Subject: [PATCH v2 0/4] Modularization of DFL private feature drivers
Date: Fri, 24 Jul 2020 10:09:11 +0800	[thread overview]
Message-ID: <1595556555-9903-1-git-send-email-yilun.xu@intel.com> (raw)

This patchset makes it possible to develop independent driver modules
for DFL private features. It also helps to leverage existing kernel
drivers to enable some IP blocks in DFL.

Patch #1: An improvement of feature id definition. The feature id will be used
	  as the key field for dfl device/driver matching.
Patch #2: Release the dfl mmio regions after enumeration, so that private
	  feature drivers could request mmio region in their own drivers.
Patch #3: Introduce the dfl bus, then dfl devices could be supported by
	  independent dfl drivers.
Patch #4: An example of the dfl driver for N3000 nios private feature.


Main changes from v1:
- Add the new Patch #1, to improve the feature id definition.
- Change the dfl bus uevent format.
- Change the dfl device's sysfs name format.
- refactor dfl_dev_add()
- Add the Patch #4 as an example of the dfl driver.
- A lot of minor fixes for comments from Hao and Tom.

Xu Yilun (4):
  fpga: dfl: change data type of feature id to u16
  fpga: dfl: map feature mmio resources in their own feature drivers
  fpga: dfl: create a dfl bus type to support DFL devices
  fpga: dfl: add support for N3000 nios private feature
