    Subject[PATCH 1/3] ARM: dt: tegra: cardhu: add entry for PMIC TPS65911.
    Date
    Tegra30 based platform "cardhu" have the power management
    IC TPS65911 for the regulator.
    Adding DT entry for this device.
    Data are chosen from downstream kernel and making the
    voltage output as require by default for device to
    operate.
    The default interrupt line is HIGH from PMIC device and so
    inverting the interrupt detection line of PMU interrupt
    through configuring PMC.
    In this patch, do not registering LDO5 because the input
    supply for this rail is different for different version of
    cardhu i..e A02 and A04. The registration will be done once
    the dts file for cardhu A02 and A04 are added in follow on
    patches.
