* ZTE zx2967 family Thermal Required Properties: - compatible: should be one of the following. * zte,zx296718-thermal - reg: physical base address of the controller and length of memory mapped region. - clocks : Pairs of phandle and specifier referencing the controller's clocks. - clock-names: "topcrm" for the topcrm clock. "apb" for the apb clock. - #thermal-sensor-cells: must be 0. Please note: slope coefficient defined in thermal-zones section need to be multiplied by 1000.
