Date: Sat, 25 May 2019 21:02:02 +0200 From: Martin Blumenstingl <martin.blumenstingl@...glemail.com> To: linux-amlogic@...ts.infradead.org, khilman@...libre.com Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Martin Blumenstingl <martin.blumenstingl@...glemail.com> Subject: [PATCH 2/4] ARM: dts: meson8b: ec100: add the VDDEE regulator 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.
