Subject: [PATCH v7 21/29] fpga: dfl: add fpga region platform driver for FME
Date: Sat, 30 Jun 2018 08:53:28 +0800 [thread overview]
Message-ID: <1530320016-24712-22-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1530320016-24712-1-git-send-email-hao.wu@intel.com>
This patch adds fpga region platform driver for FPGA Management Engine.
It register an fpga region with given fpga manager / bridge device.

v3: rename driver to fpga-dfl-fme-region
fix fpga_mgr_put order problem in remove function.
rebased due to fpga api changes.
v4: rename to dfl-fme-region, fix SPDX license issue
include dfl-fme-pr.h instead of dfl-fme.h and dfl.h
add Acked-by from Alan and Moritz
v5: rebase, due to fpga region api changes.
v6: rebase and fix copyright time.
v7: fix kbuild issue.
