mojyack 2291aa24f2 usb: refactor control request handling ... this commit is a combination of the following changes, which significantly refactors usb core and class drivers. 1. unify usb buffers of each class driver to reduce iram usage currently, many class drivers allocate their own buffer to receive control out data, which is a waste of iram. share one common buffer for that usage to address the issue. 2. simplify control request handling by implicitly receiving write request data packets change 1 above fixed the data destination. therefore, having the core receive the data allows us to reduce the class driver's work and simplifies the api. 3. enhance usb core's control request handling and unify the legacy driver api in order to implement change 2, both the legacy and new driver apis should be supported. so that, using the designware driver as a reference, the new driver api functionality is move into usb core. this simplifies the usb device drivers by requiring them to implement only the functionalities equivalent to the legacy api. tested with ipodvideo(arc) and erosqnative(designware) Change-Id: I3627daa90278751f599e2108ec150ec3f8f6c524		2026-05-25 12:42:36 +01:00
