Hi,
This patchset consists of some bug fixes and feature enhancements for
the dwc2 driver. All the patches are verified on dwc2 v3.0a with
dedicated fifos. Main focus of testing was with dma enabled. Although
basic testing without dma was also done.
This is based on testing/next branch in
Prepare to add more debug code. Moreover, don't save dentry * for
each file in struct dwc2_hsotg as clean up is done with
debugfs_remove_recursive(). s3c_hsotg_delete_debug() is removed
altogether for the same reason.
