   4 Subject: mfd: ti_am335x_tscadc: Use PLATFORM_DEVID_AUTO while registering mfd
   5  cells

   7 [ Upstream commit b40ee006fe6a8a25093434e5d394128c356a48f3 ]
   8
   9 Use PLATFORM_DEVID_AUTO to number mfd cells while registering, so that
  10 different instances are uniquely identified. This is required in order
  11 to support registering of multiple instances of same ti_am335x_tscadc IP.
