Subject: [PATCH v2 3/5] arm64: dts: mt7986: change cooling trips
Date: Wed, 25 Oct 2023 19:08:30 +0200 [thread overview]
Message-ID: <20231025170832.78727-4-linux@fw-web.de> (raw)
In-Reply-To: <20231025170832.78727-1-linux@fw-web.de>
From: Frank Wunderlich <frank-w@public-files.de>
Add Critical and hot trips for emergency system shutdown and limiting
system load.
Change passive trip to active to make sure fan is activated on the
lowest trip.
Fixes: 1f5be05132f3 ("arm64: dts: mt7986: add thermal-zones")
Fixes: c26f779a2295 ("arm64: dts: mt7986: add pwm-fan and cooling-maps to BPI-R3 dts")
Suggested-by: Daniel Golle <daniel@makrotopia.org>
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>

v2:
- squash patch for bpi-r3 as suggested by angelo
