This series fully update existing ISOC DDMA flow which initially based on 2 descriptor chains. Switching between desc chains performing based on BNA interrupt. Because of BNA interrupt few packets can be lost. 1/3 patch unmask ISOC IN BNA interrupt only. 2/3 patch changing ISOC IN/OUT flow as described above. 3/3 patch add High bandwidth ISOC OUT transfers support. All patches were tested on HAPS-DX7 platform using internal USB test tool. Changes from version 1: In patch 2/3 removed redundant warning print in dwc2_hsotg_ep_queue() (Zengtao (B) <prime.zeng@xxxxxxxxxxxxx>) In patch 2/3 replace loop counter from 'ret' to 'i' in dwc2_gadget_start_isoc_ddma() (Zengtao (B) <prime.zeng@xxxxxxxxxxxxx>) In patch 3/3 fix 2 kbuild test robot warnings. In patch 3/3 updated target_frame number width from 11-bit to 14-bit. In patches 2/3 and 3/3 updated all requests completion status codes to 0 instead of error codes (ENODATA, EIO, ETIMEDOUT). In case of errors, set request actual length to 0, to keep consistency with original code. Changes from version 0: Fix kbuild test robot warnings on idents.
