daab59ac05 avr32: Retire AVR32 for good
AVR32 is gone. It's already more than two years for no support in Buildroot,
even longer there is no support in GCC (last version is heavily patched 4.2.4).

Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).

There is no good point to keep this support in U-Boot either.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

7c22e26ec5 sunxi: musb: Re-init musb controller on repeated probe calls
With sunxi-musb musb_lowlevel_init() can fail when a charger; or no cable
is plugged into the otg port.

To avoid leaking the struct musb allocated by musb_init_controller()
on repeated musb_usb_probe() calls, we were caching its result.
But musb_init_controller() does more, such as calling sunxi_musb_init()
which enables the clocks.

Not calling sunxi_musb_init() causes the musb controller to stop working
after a "usb reset" since that calls musb_usb_remove() which disables the
clocks.

This commit fixes this by removing the caching of the struct returned
from musb_init_controller(), it replaces this by free-ing the allocated
memory in musb_usb_remove() and calling musb_usb_remove() on
musb_usb_probe() errors to ensure proper cleanup.

While at it also make musb_usb_probe() and musb_usb_remove() static.

ac3abf0b7d usb: musb: Fix hub port setting for SPLIT transactions
The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:

8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.

Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.

The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.

As they only seem to be referenced by u8500 based boards. Without any

If someone still wants to use this platform, then please send patches

c9f8947e66 sunxi: usb-phy: Never power off the usb ports
USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.

Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.

This patch removes the powering off calls, fixing the undesirable power
bouncing.

Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

09e7ea47e7 musb: Add device-model support to the musb-host u-boot glue
Add device-model support to the musb-host u-boot glue, note this only
adds device-model support to the musb-core glue code, it does not add
support for device-model to any of the SoC specific musb glue code.

e740ca3cab musb: Update usb-compat to work with struct usb_device without a parent ptr
When building with CONFIG_DM_USB=y struct usb_device does not have a parent
pointer. This commit adds support to the musb code to deal with this.

1583723638 musb: Allow musb_platform_enable to return an error code
Allow musb_platform_enable to return an error code and propagate it up to
usb_lowlevel_init().

This allows moving the checks for an external vbus being present to be
moved from platform_init to platform_enable, so that the user can unplug a
charger, plug in a host adapter with a usb-device, do a "usb reset" and
have things working.

This also allows adding a check for the id-pin to platform_enable, so that
it can short circuit the 1s delay in usb_lowlevel_init() when no host cable
is plugged in and thus waiting for a device to show up is useless.

Note that all the changes to code shared with the kernel are wrapped in
the kernel.

8802f56349 usb: Add an usb_device parameter to usb_reset_root_port
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 .
