usb: add device connection/disconnection detection

2015-05-15T00:49:33+00:00

Provide a function to detect USB device insertion/removal in order to
avoid having to do USB enumeration in a tight loop when trying to detect
peripheral hotplugging.

Propagate the error returned by submit_control_msg() rather then always
returning -EIO when the hcd code indicates an error.

Add the required #ifdefs and remove unwanted data structures so that the
USB uclass will be able to use this file.

dm: usb: Complete the splitting up of usb_new_device()

2015-04-18T17:11:21+00:00

This function now calls usb_setup_device() to set up the device and
usb_hub_probe() to check if it is a hub. The XHCI special case is now a
parameter to usb_setup_device(). The latter will be used by the USB uclass
when it is added, since it does not rely on any CONFIGs or legacy data
structures.

dm: usb: Split out more code from usb_new_device()

2015-04-18T17:11:21+00:00

Move the code that sets up the device with a new address into its own
function, usb_prepare_device().

dm: usb: Move descriptor setup code into its own function

2015-04-18T17:11:21+00:00

usb_new_device() is far too long and does far too much. As a first step, move
the code that does initial setup and reads a descriptor into its own function
called usb_setup_descriptor().

For XHCI the init order is different - we set up the device but don't
actually read the descriptor until after we set an address. Support this
option as a parameter to usb_setup_descriptor().

Avoid changing this torturous code more than necessary to make it easy to
review.
