Subject: [PATCH] ARM: dts: BCM5301X: Add CPU thermal sensor and zone
|
|
MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8

This uses CPU thermal sensor available on every Northstar chipset to
|
|
monitor temperature. We don't have any cooling or throttling so only a
|
|
critical trip was added.
