Hi, I was wondering if there is a way to completely "shutdown" (power off) the GPU or put it into "low power" (suspend) mode? Just setting the gpu state to disabled is probably the wrong as it won't give the SYR828 PMIC anymore and u-boot likely enables it all. If it's possible would anyone have a dtso to do that? /bz -- Bjoern A. Zeeb r15:7
