Xilinx Axi Watchdog driver conversion to driver model. All other changes are necessary for getting this done.

[PATCH 1/6] We no more need redundant io related macros [PATCH 2/6] Guard the board specific do_reset based on configuartions [PATCH 3/6] Cosmetic changes, based on checkpatch results [PATCH 4/6] Removed a bunch of WATCHDOG related macros [PATCH 5/6] Support for watchdog_reset function for Microblaze [PATCH 6/6] Last one, contains the Xilinx Axi watchdog driver to DM

Changes in v1: - Removed few macros which aren't needed anymore - Few cosmetic changes - Converted Xilinx Axi Watchdog driver to driver model

Shreenidhi Shedi (6): microblaze: Use default implementation from include/linux/io.h microblaze: Guard do_reset by CONFIG_SYSRESET microblaze: Cosmetic changes in Microblaze related files microblaze: Delete Xilinx watchdog related macros microblaze: Support for watchdog_reset in Microblaze init watchdog: Convert Xilinx Axi watchdog driver to driver model

Based on what I see on running microblaze system. Watchdog is started right after bitstream is loaded. It is weird that you want to stop watchdog which is not started yet. Also in case you can disable it because it was enabled in previous code you are no covering time between probe done and watchdog enabling again.

That's why I think you should remove this line.

Other then this the patch is fine and I have tested it on microblaze system.
