I tested the patchset. Here are the results: - VBUS switching I'm no longer getting any ID interrupts at all when I apply the patch below. The board stays in HOST mode all the time. If I configure it as peripheral, it works as peripheral. Note with [1], I was able to switch from Peripheral->Host , not the other way around. --- a/arch/arm/boot/dts/imx28-m28evk.dts +++ b/arch/arm/boot/dts/imx28-m28evk.dts @@ -240,6 +240,8 @@ ahb@80080000 { usb0: usb@80080000 { + dr_mode = "otg"; + phy_mode = "utmi"; vbus-supply = <®_usb0_vbus>; pinctrl-names = "default"; pinctrl-0 = <&usbphy0_pins_a>; --------------------------- - MX23 UDC issue I found a workaround. Now running 'dmesg' via telnet through USB CDC link no longer hangs the USB driver, but works as expected. I applied this small patch that enables the streaming mode. Works on MX23EVK. It's surprising this issue doesn't manifest on MX28, maybe MX28 contains a new revision of the controller. I remember there was some discussion about the streaming mode on MXS some time ago. diff --git a/drivers/usb/chipidea/ci_hdrc_imx.c b/drivers/usb/chipidea/ci_hdrc_imx.c index d06355e..bba8e25 100644 --- a/drivers/usb/chipidea/ci_hdrc_imx.c +++ b/drivers/usb/chipidea/ci_hdrc_imx.c @@ -92,8 +92,7 @@ static int ci_hdrc_imx_probe(struct platform_device *pdev) .name = "ci_hdrc_imx", .capoffset = DEF_CAPOFFSET, .flags = CI_HDRC_REQUIRE_TRANSCEIVER | - CI_HDRC_PULLUP_ON_VBUS | - CI_HDRC_DISABLE_STREAMING, + CI_HDRC_PULLUP_ON_VBUS, }; struct resource *res; int ret; [1] http://git.pengutronix.de/?p=mgr/linux.git;a=shortlog;h=refs/heads/v3.10/topic/usb- peterchen Best regards, Marek Vasut -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
