Just as a heads up, I tried testing your tree with my HiKey960, and after fixing the compat string inconsistency, the drivers seem to load properly. However the drm_hwcomposer seems to have some trouble with the driver: 01-01 00:12:41.456 345 345 E hwc-drm-display-compositor: Commit test failed for display 0, FIXME 01-01 00:12:41.456 345 345 E hwc-drm-two: Failed to apply the frame composition ret=-22 01-01 00:12:41.456 351 351 E HWComposer: presentAndGetReleaseFences: present failed for display 0: BadParameter (4) I'll dig in a bit further as to why, but wanted to give you a heads up. thanks -john
