There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

A recent change to regmap breaks building of phycore-rk3288 for me. The
difference is only a few bytes. Somehow CI seems to pass, even though it
fails when I run docker locally. But it prevents me from sending any more
pull requests.
In any case this board is clearly near the limit. We could revert the
offending change, but it is needed for sandbox tests.
Instead, add a way to drop the range checks in SPL, since they end up
doing nothing if everything is working as expected.
This makes phycore-rk3288 build again for me and reduces the size of SPL
slightly for a number of boards.

When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.
On some boards, such as Khadas VIM3L and SEI610, this is not the case.
We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
# echo b > /proc/sysrq-trigger
In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.
Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.
Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).

For the TI SoCs affected by errata i2329, enable MDIO manual

Signed-off-by: Ravi Gunasekaran <r-gunasekaran@ti.com>
Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
In certain TI SoCs, on the CPSW and ICSS peripherals, there is
a possibility that the MDIO interface returns corrupt data on
MDIO reads or writes incorrect data on MDIO writes. There is also
a possibility for the MDIO interface to become unavailable until
the next peripheral reset.
The workaround is to configure the MDIO in manual mode and disable the
MDIO state machine and emulate the MDIO protocol by reading and writing
appropriate fields in MDIO_MANUAL_IF_REG register of the MDIO controller
to manipulate the MDIO clock and data pins.
More details about the errata i2329 and the workaround is available in:
