Subject: [PATCH v3 2/3] rockchip: rk3568: make the TSADC trigger a first global reset
Date: Mon, 29 Jun 2026 20:20:11 +0200	[thread overview]
Message-ID: <20260629182012.1508336-3-andreas.zdziarstek@gmail.com> (raw)
In-Reply-To: <20260629182012.1508336-1-andreas.zdziarstek@gmail.com>

Same rationale as the watchdog: the default second global reset leaves
the SoC hung. Set the TSADC to the first global reset as well, so a
thermal shutdown reliably resets the whole SoC.
