From 9dce0287a60d72656a787b075f1b9162ff3cb142 Mon Sep 17 00:00:00 2001 From: Alan Tull Date: Tue, 1 Nov 2016 14:14:23 -0500 Subject: fpga: add method to get fpga manager from device The intent is to provide a non-DT method of getting ahold of a FPGA manager to do some FPGA programming. This patch refactors of_fpga_mgr_get() to reuse most of it while adding a new method fpga_mgr_get() for getting a pointer to a fpga manager struct, given the device.
