usb: chipidea: Allow disabling streaming not only in udc mode

2013-01-21T19:44:34Z

commit 929473ea05db455ad88cdc081f2adc556b8dc48f upstream. When running a scp transfer using a USB/Ethernet adapter the following crash happens: $ scp test.tar.gz fabio@192.168.1.100:/home/fabio fabio@192.168.1.100's password: test.tar.gz 0% 0 0.0KB/s --:-- ETA ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x2cc/0x2f0() NETDEV WATCHDOG: eth0 (asix): transmit queue 0 timed out Modules linked in: Backtrace: [<80011c94>] (dump_backtrace+0x0/0x10c) from [<804d3a5c>] (dump_stack+0x18/0x1c) r6:000000ff r5:80412388 r4:80685dc0 r3:80696cc0 [<804d3a44>] (dump_stack+0x0/0x1c) from [<80021868>] (warn_slowpath_common+0x54/0x6c) [<80021814>] (warn_slowpath_common+0x0/0x6c) from [<80021924>] (warn_slowpath_fmt+0x38/0x40) ... Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem. However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode, so allow disabling streaming also in host mode. Tested on a mx6qsabrelite board.

usb: chipidea: permit driver bindings pass phy pointer

2012-07-09T16:59:23Z

Sometimes, the driver bindings may know what phy they use. For example, when using device tree, the usb controller may have a phandler pointing to usb phy. Signed-off-by: Richard Zhao Reviewed-by: Marek Vasut Acked-by: Felipe Balbi Tested-by: Subodh Nijsure Signed-off-by: Greg Kroah-Hartman

USB: Chipidea: rename struct ci13xxx_udc_driver to struct ci13xxx_platform_data

This patch rename struct ci13xxx_udc_driver and var with the type. ci13xxx_platform_data reflect it's passed from platfrom driver. Signed-off-by: Richard Zhao Reviewed-by: Felipe Balbi Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman

USB: CI13xxx: Use usb_put_hcd() on failure to drop HCD

2012-05-15T15:43:40Z

Use usb_put_hcd() call instead of usb_remove_hcd() as that's the appropriate call to drop hcd which failed registration. Signed-off-by: Marek Vasut Cc: Alan Stern Cc: Alexander Shishkin Cc: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: chipidea: add power_budget limit for ehci to platform data

usb: chipidea: add host role

2012-05-11T23:56:15Z

This adds EHCI host support to the chipidea driver. We want it to be part of the hdrc driver and not a standalone (sub-)driver module, as the structure of ehci-hcd.c suggests, so for chipidea controller we hack it to not provide platform-related code, but only the ehci hcd. The ehci-platform driver won't work for us here too, because the controller uses the same registers for both device and host mode and also otg-related bits, so it's not really possible to put ehci registers into a separate resource. This is not a pretty solution, but the alternative is exporting symbols from the chipidea driver to a ehci-chipidea driver and doing all the module refcounting.
