My guess is that you did it that way to deal with the A33? If so, we can just request the cell size to be 1 for now, and then expand it to an enum later on when we'll support the A33. > + nvmem-cells: > + items: > + - description: ths calibrate data > + > + nvmem-cell-names: > + items: > + - const: calib Same remark than for the clocks > + > +required: > + - compatible > + - reg > + - interrupts > + - reset > + - clocks > + - clock-names I guess you'd need #thermal-sensor-cells too?
