dm: Use dm_scan_fdt_dev() directly where possible

2016-07-27T20:15:54+00:00

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07+00:00

This new function is more convenient for callers, and handles pre-relocation
situations automatically.

dm: usb: Unbind old block devices when shutting down USB

2016-03-18T03:27:39+00:00

When 'usb start' is used, block devices are created for any USB flash sticks
and disks, etc. When 'usb stop' is used, these block devices are currently
not removed.

We don't want old block devices hanging around since they can still be
visible to U-Boot. Therefore, when USB is shut down, remove and unbind all
the block devices created by the USB subsystem.

Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.

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.
