Subject: [PATCH v3 0/2] hwrng: starfive: updates for jh7110-trng DT binding and driver fixes
Date: Mon,  1 Jun 2026 17:37:42 +0800	[thread overview]
Message-ID: <20260601093744.84210-1-lianfeng.ouyang@starfivetech.com> (raw)

From: Lianfeng Ouyang <lianfeng.ouyang@starfivetech.com>

- the obsolete JH8100 compatible string is dropped, support for the new
  JHB100 SoC is added, and the schema is simplified to an enum.
- The driver is updated to handle the JHB100's specific hardware
  requirement where clocks must be disabled beforeasserting reset during
  teardown, to avoid glitches. This is implemented via a per-compatible
  data flag (SEQ_CLK_FIRSTfor JHB100, preserving SEQ_RST_FIRSTfor JH7110).
- Several Runtime Power Management (RPM) fixes are included to ensure
  proper autosuspend behavior, balanced runtime usage counting, and
  correct cleanup ordering on probe failure or device removal.
