Subject: ARM: dts: am335x-evmsk: Add vtt_fixed regulator
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=12f0323685f4f1357169432d1ca8a75282f2233f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ARM: dts: am335x-evmsk: Add vtt_fixed regulator

The VTT regulator for DDR3 termination on the am335x-evmsk is
controlled by a gpio. It is configured by the bootloader so here we
define an always-on, fixed voltage regulator to hold the gpio.
