Subject: [PATCH 1/6] arm64: dts: rockchip: Fix rk3399-roc-pc pwm2 pin
Date: Thu, 19 Sep 2019 10:58:17 +0530 [thread overview]
Message-ID: <20190919052822.10403-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190919052822.10403-1-jagan@amarulasolutions.com>
ROC-PC is not able to boot linux console if PWM2_d is
unattached to any pinctrl logic.
To be precise the linux boot hang with last logs as,
...
.....
[ 0.003367] Console: colour dummy device 80x25
[ 0.003788] printk: console [tty0] enabled
[ 0.004178] printk: bootconsole [uart8250] disabled
In ROC-PC the PWM2_d pin is connected to LOG_DVS_PWM of
VDD_LOG. So, for normal working operations this needs to
active and pull-down.
This patch fix, by attaching pinctrl active and pull-down
the pwm2.
