Subject: [PATCH v3 4/4] arm64: dts: mt7986: add pwm-fan and cooling-maps to BPI-R3 dts
Date: Tue, 30 May 2023 22:12:35 +0200	[thread overview]
Message-ID: <20230530201235.22330-5-linux@fw-web.de> (raw)
In-Reply-To: <20230530201235.22330-1-linux@fw-web.de>

From: Daniel Golle <daniel@makrotopia.org>

Add pwm-fan and cooling-maps to BananaPi-R3 devicetree.

this is based on Patch from openwrt. as my PWM-fan seems to need 5v pwm
signal and r3 only provides 3v3 on 3pin-socket it does not work for me.
