From 845089bbf589be75143d0c9fb326d5595c1b5787 Mon Sep 17 00:00:00 2001 From: Alan Tull Date: Wed, 15 Nov 2017 14:20:28 -0600 Subject: fpga: add attribute groups Make it easy to add attributes to low level FPGA drivers the right way. Add attribute groups pointers to structures that are used when registering a manager, bridge, or group. When the low level driver registers, set the device attribute group. The attributes are created in device_add.
