Subject: [RFC 1/3] dts64: mt7622: enable all pwm for bananapi r64
Date: Fri, 16 Oct 2020 22:40:17 +0200	[thread overview]
Message-ID: <20201016204019.2606-2-linux@fw-web.de> (raw)
In-Reply-To: <20201016204019.2606-1-linux@fw-web.de>

From: Frank Wunderlich <frank-w@public-files.de>

mt7622 only supports 6 pwm-channels so drop pwm7

third pwm (pwm2) is inverted and connected to fan-socket
