The devm_gpiod_request_gpiod() call will add "-gpios" to
any passed connection ID before looking it up.
I do not think the reset GPIO on this platform is named
"reset-gpios-gpios" but rather "reset-gpios" in the device
tree, so fix this up so that we get a proper reset GPIO
handle.
Also drop the inclusion of the legacy GPIO header.

Pull yet more SPDX updates from Greg KH:
"Another round of SPDX header file fixes for 5.2-rc4
These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
added, based on the text in the files. We are slowly chipping away at
the 700+ different ways people tried to write the license text. All of
these were reviewed on the spdx mailing list by a number of different
people.
We now have over 60% of the kernel files covered with SPDX tags:
$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
Files checked: 64533
Files with SPDX: 40392
Files with errors: 0
I think the majority of the "easy" fixups are now done, it's now the
start of the longer-tail of crazy variants to wade through"

This driver does not support reading more than 255 bytes at once because
the register for storing the number of bytes to read is only 8 bits. Add
a max_read_len quirk to enforce this.
This was found when using this driver with the SFP driver, which was
previously reading all 256 bytes in the SFP EEPROM in one transaction.
This caused a bunch of hard-to-debug errors in the xiic driver since the
driver/logic was treating the number of bytes to read as zero.
Rejecting transactions that aren't supported at least allows the problem
to be diagnosed more easily.

Fix wrong order in probing routine initialization - field `base_addr'
is used before it's initialized. Move assignment of 'priv->base_addr`
to the beginning, prior the call to mlxcpld_i2c_read_comm().
Wrong order caused the first read of capability register to be executed
at wrong offset 0x0 instead of 0x2000. By chance it was a "good
garbage" at 0x0 offset.

Pull USB/PHY updates from Greg KH:
"Here is the big set of USB and PHY driver patches for 5.2-rc1
There is the usual set of:
- USB gadget updates
- PHY driver updates and additions
- USB serial driver updates and fixes
- typec updates and new chips supported
- mtu3 driver updates
- xhci driver updates
- other tiny driver updates
Nothing really interesting, just constant forward progress.
All of these have been in linux-next for a while with no reported

but both of them had been in linux-next before they got merged here

There are two problems with dev_err() here. One: It is not ratelimited.
Two: We don't see which driver tried to transfer something with a
suspended adapter. Switch to dev_WARN_ONCE to fix both issues. Drawback
is that we don't see if multiple drivers are trying to transfer while
suspended. They need to be discovered one after the other now. This is
better than a high CPU load because a really broken driver might try to
resend endlessly.

Some recent commits to this driver were trying to make sure the TSS
interrupt is not generated on busy system due to 25ms timer expiring
between commands. It can still happen, however if STOP command is not
issued on time at the end of the transmission. If wait_for_completion in
axxia_i2c_xfer_msg() would not return after 25ms of getting an
interrupt, TSS will be generated and idev->err_msg will be set to
-ETIMEDOUT which will be returned from the axxia_i2c_xfer_msg(), even
though the transfer did actually succeed (STOP is automatically issued
when TSS triggers).
Fortunately, apart from already used manual and sequence commands, the
controller also has so called auto command. It works just like manual
mode but it but an automatic STOP is issued when either transfer length
is met or NAK is received from slave device.
This patch changes the axxia_i2c_xfer_msg() function so that auto
command is used for last message in transaction letting hardware manage
issuing STOP. TSS is disabled just after command transferring last
message finishes. Auto command, just like sequence, ends with SS
interrupt instead of SNS so handling of both had to be unified.
The axxia_i2c_stop() is no longer needed as the transfer can only end
with following conditions:
- fully successful - then last message was send by AUTO command and STOP
was issued automatically
- NAK received - STOP is issued automatically by controller
- arbitration lost - STOP should not be issued as we don't control the
bus
- IP interrupt received - this is sent when transfer length is set to 0
for auto/sequence command. The check for that is done before START is
send so no STOP is required
- TSS received between commands - STOP is issued by the controller
