How to disable Tinker GPU
#1
Hi,

I need to minimize power consumption at my Tinker Board.

One idea is to disable the GPU, but I do not know how, any help? Either at software (Debian) level or hardware level.

I noticed there is a dedicated regulator at the RK3808, the DCDC_REG2, which is set to "regulator-always-on;" and "regulator-boot-on;" at the corresponding .dtb file (the device tree readed when system boots up, file located at /boot/rk3288-miniarm.dtb)
Any one knows if I could directly disable that DC regulator, and how?

Thanks
