From: yi1 . li
Date: Fri Jun 16 2017 - 19:04:30 EST


From: Yi Li <yi1.li@xxxxxxxxxxxxxxx>

Changes in v3:

- Add a platform device to enable PM support in test driver
- Add a debugfs device to enable driver data cache testing
- Fix a logic error so driver_data can be able to cache
- Add two test cases for caching and non-caching
- Rebase to Luis R. Rodriguez's 20170605-driver-data branch

Changes in v2:

- Rebase to Luis R. Rodriguez's 20170501-driver-data-try2
branch
- Expose DRIVER_DATA_REQ_NO_CACHE flag to public
driver_data_req_params structure, so upper drivers can ask
driver_data driver to bypass the internal caching mechanism.
This will be used for streaming and other drivers maintains
their own caching like iwlwifi.
- Add self test cases.


Yi Li (3):
firmware_class: move NO_CACHE from private to driver_data_req_params
iwlwifi: use DRIVER_DATA_REQ_NO_CACHE for driver_data
test: add no_cache to driver_data load tester
