[PATCHv3 0/3] Enable no_cache in driver_data

Show all headers | View raw

From: Yi Li <yi1.li@linux.intel.com>

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
