    clk: qcom: reset: support resetting multiple bits · 4a521089

    This patch adds the support for giving the complete bitmask
    in reset structure and reset operation will use this bitmask
    for all reset operations.
    
    Currently, reset structure only takes a single bit for each reset
    and then calculates the bitmask by using the BIT() macro.
    
    However, this is not sufficient anymore for newer SoC-s like IPQ8074,
    IPQ6018 and more, since their networking resets require multiple bits
    to be asserted in order to properly reset the HW block completely.
    
    So, in order to allow asserting multiple bits add "bitmask" field to
    qcom_reset_map, and then use that bitmask value if its populated in the
    driver, if its not populated, then we just default to existing behaviour
    and calculate the bitmask on the fly.
