Subject: [PATCH 32/54] ARM: dts: rockchip: raise CPU trip point temperature
|
||
|
|
for veyron to 100 degC

This value matches what is used by the downstream Chrome OS 3.14
|
||
|
|
kernel, the 'official' kernel for veyron devices. Keep the temperature
|
||
|
|
for 'speedy' at 90°C, as in the downstream kernel.
|
||
|
|
|
||
|
|
Increase the temperature for a hardware shutdown to 125°C, which
|
||
|
|
matches the downstream configuration and gives the system a chance
|
||
|
|
to shut down orderly at the criticial trip point.
