Subject: [PATCH v6 00/15] Add basic clocks and resets for JHB100 SoC
Date: Thu,  8 Oct 2026 05:33:23 -0700	[thread overview]
Message-ID: <20261008123338.11081-1-changhuang.liang@starfivetech.com> (raw)

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.

changes since v5:
- Remove the bindings related patch.

patch 4 (in v6):
- jh71x0_crg_probe(): report invalid parent indices with
  dev_err_probe() instead of returning a bare -EINVAL, so the failing
  clock name and index are visible in the log.
- Add #include <linux/property.h>.

patch 8 (in v6):
- Change the JH71X0_CLK_FRAC_MAX condition check to an else if.

patch 5/6/7/10/11/12/13 (in v6):
- Document the CLK_IS_CRITICAL and CLK_IGNORE_UNUSED policies.
