Subject: [PATCH 0/5]misc: Add afi config drivers support.

Xilinx SoC platforms (Zynq and ZynqMP) connect the PS to the
programmable logic (PL) through the AXI port.This AXI port helps
to establish the data path between the PS and PL. In-order to
establish to proper communication data path between PS and PL
the AXI port data path should be configured with the proper
Bus-width values

This patch series Adds afi config drivers support to handle the
PS-PL AXI port bus-width configurations.
