Subject: [PATCH 05/28] ARM: dts: rockchip: fix the regulator's voltage range
|
|
on MiQi board
|
|
|
|
The board declared too narrow a voltage range for the CPU and GPU
|
|
regulators, preventing it from using the full CPU frequency range.
|
|
The regulators support 712500 to 1500000 microvolts.
|
|

(cherry picked from commit 95330e63a9295a2632cee8cce5db80677f01857a)
