Change to retrieve Setup packet by the copy which is readily copied from H/W register in ISR Signed-off-by: Chun-Chieh Li <[email protected]>
Some SoC series allow USB function to be disabled temporarily on unplug, and then enabled back on re-plug. Add support for such configuration option in DT and UDC driver. Signed-off-by: Chun-Chieh Li <[email protected]>
For HSUSBD, Control transfer with Data OUT stage will break. This is caused by FIFO flush which cannot be done timely even though in Setup token interrupt handler. For this, error recovery with FIFO is not done in Setup token/packet handler and rely on USB reset handler to do it as catch-all. Signed-off-by: Chun-Chieh Li <[email protected]>
With USBD and HSUSBD re-organized, SoC must have USBD and HSUSBD at the same time to pass compile. However, M2L31 just has USBD and meets compile error with HSUSBD unsupported. To avoid adding too many conditional (#if condition) code for the error, create one dummy HSUSBD device definition for M2L31 to pass compile. Signed-off-by: Chun-Chieh Li <[email protected]>
Add support for Nuvoton NuMaker M3331 series HSUSBD device driver Signed-off-by: Chun-Chieh Li <[email protected]>
Fix submit condition for non-control transfer. Do submit when any of the following conditions is met: 1. Transfer buffer (net_buf) is full 2. Last packet size is less than mps 3. Isochronous transfer USB mass may request C1 for sector size (512 bytes)-aligned and C2 for CBW (13 bytes). Signed-off-by: Chun-Chieh Li <[email protected]>
