Subject: [patch 8/8] RFC: drivers/pwm/rk_pwm.c: Fix default polarity
Date: Fri, 25 Sep 2020 20:37:02 +0200 [thread overview]
Message-ID: <20200925183856.699546249@rtp-net.org> (raw)
In-Reply-To: 20200925183654.723338620@rtp-net.org
In the code, the default polarity is set to positive/positive,
which is neither normal polarity or inverted polarity. It's
only the hardware default. This leads to booting linux with
wrong polarity setting.
Update the code to use PWM_DUTY_POSTIVE | PWM_INACTIVE_NEGATIVE
by default instead.
