Subject: [PATCH v2 4/4] ARM: dts: meson8b: mxq: add the VDDEE regulator
Date: Sat, 27 Jul 2019 14:12:57 +0200
Message-ID: <20190727121257.18017-5-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190727121257.18017-1-martin.blumenstingl@googlemail.com>

The VDDEE regulator is basically a copy of the VCCK regulator. VDDEE
supplies for example the Mali GPU and is controlled by PWM_D instead of
PWM_C.

Add the VDDEE PWM regulator and make it the supply of the Mali GPU.
