dm: usb: Remove inactive children after a bus scan

2015-11-20T03:27:52+00:00

Each scan of the USB bus may return different results. Existing driver-model
devices are reused when found, but if a device no longer exists it will stay
around, de-activated, but bound.

Detect these devices and remove them after the scan completes.

dm: usb: Deprecate usb_get_dev_index()

2015-11-20T03:27:52+00:00

This function should not be used with driver model. While there are users
of USB Ethernet that use driver model for USB but not Ethernet, we have
to keep it around. Add a comment to that effect.

Revert "dm: usb: Use device_unbind_children to clean up usb devs on stop"

2015-11-20T03:27:51+00:00

This reverts commit 6cda369509e0d3fa5f9e33c9d71589c4523799fa.

We want to avoid having the USB stack rely on unbind.

dm: Rename dev_get_parentdata() to dev_get_parent_priv()

2015-10-23T15:42:28+00:00

The current name is inconsistent with other driver model data access
functions. Rename it and fix up all users.

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20+00:00

Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

usb: USB storage-specific part ifdef in uclass

2015-08-05T15:20:34+00:00

usb_stor_reset is only defined when USB storage support is enabled, thus the
function is not declared when such support is missing.

dm: usb: Do not assume that first child is always a hub

2015-07-21T23:39:36+00:00

On some single port (otg) controllers there is no emulated root hub, so
the first child (if any) may be one of: UCLASS_MASS_STORAGE,
UCLASS_USB_DEV_GENERIC or UCLASS_USB_HUB.

All three of these (and in the future others) are suitable for our
purposes, remove the check for the device being a hub, and add a check to
deal with the fact that there may be no child-dev.

dm: usb: Allow usb host drivers to implement usb_reset_root_port

2015-07-21T23:39:36+00:00

Allow usb uclass host drivers to implement usb_reset_root_port, this is
used by single port usb hosts which do not emulate a hub, such as otg
controllers.

dm: usb: Rename usb_find_child to usb_find_emul_child

2015-07-21T23:39:36+00:00

Now that we unbind usb devices from usb_stop() usb_find_child() is
only necessary to deal with emulated usb devices.

Rename it to make this clear and add a #ifdef to make it a nop in
other cases.

Note the #ifdef turns usb_find_emul_child() into a nop, rather then not
building it and adding another #ifdef to the caller, this is done this way
because adding a #ifdef to the caller is somewhat hairy.
