When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Additional testing of the changes introduced in commit 33e06dcbe57a "common:
usb-hub: Reset hub port before scanning") revealed that some USB 2.0 and 3.0
flash drives didn't work in U-Boot on some Allwinner SoCs that support USB
2.0 interfaces only. More precisely, some of the tested USB 2.0 and 3.0
flash drives failed to be detected and work on an OrangePi Zero 3, based on
the Allwinner H616 SoC that supports USB 2.0 only, while the same USB flash
drives worked just fine on a Pine64 H64, based on the Allwinner H6 SoC that
supports both USB 2.0 and USB 3.0 interfaces.
The USB ID of the above-mentioned USB 3.0 flash drive that failed to work is
1f75:0917 (Innostor Technology Corporation IS917 Mass storage), it is 32 GB
in size and sold under the PNY brand. The mentioned USB 2.0 drive is some
inexpensive no-name drive with an invalid USB ID.
Resetting USB 3.0 hubs only, which this patch introduces to the USB hub
resets, has been tested to work as expected, resolving the identified issues
on the Allwinner H616, while not introducing any new issues on other tested
Allwinner SoCs. Thus, let's fix it that way.
According to the USB 3.0 specification, resetting a USB 3.0 port is required
when an attached USB device transitions between different states, such as
when it resumes from suspend. Though, the Linux kernel performs additional
USB 3.0 port resets upon initial USB device attachment, as visible in commit
07194ab7be63 ("USB: Reset USB 3.0 devices on (re)discovery") in the kernel
source, to ensure proper state of the USB 3.0 hub port and proper USB mode
negotiation during the initial USB device attachment and enumeration.
These additional types of USB port resets don't exist for USB 2.0 hubs,
according the USB 2.0 specification. The resets seem to be added to the USB
3.0 specification as part of the port and device mode negotiation.
The Linux kernel resets USB 3.0 (i.e. SuperSpeed) hubs only, as visible in
commit 10d674a82e55 ("USB: When hot reset for USB3 fails, try warm reset.")
in the kernel source. The check for SuperSpeed hubs is performed in a way
that also applies to newer SuperSpeed Plus (USB 3.1 or 3.2) hubs as well,
which hopefully makes it future proof.

Currently when a hub is turned on, all the ports are powered on.
This works well for hubs which have individual power control.
For the hubs without individual power control this has no effect.
Mostly in these scenarios the hub port is powered before the USB
controller is enabled, this can lead to some devices in unexpected
state.
With this patch, we explicitly reset the port while powering up hub
This resets the port for hubs without port power control and has
no effect on hubs with port power control as the port is still off.
Before this patch AMicro AM8180 based NVME to USB adapter won't be
detected as a USB3.0 Mass Storage device but with this it works as
expected.
Tested working after this patch:
1. AMicro AM8180 based NVME to USB Adapter
2. Kingston DataTraveler 3.0
3. GenesysLogic USB3.0 Hub
The drives were tested while connected directly and via the hub.

Add a new CONFIG_USB_HUB_DEBOUNCE_TIMEOUT to increase the
HUB_DEBOUNCE_TIMEOUT value, for example to 2s because some usb device
needs around 1.5s or more to make the hub port status to be
connected steadily after being powered off and powered on.
This 2s value is aligned with Linux driver and avoids to configure
"usb_pgood_delay" as a workaround for connection timeout on
some USB device; normally the env variable "usb_pgood_delay" is used
to delay the first query after power ON and thus the device answer,
but this variable not used to increase the connection timeout delay.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

One of these is malloc.h which we thus end up including in every file in

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

When usb_hub_reset_devices is called, it should be passed both an
indicator which hub it should operate on and what port number (local
to that hub) should be reset.
Previously, the usb_hub.c code did not include such context and
always started resets from port number 1, performing multiple
reset-requests for the same devices:
/*
* Reset any devices that may be in a bad state when applying
* the power. This is a __weak function. Resetting of the devices
* should occur in the board file of the device.
*/
for (i = 0; i < dev->maxchild; i++)
usb_hub_reset_devices(i + 1);
This adds an additional 'hub' parameter to usb_hub_reset_devices
that provides the context to fully qualify the port-number in.
Existing implementations are changed to accept and ignore the new
parameter.

During usb_hub_port_connect_change(), a port reset set feature
request is issued to the port, and later a port reset clear feature
is done to the same port before the function returns. However at
the end of usb_scan_port(), we attempt to clear port reset again
on a cached port status change variable, which should not be done.

It was observed that on Intel MinnowMax board, when xHCI is enabled
in the BayTrail SoC, with a USB 3.0 device connected to the bottom
USB 3.0 port (mapped to xHCI root port #7), its PORTSC register is
always 0x201203 (CCS = 1, CSC = 0). The root cause of such behavior
is unknown yet. Connect status change bit is set on the same port
with a USB 2.0 device (mapped to xHCI port #1, which is a different
port on the root hub).
With current logic in usb_scan_port(), the enumeration process will
abort if it does not detect a connect status change on a hub port.
However since a device connection status is correctly reported, the
enumeration process can still continue.
With this change, USB device connected to the bottom blue port on
MinnowMax board can be enumerated under either SS or HS mode.

This patch changes the USB port scanning procedure and timeout
handling in the following ways:
a)
The power-on delay in usb_hub_power_on() is now reduced to a value of
max(100ms, "hub->desc.bPwrOn2PwrGood * 2"). The code does not wait
using mdelay, instead usb_hub_power_on() will wait before querying
the device in the scanning loop later. The total timeout for this
hub, which is 1 second + "hub->desc.bPwrOn2PwrGood * 2" is calculated
and will be used in the following per-port scanning loop as the timeout
to detect active USB devices on this hub.
b)
Don't delay the minimum delay (for power to stabilize) in
usb_hub_power_on(). Instead skip querying these devices in the scannig
loop until the delay time is reached.
c)
The ports are now scanned in a quasi parallel way. The current code did
wait for each (unconnected) port to reach its timeout and only then
continue with the next port. This patch now changes this to scan all
ports of all USB hubs quasi simultaneously. For this, all ports are added
to a scanning list. This list is scanned until all ports are ready
by either a) reaching the connection timeout (calculated earlier), or
by b) detecting a USB device. This results in a faster USB scan time as
the recursive scanning of USB hubs connected to the hub that's currently
being scanned will start earlier.
One small functional change to the original code is, that ports with
overcurrent detection will now get rescanned multiple times
(PORT_OVERCURRENT_MAX_SCAN_COUNT).

Start with a short USB hub reset delay of 20ms. This can be enough for
some configurations.
The 2nd delay at the end of the loop is completely removed. Since the
delay hasn't been long enough, a longer delay time of 200ms is assigned
and will be used in the next loop round.
This hub reset handling is also used in the v4.4 Linux USB driver,
