Peter,
I'm trying to use this series to get thermal on rk3566 based tvbox (x96-x6).
Driver loads but i'm getting following error:
[ 132.873979] rockchip-thermal fe710000.tsadc: failed to register sensor 0: -517
[ 132.874650] rockchip-thermal fe710000.tsadc: failed to register sensor[0] : error = -517
Maybe you have some hints here?
