[PATCH v1 - resent 4/5] i2c: busses: Allow configurable adapter id for mlxcpld

From: michaelsh
Date: Tue Mar 27 2018 - 08:05:50 EST


From: Michael Shych <michaelsh@xxxxxxxxxxxx>

It allows mlxcpld driver to be connected to pre-defined adapter number
equal or greater than one, in order to avoid current limitation, assuming
usage of id number one only.
