Hi All,
> Subject: [PATCH 0/2] Add GPU cooling device support
>
> Add GPU cooling device support for RZ/{G2L,G2LC,V2L} SMARC EVK.
I would like to drop this patch series as there is no thermal
Sensor unit available in mali gpu and there is no point in
Throttling GPU on high temp for the cases like GPU is on light load, but other loads on the system is very high.
Cheers,
Biju
