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 v4:
- Remove patches 1/2/3/4 in v4, and patches 1/2/3 are newly introduced in v5.
- Refactor the shared clock and reset implementation into JH71x0-specific helpers, updating
the affected drivers (These include patches 4/6/8/10/12/14/16/18/20/21/22 in v5.) to use
the new interfaces.
- Split patch 6 in v4 into patch 4 and patch 6 in the current v5.
- Split patch 21 in v4 into patch 21 and patch 22 in the current v5.
PATCH 17: (in v5)
- Add Krzysztof's Reviewed-by tag
