    Subject[PATCH v8 0/9] Multicolor FW v8 update
    Date
    Hello

    Per request I removed the ops structure. But there is a potential need for some
    device drivers to have a call back that sets the intesity of the LED color
    without modifying the hardware register. The hardware registers are only updated
    when the brightness_set<op> is called. The need arises with the LP50xx chip
    series where the chip has 2 control knobs to modify the output current to the
    LED. In most cases drivers only have a single brightness register for a given
    iOUT pin. But the LP50xx has a brightness register that controls cluster
    brightness and individual registers to control the monochrome LED intensity.

    The set_color_brightness call back has been simplified in the LP50xx device
    driver so that it can cache the LED intensity in it's stack for a specific color
    as opposed to having to call back into the MC FW for the current intensity which
    made the driver complex.
    Once the set_brightness<op> is called the driver can set the brightness and then
    set the LED intensity registers if the driver has that ability.
