    Subject[PATCH AUTOSEL 4.20 002/105] mfd: ti_am335x_tscadc: Use PLATFORM_DEVID_AUTO while registering mfd cells
    Date
    From: Vignesh R <vigneshr@ti.com>

    [ Upstream commit b40ee006fe6a8a25093434e5d394128c356a48f3 ]

    Use PLATFORM_DEVID_AUTO to number mfd cells while registering, so that
    different instances are uniquely identified. This is required in order
    to support registering of multiple instances of same ti_am335x_tscadc IP.
