Subject: [PATCH v1 3/3] riscv: dts: starfive: jh7110: bootph-pre-ram hinting needed by boot loader
Date: Fri,  6 Jun 2025 06:02:38 -0700	[thread overview]
Message-ID: <20250606130253.1105273-4-e@freeshell.de> (raw)
In-Reply-To: <20250606130253.1105273-1-e@freeshell.de>

Add bootph-pre-ram hinting to jh7110.dtsi:
  - CPU interrupt controller(s)
  - core local interrupt timer
  - DDR memory controller
  - oscillator
  - syscrg clock-controller
