But if the -u2port only supports device mode, and no IDDIG pin is provided, -setting otg_sel may cause failure of detection by host. -So set it only for dual-role mode. - -Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> -Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> ---- - drivers/usb/mtu3/mtu3_core.c | 9 +++++++-- - 1 file changed, 7 insertions(+), 2 deletions(-) - ---- a/drivers/usb/mtu3/mtu3_core.c -+++ b/drivers/usb/mtu3/mtu3_core.c -@@ -115,7 +115,9 @@ static int mtu3_device_enable(struct mtu - mtu3_clrbits(ibase, SSUSB_U2_CTRL(0), - (SSUSB_U2_PORT_DIS | SSUSB_U2_PORT_PDN | - SSUSB_U2_PORT_HOST_SEL)); -- mtu3_setbits(ibase, SSUSB_U2_CTRL(0), SSUSB_U2_PORT_OTG_SEL); -+ -+ if (mtu->ssusb->dr_mode == USB_DR_MODE_OTG) -+ mtu3_setbits(ibase, SSUSB_U2_CTRL(0), SSUSB_U2_PORT_OTG_SEL); - - return ssusb_check_clocks(mtu->ssusb, check_clk); - } -@@ -130,7 +132,10 @@ static void mtu3_device_disable(struct m - - mtu3_setbits(ibase, SSUSB_U2_CTRL(0), - SSUSB_U2_PORT_DIS | SSUSB_U2_PORT_PDN); -- mtu3_clrbits(ibase, SSUSB_U2_CTRL(0), SSUSB_U2_PORT_OTG_SEL); -+ -+ if (mtu->ssusb->dr_mode == USB_DR_MODE_OTG) -+ mtu3_clrbits(ibase, SSUSB_U2_CTRL(0), SSUSB_U2_PORT_OTG_SEL); -+ - mtu3_setbits(ibase, U3D_SSUSB_IP_PW_CTRL2, SSUSB_IP_DEV_PDN); - } - |
