    Subject[PATCH v4 07/21] hwmon: (mr75203) enable polling for all VM channels
    Date
    Configure ip-polling register to enable polling for all voltage monitor
    channels.
    This enables reading the voltage values for all inputs other than just
    input 0.

    V3 -> V2:
    - Move configuration of ip-polling register from previous patch to a
    separate commit.

    V4 -> V3:
    - Replace GENMASK(pvt->c_num - 1, 0) with (BIT(pvt->c_num) - 1).
