USB: fix build on OMAPs if CONFIG_PM_RUNTIME is not set

2010-04-30T16:25:11+00:00

With patch as1329 (USB: convert to the runtime PM framework), we make USB_SUSPEND depend on PM_RUNTIME instead of CONFIG_PM. Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND. If PM_RUNTIME is not enabled, and we try to enable USB_OTG, we will end up with CONFIG_USB_SUSPEND selected. This is due to a known bug with the select statement. This makes the build break on various OMAP configs (which have CONFIG_USB_OTG set by default, but do not yet have CONFIG_PM_RUNTIME enabled). Avoid this by changing the logic for CONFIG_USB_OTG from "select USB_SUSPEND" to "depends on USB_SUSPEND" Signed-off-by: Anand Gadiyar CC: Michal Marek CC: Tony Lindgren CC: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: convert to the runtime PM framework

2010-03-02T22:54:12+00:00

This patch (as1329) converts the USB stack over to the PM core's runtime PM framework. This involves numerous changes throughout usbcore, especially to hub.c and driver.c. Perhaps the most notable change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME instead of CONFIG_PM. Several fields in the usb_device and usb_interface structures are no longer needed. Some code which used to depend on CONFIG_USB_PM now depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header files). The only visible change in behavior should be that following a system sleep (resume from RAM or resume from hibernation), autosuspended USB devices will be resumed just like everything else. They won't remain suspended. But if they aren't in use then they will naturally autosuspend again in a few seconds. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

Revert USB: usbfs: deprecate and hide option for !embedded

2009-07-12T22:16:39+00:00

This reverts commit cc71329b3b89b4a5be849b617f2c4f151f0b9213, so that Red Hat machines can boot properly. It seems that the Red Hat initrd code tries to watch the /proc/bus/usb/devices file to monitor usb devices showing up. While this task is prone to lots of races and does not show the true state of the system, they seem to like it. So for now, don't move this option under the EMBEDDED config option.

USB: usbfs: deprecate and hide option for !embedded

2009-06-16T04:44:41+00:00

Modern systems do not use usbfs; the entries within it are files, not device nodes, and do not support ACLs which are the default way to provide access to USB devices to untrusted users. It is replaced by device-nodes maintained by udev in /dev/bus/usb, libusb uses this device nodes. Mark the option as deprecated, and hide entirely for non-embedded builds (which may not be using udev but require raw USB device access).

USB: Remove EXPERIMENTAL from dynamic USB minor allocation.

2008-04-25T04:16:43+00:00

Since this USB feature seems non-experimental, remove that dependency. Signed-off-by: Robert P. J. Day Signed-off-by: Greg Kroah-Hartman

USB: partial USB embedded host support

2008-04-25T04:16:40+00:00

This provides better support for USB "Embedded Host" functionality, which is a subset of the USB OTG options: * External hub support can be disabled; * USB peripherals not whitelisted in "otg_whitelist.h" will be rejected during enumeration. These options can allow some savings in software and support. Signed-off-by: Robin Getz Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: remove CONFIG_USB_PERSIST setting

2008-04-25T04:16:32+00:00

This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.

USB: update Kconfig entry for USB_SUSPEND

2008-03-04T22:57:43+00:00

This patch (as1039) updates the Kconfig entry for USB_SUSPEND. The out-of-date reference to "power/state" is fixed, autosuspend is mentioned, and the dependency on EXPERIMENTAL is removed. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: always announce a device has been added to the system

2008-02-01T22:34:52+00:00

Distros (like SuSE) want to know this information, to make it easier to handle support issues. Might as well let everyone benefit from this. This is also enabled whenever CONFIG_USB_DEBUG is enabled, to help with debugging. Signed-off-by: Greg Kroah-Hartman
