This requires that -we explicitly set TXPKTRDY for that transfer. - -However the musb_g_tx code will not set TXPKTRDY twice if the last -transfer is exactly equal to maxpacket, even if request->zero is set. -Using Mode 1 will solve this; a better fix might be in musb_g_tx(). - -Without this change, musb will not correctly send out a ZLP if the -last transfer is the maxpacket size and request->zero is set. - -Signed-off-by: Anand Gadiyar <gadiyar-l0cyMroinI0@public.gmane.org> -Signed-off-by: David Brownell <dbrownell-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org> ---- - drivers/usb/musb/musb_gadget.c | 2 +- - 1 files changed, 1 insertions(+), 1 deletions(-) - -diff --git a/drivers/usb/musb/musb_gadget.c b/drivers/usb/musb/musb_gadget.c -index bc197b2..e8f920c 100644 ---- a/drivers/usb/musb/musb_gadget.c -+++ b/drivers/usb/musb/musb_gadget.c -@@ -310,7 +310,7 @@ static void txstate(struct musb *musb, struct musb_request *req) - /* setup DMA, then program endpoint CSR */ - request_size = min(request->length, - musb_ep->dma->max_len); -- if (request_size <= musb_ep->packet_sz) -+ if (request_size < musb_ep->packet_sz) - musb_ep->dma->desired_mode = 0; - else - musb_ep->dma->desired_mode = 1; --- -1.6.0.4 - |
