Tue May 12 01:35:21 PDT 2026
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 | b2h_syscon | h2b_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.
Also update the references of pll nodes.
