    clk: sunxi-ng: Implement factors offsets · e66f81bb
    Maxime Ripard authored
    The factors we've seen so far all had an offset of one. However, on the
    earlier Allwinner SoCs, some factors could have no offset at all, meaning
    that the value computed to reach the rate we want to use was the one we had
    to program in the registers.
    
    Implement an additional field for the factors that can have such an offset
    (linears, not based on a power of two) to specify that offset.
    
    This offset is not linked to the extremums that can be specified in those
    structures too. The minimum and maximum are representing the range of
    values we can use to try to compute the best rate. The offset comes later
    on when we want to set the best value in the registers.
