From: Chris Morgan <[email protected]> In order to get gadget mode functional (for fastboot and ums) I need to pull two patches in from mainline Linux. After applying these two patches to U-Boot I am able to use ums and fastboot on my Anbernic RG353P device for testing purposes.
Changes since V1: - Take the existing dwc3_core_soft_reset() function from the upstream Linux core.c file. This necessitates including another patch to add support from upstream Linux for the ip and version_type field and accompanying macros and functions to initialize it. - Specify the timeout changes made in the gadget driver as part of a separate patch and note the change is required. - Remove change in dwc3_ref_clk_period() as it was not intended to be included.
