Subject: [PATCH v11 15/27] pwm: jz4740: Allow selection of PWM channels 0 and 1
Date: Thu, 28 Mar 2019 00:16:19 +0100 [thread overview]
Message-ID: <20190327231631.15708-16-paul@crapouillou.net> (raw)
In-Reply-To: <20190327231631.15708-1-paul@crapouillou.net>
The TCU channels 0 and 1 were previously reserved for system tasks, and
thus unavailable for PWM.
