Subject: [PATCH] arm64: dts: rockchip: Fix vdd_log on rk3399-roc-pc
Date: Tue, 12 Nov 2019 12:42:09 +0100	[thread overview]
Message-ID: <d786ef47-eda8-3994-2ef2-fc4a584bcdcc@fivetechno.de> (raw)
In-Reply-To: <fd9ee2bc-9dfb-1aa2-f00f-add9b3069876@web.de>

On rk3399 vdd_log shall not exceed 1.0 V. On rk3399-roc-pc
vdd_log is presently 1118 mV. Fix by setting the min voltage
of the respective pwm-regulator down to 450 mV.
This results in a vdd_log of 953 mV.
Specify the supply to silence warning.
