Pull ARM SoC fixes from Arnd Bergmann:
"There are a few more PHY mode changes for allwinner SoC based boards
with a Realtek PHY after the driver changed its behavior, I assume
there will be more of these in the future. Also on for Allwinner, the
Banana Pi M2 board had a regression that led to some devices not
working because of a slightly incorrect voltage being applied.
By popular demand, I picked up a change from Krzysztof Kozlowski to
actually list the SoC tree in the MAINTAINERS file. We don't want to
get Cc'd on normal patches that are picked up by platform maintainers,
but the lack of an entry has led to confusion in the past.
All the other changes are fairly benign, fixing boot-time or
compile-time warning messages in various places:
- A dtc warning on the OLPC XO-1.75
- A boot-time warning on i.MX6 wandboard
- A harmless compile-time warning
- A regression causing one of the i.MX6 SoCs to be identified as
another
- Missing SoC identification of Allwinner V3 and S3"

This adds a new debugfs toggle ('bpf_bind_verifier_accept') that can be
used to make netdevsim reject BPF programs from being accepted by the
verifier. If this toggle (which defaults to true) is set to false,
nsim_bpf_verify_insn() will return EOPNOTSUPP on the last
instruction (after outputting the 'Hello from netdevsim' verifier message).
This makes it possible to check the verification callback in the driver
from test_offload.py in selftests, since the verifier now clears the
verifier log on a successful load, hiding the message from the driver.

Since commit 7f0a838254bd ("bpf, xdp: Maintain info on attached XDP BPF
programs in net_device"), the XDP program attachment info is now maintained
in the core code. This interacts badly with the xdp_attachment_flags_ok()
check that prevents unloading an XDP program with different load flags than
it was loaded with. In practice, two kinds of failures are seen:
- An XDP program loaded without specifying a mode (and which then ends up
in driver mode) cannot be unloaded if the program mode is specified on
unload.
- The dev_xdp_uninstall() hook always calls the driver callback with the
mode set to the type of the program but an empty flags argument, which
means the flags_ok() check prevents the program from being removed,
leading to bpf prog reference leaks.
The original reason this check was added was to avoid ambiguity when
multiple programs were loaded. With the way the checks are done in the core
now, this is quite simple to enforce in the core code, so let's add a check
there and get rid of the xdp_attachment_flags_ok() callback entirely.

Mistakenly the buffers (input and output) become enabled together for a short
period of time during GPIO request. This is problematic, because instead of
initial motive to disable them in the commit af7e3eeb84e2
("pinctrl: intel: Disable input and output buffer when switching to GPIO"),
the driven value on the pin, which might be used as an IRQ line, brings
firmwares of some touch pads to an awkward state that needs a full power off
to recover. Fix this, as stated in the culprit commit, by disabling the buffers.

When do suspend/resume test, there have WARN_ON() log dump from
stmmac_xmit() funciton, the code logic:
entry = tx_q->cur_tx;
first_entry = entry;
WARN_ON(tx_q->tx_skbuff[first_entry]);
In normal case, tx_q->tx_skbuff[txq->cur_tx] should be NULL because
the skb should be handled and freed in stmmac_tx_clean().
But stmmac_resume() reset queue parameters like below, skb buffers
may not be freed.
tx_q->cur_tx = 0;
tx_q->dirty_tx = 0;
So free tx skb buffer in stmmac_resume() to avoid warning and
memory leak.

Don't try to adjust XFRM support flags if the bond device isn't yet
registered. Bad things can currently happen when netdev_change_features()
is called without having wanted_features fully filled in yet. This code
runs both on post-module-load mode changes, as well as at module init
time, and when run at module init time, it is before register_netdevice()
has been called and filled in wanted_features. The empty wanted_features
led to features also getting emptied out, which was definitely not the
intended behavior, so prevent that from happening.
Originally, I'd hoped to stop adjusting wanted_features at all in the
bonding driver, as it's documented as being something only the network
core should touch, but we actually do need to do this to properly update
both the features and wanted_features fields when changing the bond type,
or we get to a situation where ethtool sees:
esp-hw-offload: off [requested on]
I do think we should be using netdev_update_features instead of
netdev_change_features here though, so we only send notifiers when the
features actually changed.

This patch fixes the slice count computation algorithm
for calculating the slice count based on Peak pixel rate
and the max slice width allowed on the DSC engines.
We need to ensure slice count > min slice count req
as per DP spec based on peak pixel rate and that it is
greater than min slice count based on the max slice width
advertised by DPCD. So use max of these two.
In the prev patch we were using min of these 2 causing it
to violate the max slice width limitation causing a blank
screen on 8K@60.

We currently presume that the engine reset is successful, cancelling the
expired preemption timer in the process. However, engine resets can
fail, leaving the timeout still pending and we will then respond to the
timeout again next time the tasklet fires. What we want is for the
failed engine reset to be promoted to a full device reset, which is
kicked by the heartbeat once the engine stops processing events.

Before reseting the engine, we suspend the execution of the guilty
request, so that we can continue execution with a new context while we
slowly compress the captured error state for the guilty context. However,
if the reset fails, we will promptly attempt to reset the same request
again, and discover the ongoing capture. Ignore the second attempt to
suspend and capture the same request.

