From 41a8b2c56470b7e4e3e2db93324d50bbbf60cdc4 Mon Sep 17 00:00:00 2001 From: Wu Hao Date: Sat, 30 Jun 2018 08:53:12 +0800 Subject: fpga: region: add compat_id support This patch introduces a compat_id pointer member and sysfs interface for each fpga region, similar as compat_id for fpga manager, it allows applications to read the per region compat_id for compatibility checking before other actions on this fpga-region (e.g. PR).
