The HiKey 970 board is similar to Hikey 960 with regards
to its USB configutation: it also relies on a USB HUB
that is used when DWC3 is at host mode.
However, it requires a few extra DT settings, as it
uses a voltage regulator and GPIO reset pin.
Add support for them.

The HiKey960 has a fairly complex USB configuration due to it
needing to support a USB-C port for host/device mode and multiple
USB-A ports in host mode, all using a single USB controller.
See schematics here:
https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf
This driver acts as a usb-role-switch intermediary, intercepting
the role switch notifications from the tcpm code, and passing
them on to the dwc3 core.
In doing so, it also controls the onboard hub and power gpios in
order to properly route the data lines between the USB-C port
and the onboard hub to the USB-A ports.

On non-EFI systems, it wasn't possible to test the platform firmware
loader because it will have never set "checked_fw" during __init.
Instead, allow the test code to override this check. Additionally split
the declarations into a private symbol namespace so there is greater
enforcement of the symbol visibility.

Systems have a line for restting the remote CFAM. This is not part of
the FSI master, but is associated with it, so it makes sense to include
it in the master driver.
This exposes a sysfs interface to reset the cfam, abstracting away the
direction and polarity of the GPIO, as well as the timing of the reset
pulse. Userspace will be blocked until the reset pulse is finished.
The reset is hard coded to be in the range of (900, 1000) us. It was
observed with a scope to regularly be just over 1ms.
If the device tree property is not preset the driver will silently
continue.

For testing and hardware debugging a user may wish to override the
divisor at runtime. By setting fsi_master_aspeed.bus_div=N, the divisor
will be set to N, if 0 < N <= 0x3ff.
This is a module parameter and not a device tree option as it will only
need to be set when testing or debugging.

The exception is when wired externally with a cable, in which case we

Some FSI capable systems have internal FSI signals, and some have
external cabled FSI. Software can detect which machine this is by
reading a jumper GPIO, and also control which pins the signals are
routed to through a mux GPIO.
This attempts to find the GPIOs at probe time. If they are not present
in the device tree the driver will not error and continue as before.
The mux GPIO is owned by the FSI driver to ensure it is not modified at
runtime. The routing jumper obtained as non-exclusive to allow other
software to inspect it's state.

The driver ought to claim local bus ownership of the slave it's
communicating with.
This is for multi-master setups. The slave (in theory) will deny access
to masters who try to access the CFAM address space but who don't "own"
the bus.
As driver doesn't seem to perform any other teardown there is no need to
"un-claim" ownership at teardown. Also I'm not aware of any multi-master
setup using this driver so it shouldn't actually matter. Also, the
hardware doesn't seem to enforce this despite being required in the
specification...

Currently we allocate rx buffers in a single contiguous buffers for
headers (iser and iscsi) and data trailer. This means that most likely the
data starting offset is aligned to 76 bytes (size of both headers).
This worked fine for years, but at some point this broke, resulting in
data corruptions in isert when a command comes with immediate data and the
underlying backend device assumes 512 bytes buffer alignment.
We assume a hard-requirement for all direct I/O buffers to be 512 bytes
aligned. To fix this, we should avoid passing unaligned buffers for I/O.
Instead, we allocate our recv buffers with some extra space such that we
can have the data portion align to 512 byte boundary. This also means that
we cannot reference headers or data using structure but rather
accessors (as they may move based on alignment). Also, get rid of the
wrong __packed annotation from iser_rx_desc as this has only harmful
effects (not aligned to anything).
This affects the rx descriptors for iscsi login and data plane.

The device .release function was not being set during the device
initialization. This was leading to the below warning, in error cases when
put_srv was called before device_add was called.
Warning:
Device '(null)' does not have a release() function, it is broken and must
be fixed. See Documentation/kobject.txt.
So, set the device .release function during device initialization in the
__alloc_srv() function.

In the prepare_message callback the bus driver has the
opportunity to split a transfer into smaller chunks.
spi_map_msg is done after prepare_message.
Function spi_res_release releases the splited transfers
in the message. Therefore spi_res_release should be called
after spi_map_msg.
The previous try at this was commit c9ba7a16d0f1
which released the splited transfers after
spi_finalize_current_message had been called.
This introduced a race since the message struct could be
out of scope because the spi_sync call got completed.
Fixes this leak on spi bus driver spi-bcm2835.c when transfer
size is greater than 65532:

If something goes wrong (such as the SCL being stuck low) then we need
to reset the PCA chip. The issue with this is that on reset we lose all
config settings and the chip ends up in a disabled state which results
in a lock up/high CPU usage. We need to re-apply any configuration that
had previously been set and re-enable the chip.

Right now we are failing requests based on the controller state (which
is checked inline in nvmf_check_ready) however we should definitely
accept requests if the queue is live.
When entering controller reset, we transition the controller into
NVME_CTRL_RESETTING, and then return BLK_STS_RESOURCE for non-mpath
requests (have blk_noretry_request set).
This is also the case for NVME_REQ_USER for the wrong reason. There
shouldn't be any reason for us to reject this I/O in a controller reset.
We do want to prevent passthru commands on the admin queue because we
need the controller to fully initialize first before we let user passthru
admin commands to be issued.
In a non-mpath setup, this means that the requests will simply be
requeued over and over forever not allowing the q_usage_counter to drop
its final reference, causing controller reset to hang if running
concurrently with heavy I/O.