In the course of discovering and closing many races with context closure
and execbuf submission, since commit 61231f6bd056 ("drm/i915/gem: Check
that the context wasn't closed during setup") we started checking that
the context was not closed by another userspace thread during the execbuf
ioctl. In doing so we cancelled the inflight request (by telling it to be
skipped), but kept reporting success since we do submit a request, albeit
one that doesn't execute. As the error is known before we return from the
ioctl, we can report the error we detect immediately, rather than leave
it on the fence status. With the immediate propagation of the error, it
is easier for userspace to handle.

Commit 6726fbff19bf ("pinctrl: aspeed: Fix GPI only function problem.")
fixes access to GPIO banks T and U on the AST2600. Both banks contain
input-only pins and the GPIO pin function is named GPITx and GPIUx
respectively. Unfortunately the fix had a negative impact on GPIO banks
D and E for the AST2400 and AST2500 where the GPIO pass-through
functions take similar "GPI"-style names. The net effect on the older
SoCs was that when the GPIO subsystem requested a pin in banks D or E be
muxed for GPIO, they were instead muxed for pass-through mode.
Mistakenly muxing pass-through mode e.g. breaks booting the host on
IBM's Witherspoon (AC922) platform where GPIOE0 is used for FSI.
Further exploit the names in the provided expression structure to
differentiate pass-through from pin-specific GPIO modes.
This follow-up fix gives the expected behaviour for the following tests:
Witherspoon BMC (AST2500):
1. Power-on the Witherspoon host
2. Request GPIOD1 be muxed via /sys/class/gpio/export
3. Request GPIOE1 be muxed via /sys/class/gpio/export
4. Request the balls for GPIOs E2 and E3 be muxed as GPIO pass-through
("GPIE2" mode) via a pinctrl hog in the devicetree
Rainier BMC (AST2600):
5. Request GPIT0 be muxed via /sys/class/gpio/export
6. Request GPIU0 be muxed via /sys/class/gpio/export
Together the tests demonstrate that all three pieces of functionality
(general GPIOs via 1, 2 and 3, input-only GPIOs via 5 and 6, pass-through
mode via 4) operate as desired across old and new SoCs.

For when managed interrupts are used (and shost->nr_hw_queues is set), a
fixed queue - set per-device - is still used for internal I/Os.
If all the CPUs mapped to that queue are offlined, then the completions for
that queue are not serviced and any internal I/Os will time out.
Fix by selecting a queue for internal I/Os from the queue mapped from the
current CPU in this scenario.
This is still not ideal as it does not deal with CPU hotplug for inflight
internal I/Os, and needs proper support from [0].

When queuing I/O request to LLD, STS_RESOURCE may be returned because:
- Host is in recovery or blocked
- Target queue throttling or target is blocked
- LLD rejection
In these scenarios BLK_STS_DEV_RESOURCE is returned to the block layer to
avoid an unnecessary re-run of the queue. However, all of the requests
queued to this SCSI device may complete immediately after reading
'sdev->device_busy' and BLK_STS_DEV_RESOURCE is returned to block layer. In
that case the current I/O won't get a chance to get queued since it is
invisible at that time for both scsi_run_queue_async() and blk-mq's
RESTART.
Fix the issue by not returning BLK_STS_DEV_RESOURCE in this situation.

The R9A06G032 clock driver uses an array of packed structures to reduce
kernel size. However, this array contains pointers, which are no longer
aligned naturally, and cannot be relocated on PPC64. Hence when
compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g.
PowerPC allyesconfig), the following warnings are produced:
WARNING: 136 bad relocations
c000000000616be3 R_PPC64_UADDR64 .rodata+0x00000000000cf338
c000000000616bfe R_PPC64_UADDR64 .rodata+0x00000000000cf370
...
Fix this by dropping the __packed attribute from the r9a06g032_clkdesc
definition, trading a small size increase for portability.
This increases the 156-entry clock table by 1 byte per entry, but due to
the compiler generating more efficient code for unpacked accesses, the
net size increase is only 76 bytes (gcc 9.3.0 on arm32).

This issue can be reproduced by having a kernel config with
CONFIG_IMX_MBOX=m and CONFIG_MXC_CLK_SCU=m. It's caused by the Makefile
wanting to build clk-scu.o and clk-imx8qxp.o as different targets but
that doesn't work (e.g. MXC_CLK_SCU = y while CLK_IMX8QXP = n)
"obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o clk-imx-lpcg-scu.o
clk-imx-scu-$(CONFIG_CLK_IMX8QXP) += clk-scu.o clk-imx8qxp.o"
Having MXC_CLK_SCU=y/m while CLK_IMX8QXP=n will cause a linker problem
like below:
LD [M] drivers/clk/imx/clk-imx-scu.o
arm-poky-linux-gnueabi-ld: no input files
Make MXC_CLK_SCU be un-selectable by users so it can only be selected by
the CLK_IMX8QXP option, ensuring the two symbols are built together.
Drop COMPILE_TEST too because this option isn't selectable anymore. We
can remove it from MXC_CLK_SCU because CLK_IMX8QXP selects MXC_CLK_SCU
which already has COMPILE_TEST.
