into arm/drivers
This pull request contains Broadcom SoCs drivers changes for 5.12,
please pull the following:
- Rafal adds support for the Power Management Bus (PMB) which is used in
a variety of DSL/Cable modem/STB SoCs with a primary target being the
4908 Wi-Fi SoC from the DSL organization. He also adds empty stubs to
get the chip identification (family and revision) to permit the
Broadcom STB USB PHY driver from being decoupled from ARCH_BRCMSTB
- Florian removes an unused function and its header

The USB Communications Capable bit indicates if port
partner is capable of communication over the USB data lines
(e.g. D+/- or SS Tx/Rx). Notify the status of the bit to low
level drivers to perform chip specific operation.
For instance, low level driver enables USB switches on D+/D-
lines to set up data path when the bit is set.

When executing a tracepoint, the tracepoint's func is dereferenced twice -
in __DO_TRACE() (where the returned pointer is checked) and later on in
__traceiter_##_name where the returned pointer is dereferenced without
checking which leads to races against tracepoint_removal_sync() and
crashes.
This adds a check before referencing the pointer in tracepoint_ptr_deref.

All amba drivers return 0 in their remove callback. Together with the
driver core ignoring the return value anyhow, it doesn't make sense to
return a value here.
Change the remove prototype to return void, which makes it explicit that
returning an error value doesn't work as expected. This simplifies changing
the core remove callback to return void, too.

The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct i3c_driver::remove() return
void, too. This makes it obvious that returning an error code is
a bad idea and future driver authors cannot get that wrong.
Up to now there are no drivers with a remove callback, so there is no
need to adapt drivers.

Current PERF_SAMPLE_WEIGHT sample type is very useful to expresses the
cost of an action represented by the sample. This allows the profiler
to scale the samples to be more informative to the programmer. It could
also help to locate a hotspot, e.g., when profiling by memory latencies,
the expensive load appear higher up in the histograms. But current
PERF_SAMPLE_WEIGHT sample type is solely determined by one factor. This
could be a problem, if users want two or more factors to contribute to
the weight. For example, Golden Cove core PMU can provide both the
instruction latency and the cache Latency information as factors for the
memory profiling.
For current X86 platforms, although meminfo::latency is defined as a
u64, only the lower 32 bits include the valid data in practice (No
memory access could last than 4G cycles). The higher 32 bits can be used
to store new factors.
Add a new sample type, PERF_SAMPLE_WEIGHT_STRUCT, to indicate the new
sample weight structure. It shares the same space as the
PERF_SAMPLE_WEIGHT sample type.
Users can apply either the PERF_SAMPLE_WEIGHT sample type or the
PERF_SAMPLE_WEIGHT_STRUCT sample type to retrieve the sample weight, but
they cannot apply both sample types simultaneously.
Currently, only X86 and PowerPC use the PERF_SAMPLE_WEIGHT sample type.
- For PowerPC, there is nothing changed for the PERF_SAMPLE_WEIGHT
sample type. There is no effect for the new PERF_SAMPLE_WEIGHT_STRUCT
sample type. PowerPC can re-struct the weight field similarly later.
- For X86, the same value will be dumped for the PERF_SAMPLE_WEIGHT
sample type or the PERF_SAMPLE_WEIGHT_STRUCT sample type for now.
The following patches will apply the new factors for the
PERF_SAMPLE_WEIGHT_STRUCT sample type.
The field in the union perf_sample_weight should be shared among
different architectures. A generic name is required, but it's hard to
abstract a name that applies to all architectures. For example, on X86,
the fields are to store all kinds of latency. While on PowerPC, it
stores MMCRA[TECX/TECM], which should not be latency. So a general name
prefix 'var$NUM' is used here.

The partner's PD revision may be resolved later than the port partner
registration since the port partner creation may take place once
Type-C detects the port has changed state, but before PD communication is
completed.
Add a setter so that the partner's PD revision can be attached to it once
it becomes available.
If the revision is set to a valid version (not 0), the setter will also
refresh the partner's usb_pd flag and notify on "supports_usb_power_delivery"
sysfs property as well.

The USB Power Delivery specification Section 6.2.1.1.5 outlines
revision backward compatibility requirements starting from Revision 3.0.
The Port, the Cable Plug, and the Port Partner may support either
revision 2 or revision 3 independently, and communication between ports,
partners, and cables of different revisions are allowed under rules
that the parties agree to communicate between each other using the
lowest common operating revision.
This may mean that Port-to-Partner operating revision comms may be
different than Port-to-CablePlug operating revision comms. For example,
it is possible for a R3.0 port to communicate with a R3.0 partner
using R3.0 messages, while the R3.0 port (in the same session) must
communicate with the R2.0 cable using R2.0 messages only.
Introduce individual revision number properties for cable
and port partner so that the port can track them independently.

In preparation for adding CQHCI crypto engine (inline encryption)
support, add the code required to make mmc_core and mmc_block aware of
inline encryption. Specifically:
- Add a capability flag MMC_CAP2_CRYPTO to struct mmc_host. Drivers
will set this if the host and driver support inline encryption.
- Embed a blk_keyslot_manager in struct mmc_host. Drivers will
initialize this (as a device-managed resource) if the host and driver
support inline encryption. mmc_block registers this keyslot manager
with the request_queue of any MMC card attached to the host.
- Make mmc_block copy the crypto keyslot and crypto data unit number
from struct request to struct mmc_request, so that drivers will have
access to them.
- If the MMC host is reset, reprogram all the keyslots to ensure that
the software state stays in sync with the hardware state.

Add a resource-managed variant of blk_ksm_init() so that drivers don't
have to worry about calling blk_ksm_destroy().
Note that the implementation uses a custom devres action to call
blk_ksm_destroy() rather than switching the two allocations to be
directly devres-managed, e.g. with devm_kmalloc(). This is because we
need to keep zeroing the memory containing the keyslots when it is
freed, and also because we want to continue using kvmalloc() (and there
is no devm_kvmalloc()).

At PMIC subsystem, C89 comments are preferred over C99.
While here, also update the copyrights of the header file.

Remove the IRQ list from the header, as this is used only
inside the driver itself. Also, get rid of two unused
defines.
The net result is that only struct hi6421_spmi_pmic remains
on it, as this is used by the regulator driver.

- When referring to regmap, rename map to regmap
- inside hi6421-spmi-pmic, call private data struct as
ddata.
No functional changes.

Instead of doing its own SPMI I/O implementation, use the
already-existing regmap one.

rx_callback is a standard mailbox callback mechanism and could
cover the function of proprietary cmdq_task_cb, so it is better
to use the standard one instead of the proprietary one. But
register rx_callback should before mbox_request_channel(),
so remove cmdq_pkt_flush() and let client driver implement
its own synchronous flush.

When exporting NFS, we may as well use the real change attribute
returned by the original server instead of faking up a change attribute
from the ctime.
Note we can't do that by setting I_VERSION--that would also turn on the
logic in iversion.h which treats the lower bit specially, and that
doesn't make sense for NFS.
So instead we define a new export operation for filesystems like NFS
that want to manage the change attribute themselves.

The sja1105 implementation can be blind about this, but the felix driver
doesn't do exactly what it's being told, so it needs to know whether it
is a TX or an RX VLAN, so it can install the appropriate type of TCAM
rule.
