset Generator) for multiple
subsystems:

The JHB100 SoC is divided into multiple subsystems, and basically
each subsystem includes a CRG(Clock and Reset Generator):
 - sys0crg/sys1crg/sys2crg/
 - per0crg/per1crg/per2crg/per3crg/
 - voutcrg
 - vcecrg
 - gpu0crg/gpu1crg
 - cpucrg
 - usbcrg
 - host0crg/host1crg
 - pcierpcrg
 - husb0crg/husb1crg
 - husbcmncrg
 - husbd0crg/husbd1crg
 - npucrg

In the current series, we will only add the following CRG:
 - sys0crg/sys1crg/sys2crg/
 - per0crg/per1crg/per2crg/per3crg/

The remaining CRG will be implemented in future series.

This series depends on the series:
https://lore.kernel.org/all/20260806122553.182449-1-changhuang.liang@starfivetech.com/
and it has been tested on the StarFive JHB100 EVB-1.

changes since v2:

PATCH 5/7/9/11/13/15/17/19:
- Fix file name errors:
  <dt-bindings/reset/starfive-jhb100-crg.h> ==> <dt-bindings/reset/starfive,jhb100-crg.h>

PATCH 6:
- Execute kfree (rdev) on the path where auxiliary_device_init() returns an error;
- Check the return value of devm_pm_runtime_enable().
- Replace struct jhb100_crg_domain_info with struct starfive_crg_domain_info
  for common files.
- Restructure index validation in `starfive_clk_get`, add sparse
  hole check to return `-ENOENT` for unregistered clock entries.

PATCH 6/8/10/12/14/16/18/20:
- Repalce module_platform_driver() with builtin_platform_driver()
- Add missing static qualifier.

patch 21:
- Mark struct starfive_reset_info as const.
- Mark struct starfive_reset_map as const.
- Fix typo: discontigous ==> discontiguous
- Fix typo: JHB110 ==> JHB100
- For discontiguous type of reset controller, use ARRAY_SIZE()
  to calculate the number of resets.
- Add STARFIVE_RESET_ID_INVALID for handling invalid ID cases.

v1: https://lore.kernel.org/all/20260402105523.447523-1-changhuang.liang@starfivetech.com/
