    clk: sunxi: Give sunxi_factors_register a registers parameter · 7c74c220
    Hans de Goede authored
    Before this commit sunxi_factors_register uses of_iomap(node, 0) to get
    the clk registers. The sun6i prcm has factor clocks, for which we want to
    use sunxi_factors_register, but of_iomap(node, 0) does not work for the prcm
    factor clocks, because the prcm uses the mfd framework, so the registers
    are not part of the dt-node, instead they are added to the platform_device,
    as platform_device resources.
    
    This commit makes getting the registers the callers duty, so that
    sunxi_factors_register can be used with mfd instantiated platform device too.
    
    While at it also add error checking to the of_iomap calls.
    
    This commit also drops the __init function from sunxi_factors_register since
    platform driver probe functions are not __init.
