Subject: [PATCH 1/3] arm64: dts: rockchip: Fix min voltage for rk3399-firefly vdd_log
Date: Mon, 11 Nov 2019 08:51:56 +0800 [thread overview]
Message-ID: <20191111005158.25070-1-kever.yang@rock-chips.com> (raw)
The min/max value of vdd_log is decide by pwm IO voltage and its
resistors, the rk3399-firefly board's pwm regulator circuit is designed
for IO voltage at 1.8V, while the board actually use 3.0V for IO, which
at last lead to the min-microvolt to '430mV' instead of '800mV'.
