Subject: [PATCH 0/1] ARM: dts: meson8b: another GPU fix
Date: Sun, 12 May 2019 21:39:35 +0200 [thread overview]
Message-ID: <20190512193936.26557-1-martin.blumenstingl@googlemail.com> (raw)
Currently I am working on the PWM driver to complete .get_state()
support. This allowed me to read the VDDEE voltage set by u-boot
on my Meson8b boards (EC-100 and Odroid-C1). VDDEE supplies the
Mali GPU.
It turns out that the bootloader configures a VDDEE voltage of 1.10V
instead of 1.15V. 1.15V is actually out-of-range for that regulator
design.
This is meant to be applied on top of my other GPU fixes from [0]
also targetting v5.2 if possible.
