Subject: [PATCH v1 22/22] riscv: dts: starfive: jhb100: Add clocks and resets nodes
Date: Thu,  2 Apr 2026 03:55:23 -0700	[thread overview]
Message-ID: <20260402105523.447523-23-changhuang.liang@starfivetech.com> (raw)
In-Reply-To: <20260402105523.447523-1-changhuang.liang@starfivetech.com>

Add clocks and resets nodes for JHB100 RISC-V BMC SoC. They contain
sys0crg/sys1crg/sys2crg/per0crg/per1crg/per2crg/per3crg.
