b475bf0ec4 phy: qcom-snps: Correct the FSEL_MASK
The FSEL_MASK which selects the refclock is defined incorrectly.
It should be [4:6] not [5:7]. Due to this incorrect definition, the BIT(7)
in USB2_PHY_USB_PHY_HS_PHY_CTRL_COMMON0 is reset which keeps PHY analog
blocks ON during suspend.
Fix this issue by correctly defining the FSEL_MASK.

26f71abef5 phy: qcom-qmp: another fix for the sc8180x PCIe definition
Commit f839f14e24 ("phy: qcom-qmp: Add sc8180x PCIe support") added
SC8180X PCIe tables, but used sm8250_qmp_pcie_serdes_tbl as a serdes
table because of the copy paste error. Commit bfccd9a71a ("phy:
qcom-qmp: Fix sc8180x PCIe definition") corrected part of this mistake
by pointing serdes_tbl to sc8180x_qmp_pcie_serdes_tbl, however the
serdes_tbl_num field was not updated to use sc8180x table. So let's now
fix the serdes_tbl_num field too.

Add support to output received reference clock. Model the received
reference clock as an alternate parent of reference clock driver
clock. When received refclk is selected to output on cmn_refclk_p/m,
this is the internal reference clock driven on the pma_cmn_refclk_int.

2f5e9f815a phy: stm32: add phy tuning support
It can be necessary to adjust the phys settings to compensate parasitics.
This patch adds support of new optional properties to configure the tune
interface of the phys of stm32-usbphyc.
Properties are optional, that's why each property is skipped if not
found (-EINVAL).
Phy tuning is restored on resume because if deep low power state is
achieved, phy tuning configuration is reset.

With the conversion of rockchip-usb-phy.yaml a long time used fallback

the GRF phy address range, however the u-boot driver rockchip_usb2_phy.c
does. The bits in GRF_UOC0_CON2 for rk3066a/rk3188 and rk3288 for example
don't match. Remove the usb-phy fallback string for rk3066a/rk3188
to prevent possible strange side effects.

16b0314aa7 dma-buf: move dma-buf symbols into the DMA_BUF module namespace
In order to better track where in the kernel the dma-buf code is used,
put the symbols in the namespace DMA_BUF and modify all users of the
symbols to properly import the namespace to not break the build at the
same time.

Now the output of modinfo shows the use of these symbols, making it
easier to watch for users over time:

Use sysfs_emit instead of scnprintf or sprintf makes more sense.

interconnect changes for 5.16

Here are the changes for the 5.16-rc1 merge window consisting of just
driver updates. The highlight is the refactoring of some existing drivers
into common code and expanding some macros that will make adding QoS
support much easier.

Driver changes:
- icc-rpm: move bus clocks handling into qnoc_probe
- sdm660: expand DEFINE_QNODE macros
- sdm660: drop default/unused values
- sdm660: merge common code into icc-rpm
- icc-rpm: add support for QoS reg offset
- msm8916: expand DEFINE_QNODE macros
- msm8916: add support for AP-owned nodes

7cc2f34e1f fsi: sbefifo: Use interruptible mutex locking
Some SBE operations have extremely large responses and can require
several minutes to process the response. During this time, the device
lock must be held. If another process attempts an operation, it will
wait for the mutex for longer than the kernel hung task watchdog
allows. Therefore, use the interruptible function to lock the mutex.

Previously for the putsram and attn commands, only 32 words would have

SBE FFDC might be up to 8Kb.

The SBE interface expects data to be specified in units of words (4

This change allows the full FFDC capture to be implemented, where before
it was not available.

8d81b2a38d arm64: errata: Add detection for TRBE write to out-of-range
Arm Neoverse-N2 and Cortex-A710 cores are affected by an erratum where
the trbe, under some circumstances, might write upto 64bytes to an
address after the Limit as programmed by the TRBLIMITR_EL1.LIMIT.
This might -
  - Corrupt a page in the ring buffer, which may corrupt trace from a
    previous session, consumed by userspace.
  - Hit the guard page at the end of the vmalloc area and raise a fault.

To keep the handling simpler, we always leave the last page from the
range, which TRBE is allowed to write. This can be achieved by ensuring
that we always have more than a PAGE worth space in the range, while
calculating the LIMIT for TRBE. And then the LIMIT pointer can be
adjusted to leave the PAGE (TRBLIMITR.LIMIT -= PAGE_SIZE), out of the
TRBE range while enabling it. This makes sure that the TRBE will only
write to an area within its allowed limit (i.e, [head-head+size]) and
we do not have to handle address faults within the driver.

fa82d0b4b8 arm64: errata: Add workaround for TSB flush failures
Arm Neoverse-N2 (#2067961) and Cortex-A710 (#2054223) suffers
from errata, where a TSB (trace synchronization barrier)
fails to flush the trace data completely, when executed from
a trace prohibited region. In Linux we always execute it
after we have moved the PE to trace prohibited region. So,
we can apply the workaround every time a TSB is executed.

The work around is to issue two TSB consecutively.

NOTE: This errata is defined as LOCAL_CPU_ERRATUM, implying
that a late CPU could be blocked from booting if it is the
first CPU that requires the workaround. This is because we
do not allow setting a cpu_hwcaps after the SMP boot. The
other alternative is to use "this_cpu_has_cap()" instead
of the faster system wide check, which may be a bit of an
overhead, given we may have to do this in nvhe KVM host
before a guest entry.

b9d216fcef arm64: errata: Add detection for TRBE overwrite in FILL mode
Arm Neoverse-N2 and the Cortex-A710 cores are affected
by a CPU erratum where the TRBE will overwrite the trace buffer
in FILL mode. The TRBE doesn't stop (as expected in FILL mode)
when it reaches the limit and wraps to the base to continue
writing upto 3 cache lines. This will overwrite any trace that
was written previously.

Add the Neoverse-N2 erratum(#2139208) and Cortex-A710 erratum
(#2119858) to the detection logic.

This will be used by the TRBE driver in later patches to work
around the issue. The detection has been kept with the core
arm64 errata framework list to make sure :
  - We don't duplicate the framework in TRBE driver
  - The errata detection is advertised like the rest
    of the CPU errata.

Note that the Kconfig entries are not fully active until the
TRBE driver implements the work around.

8ac33b8b68 counter: Fix use-after-free race condition for events_queue_size write
A race condition is possible when writing to events_queue_size where the
events kfifo is freed during the execution of a kfifo_in(), resulting in
a use-after-free. This patch prevents such a scenario by protecting the
events queue in operation with a spinlock and locking before performing
the events queue size adjustment.

The existing events_lock mutex is renamed to events_out_lock to reflect
that it only protects events queue out operations. Because the events
queue in operations can occur in an interrupt context, a new
events_in_lock spinlock is introduced and utilized.
