[PATCH v2 1/3] ARM: dts: rockchip: raise CPU trip point temperature for veyron to 100 degC

[Matthias Kaehlcke]

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.

[PATCH v2 2/3] ARM: dts: rockchip: raise GPU trip point temperatures for veyron

[Matthias Kaehlcke]

The values match thorse used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for veyron devices. Keep the critical
trip point for speedy at 90°C as in the downstream configuration.

[PATCH v2 3/3] ARM: dts: raise GPU trip point temperature for speedy to 80 degC

[Matthias Kaehlcke]

Raise the temperature of the GPU thermal trip point for speedy
to 80°C. This is the value used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for speedy.

applied all 3 for 5.3 with Doug's RB and did a small fix to the commit
message of patch2 ("thorse").
