Subject: [PATCH] arm: dts: fix rk3066a based boards vdd_log voltage initialization
Date: Mon, 19 Sep 2016 16:44:56 +0800 [thread overview]
Message-ID: <1474274696-28090-1-git-send-email-andy.yan@rock-chips.com> (raw)
In-Reply-To: <1474274639-27768-1-git-send-email-andy.yan@rock-chips.com>
The current rk3066a based boards(Rayeager, Bqcurie2, Marsboard) use
pwm modulate vdd_logic voltage, but the pwm is default disabled and
the pwm pin acts as a gpio before pwm regulator probed, so the pwm
regulator driver will get a zero dutycycle at probe time, so change
the initial dutycycle to zero to match pwm_regulator_init_state check.
