dm: usb: Add a new USB controller operation 'update_hub_device'

2017-07-28T21:34:35+00:00

For USB host controllers like xHC, its internal representation of
hub needs to be updated after the hub descriptor is fetched. This
adds a new op that does this.

usb: hub: Use 'struct usb_hub_device' as hub device's uclass_priv

2017-07-28T21:34:29+00:00

Use USB hub device's dev->uclass_priv to point to 'usb_hub_device'
so that with driver model usb_hub_reset() and usb_hub_allocate()
are no longer needed.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

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.
