If so, once the dma interrupt comes, will request->actual be same with request->length in musb_g_tx? And if it is true, could we remove the check for 'is_dma'?
see that is_dma is set to true by just checking if dma in enabled in txcsr, it might be that dma didn't complete everything and you need to write txpktrdy by hand to send last short packet. So to remove that you would need to re-work a bit more code. You need to know when this is a dma IRQ or an endpoint IRQ. -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
