Subject: [PATCH v7 04/29] fpga: mgr: add compat_id support
Date: Sat, 30 Jun 2018 08:53:11 +0800 [thread overview]
Message-ID: <1530320016-24712-5-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1530320016-24712-1-git-send-email-hao.wu@intel.com>
This patch introduces compat_id support to fpga manager, it adds
a fpga_compat_id pointer to fpga manager data structure to allow
fpga manager drivers to save the compatibility id. This compat_id
could be used for compatibility checking before doing partial
reconfiguration to associated fpga regions.
