From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaud Patard (Rtp) Date: Tue, 27 Oct 2020 14:21:38 +0100 Subject: [patch v2 07/10] drivers/pwm/rk_pwm.c: Fix default polarity References: <20201027132131.016984025@rtp-net.org> Message-ID: <20201027132236.036333749@rtp-net.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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.
