Subject: [PATCH 2/2 v2] arm64: dts: ls208xa: add more thermal zone support
From: Yuantian Tang <andy.tang@....com>
There are 7 thermal zones in ls208xa soc. Add the other thermal zone
nodes to enable them.
Signed-off-by: Yuantian Tang <andy.tang@....com>
---
v2:
- remove useless alert trip
- add cooling-map to core cluster zones.
