From c65c4f052bc3b67989bf54914798513685c54988 Mon Sep 17 00:00:00 2001 From: Mian Yousaf Kaukab Date: Sat, 16 May 2015 22:33:36 +0200 Subject: usb: gadget: net2280: fix use of GPEP in both directions USB3380 enhanced mode allows GPEP to be used in both IN and OUT directions. However, IN and OUT endpoints must use same USB endpoint address (bEndpointAddress). Fix this by setting the ep_cfg.ep_number during initialization and keep it in net2280_enable() Tested-by: Ricardo Ribalda Delgado Signed-off-by: Mian Yousaf Kaukab Signed-off-by: Felipe Balbi --- include/linux/usb/usb338x.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/linux/usb') diff --git a/include/linux/usb/usb338x.h b/include/linux/usb/usb338x.h index f92eb635b9d3..11525d8d89a7 100644 --- a/include/linux/usb/usb338x.h +++ b/include/linux/usb/usb338x.h @@ -43,6 +43,10 @@ #define IN_ENDPOINT_TYPE 12 #define OUT_ENDPOINT_ENABLE 10 #define OUT_ENDPOINT_TYPE 8 +#define USB3380_EP_CFG_MASK_IN ((0x3 << IN_ENDPOINT_TYPE) | \ + BIT(IN_ENDPOINT_ENABLE)) +#define USB3380_EP_CFG_MASK_OUT ((0x3 << OUT_ENDPOINT_TYPE) | \ + BIT(OUT_ENDPOINT_ENABLE)) struct usb338x_usb_ext_regs { u32 usbclass; -- cgit v1.2.3
