usb: musb-new: CONFIG_MUSB prefix replacement with CONFIG_USB_MUSB

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

USB-related options are usually prefixed with CONFIG_USB and platform-specific
adaptation for the MUSB controller already have a CONFIG_USB_MUSB prefix, so
this switches all MUSB-related options to a CONFIG_USB_MUSB prefix, for
consistency.

dm: usb: Adjust the USB_DEVICE() macro naming

2015-07-21T23:39:40+00:00

In Linux USB_DEVICE() is used to declare a USB device by vendor/device ID.
We should follow the same convention in U-Boot. Rename the existing
USB_DEVICE() macro to U_BOOT_USB_DEVICE() and bring in the USB_DEVICE()
macro from Linux for use in U-Boot.

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.

usb: Add an usb_device parameter to usb_reset_root_port

2015-07-21T23:39:35+00:00

Add an usb_device parameter to usb_reset_root_port so that it knows which
root-port it is resetting. This is necessary for proper device-model support
for usb_reset_root_port.

Also remove a duplicate declaration of usb_reset_root_port() from usb.h .

usb: usb_setup_device: Drop unneeded portnr function argument

2015-07-21T23:39:35+00:00

Drop the unneeded portnr function argument, the portnr is part of the
usb_device struct which is passed via the dev argument.

usb: Drop device-model specific copy of usb_legacy_port_reset

2015-07-21T23:39:34+00:00

The device-model usb_legacy_port_reset function calls the device-model
usb_port_reset function which is a 1 on 1 copy of the non dm
usb_legacy_port_reset and this is the only use of usb_port_reset in all
of u-boot.

Drop both, and alway use the usb_legacy_port_reset() version in
common/usb.c .

Also while at it make it static as it is only used in common/usb.c .

usb.h: Always declare usb function prototypes

2015-06-19T12:32:12+00:00

There is no harm in declaring the function prototypes even if nothing
implements them, and when CONFIG_DM_USB=y the various usb functions are
available regardless of any controller drivers being enabled.

This fixes compile warnings due to missing prototypes on ARCHs where
the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers.

One could argue that in the case of no controllers CONFIG_DM_USB should not
be set, but this problem is typically seen during bringup of boards which
do actually have usb controllers.

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.

dm: usb: Add support for companion controllers

2015-05-15T00:49:31+00:00

USB companion controllers must be scanned after the main controller has
been scanned, so that any devices which the main controller which to hand
over to the companion have actually been handed over before we scan the
companion.

As there are no guarantees that this will magically happen in the right
order, split the scanning of the buses in 2 phases, first main controllers,
and then companion controllers.
