[PATCH v1 13/13] riscv: dts: starfive: jhb100: Add syscon nodes

Changhuang Liang
2026-04-03T05:50:21Z

Add syscon nodes for JHB100 RISC-V BMC SoC. They contain
pcieep0_ecsr_syscon | host0_syscon | husb0_syscon | husbd0_syscon |
pcieep1_ecsr_syscon | host1_syscon | husb1_syscon | husbd1_syscon |
gpu0_syscon | gpu1_syscon | husbcmn_syscon | b2h0_syscon | b2h1_syscon |
h02b_syscon | h12b_syscon | vout_syscon | pcierp_ecsr_syscon |
pcierp_syscon | usb_syscon | npu_syscon | per0_syscon | per1_syscon |
per2_syscon | per3_syscon | sys0_syscon | sys1_syscon | sys2_syscon |
strap_syscon.

Simultaneously add the pll, reset, and chipid nodes under syscon.
Also update the references of pll nodes.
