I tried to google and search through this forum, but I haven't found anything close to this.
Environment:
I am running a LS1043a CPU with OpenWrt from qoriq-components repository.
In section 35 of the LS1043A Reference Manual, it says there are 5 local temperature sensors?
Are these registers available to be read (do they need to be calibrated)?
I guess what I'm saying is that I don't really know how to use the TMU and what I need to configure in the device tree to be able to use it. There seems no guide.
The default LS1043a device tree has "thermal_zones". Are these the sensors (although they have eight(8) thermal zones (0-8) in the device tree).
I am happy to read manuals if there was one.
Thanks in advance!
The processor temperature sensors can be read via SYSFS. LSDK online documentation has a article explaining how to enable and use it. The recommendations are very basic and should work in any distro.
Hope it helps,
