Pull ARM SoC fixes from Arnd Bergmann:
"The majority of the fixes this time are for OMAP hardware, here is a
breakdown of the significant changes:
Various device tree bug fixes:
- TI am57xx boards need a voltage level fix to avoid damaging SD
cards
- vf610-bk4 fails to detect its flash due to an incorrect description
- meson-g12a USB phy configuration fails
- meson-g12b reboot should not power off the SD card
- Some corrections for apparently harmless differences from the
documentation.
Regression fixes:
- ams-delta FIQ interrupts broke in 5.3
- TI am3/am4 mmc controllers broke in 5.2
The logic_pio driver (used on some Huawei ARM servers) got a few bug
fixes for reliability.
And a couple of compile-time warning fixes"

The driver does not support the SMBUS Quick command so remove the
flag that indicates that level of support.
By default the i2c_detect tool uses the quick command to try and
detect devices at some bus addresses. If the quick command is used
then we will not detect the device, even though it is present.

The IP datasheet says this controller is compatible with SD Host
Specification Version v4.00.
As it turned out, the ADMA of this IP does not work with 64-bit mode
when it is in the Version 3.00 compatible mode; it understands the
old 64-bit descriptor table (as defined in SDHCI v2), but the ADMA
System Address Register (SDHCI_ADMA_ADDRESS) cannot point to the
64-bit address.
I noticed this issue only after commit bd2e75633c80 ("dma-contiguous:
use fallback alloc_pages for single pages"). Prior to that commit,
dma_set_mask_and_coherent() returned the dma address that fits in
32-bit range, at least for the default arm64 configuration
(arch/arm64/configs/defconfig). Now the host->adma_addr exceeds the
32-bit limit, causing the real problem for the Socionext SoCs.
(As a side-note, I was also able to reproduce the issue for older
kernels by turning off CONFIG_DMA_CMA.)
Call sdhci_enable_v4_mode() to fix this.

The OCR register defines the supported range of VDD voltages for SD cards.
However, it has turned out that some SD cards reports an invalid voltage
range, for example having bit7 set.
When a host supports MMC_CAP2_FULL_PWR_CYCLE and some of the voltages from
the invalid VDD range, this triggers the core to run a power cycle of the
card to try to initialize it at the lowest common supported voltage.
Obviously this fails, since the card can't support it.
Let's fix this problem, by clearing invalid bits from the read OCR register
for SD cards, before proceeding with the VDD voltage negotiation.

Family 16h Model 30h SMBus controller needs the same port selection fix
as described and fixed in commit 0fe16195f891 ("i2c: piix4: Fix SMBus port
selection for AMD Family 17h chips")
commit 6befa3fde65f ("i2c: piix4: Support alternative port selection
register") also fixed the port selection for Hudson2, but unfortunately
this is not the exact same device and the AMD naming and PCI Device IDs
aren't particularly helpful here.
The SMBus port selection register is common to the following Families
and models, as documented in AMD's publicly available BIOS and Kernel
Developer Guides:
50742 - Family 15h Model 60h-6Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
55072 - Family 15h Model 70h-7Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
52740 - Family 16h Model 30h-3Fh (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS)
The Hudson2 PCI Device ID (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) is shared
between Bolton FCH and Family 16h Model 30h, but the location of the
SmBus0Sel port selection bits are different:
51192 - Bolton Register Reference Guide
We distinguish between Bolton and Family 16h Model 30h using the PCI
Revision ID:
Bolton is device 0x780b, revision 0x15
Family 16h Model 30h is device 0x780b, revision 0x1F
Family 15h Model 60h and 70h are both device 0x790b, revision 0x4A.
The following additional public AMD BKDG documents were checked and do
not share the same port selection register:
42301 - Family 15h Model 00h-0Fh doesn't mention any
42300 - Family 15h Model 10h-1Fh doesn't mention any
49125 - Family 15h Model 30h-3Fh doesn't mention any
48751 - Family 16h Model 00h-0Fh uses the previously supported
index register SB800_PIIX4_PORT_IDX_ALT at 0x2e

The de-init routine should be doing the following in order:-

2. Shut down the crtcs - failing to do this might cause a connector leakage
See the 'commit 109c4d18e574 ("drm/arm/malidp: Ensure that the crtcs are
shutdown before removing any encoder/connector")'
3. Disable the interrupts
4. Unbind the components
5. Free up DRM mode_config info

1. Re-ordered the header files inclusion
2. Rebased on top of the latest drm-misc-fixes

Currently, we don't call dma_set_max_seg_size() for i915 because we
intentionally do not limit the segment length that the device supports.
However, this results in a warning being emitted if we try to map
anything larger than SZ_64K on a kernel with CONFIG_DMA_API_DEBUG_SG
enabled:
[ 7.751926] DMA-API: i915 0000:00:02.0: mapping sg segment longer
than device claims to support [len=98304] [max=65536]
[ 7.751934] WARNING: CPU: 5 PID: 474 at kernel/dma/debug.c:1220
debug_dma_map_sg+0x20f/0x340
This was originally brought up on
https://bugs.freedesktop.org/show_bug.cgi?id=108517 , and the consensus
there was it wasn't really useful to set a limit (and that dma-debug
isn't really all that useful for i915 in the first place). Unfortunately
though, CONFIG_DMA_API_DEBUG_SG is enabled in the debug configs for
various distro kernels. Since a WARN_ON() will disable automatic problem
reporting (and cause any CI with said option enabled to start
complaining), we really should just fix the problem.
Note that as me and Chris Wilson discussed, the other solution for this
would be to make DMA-API not make such assumptions when a driver hasn't
explicitly set a maximum segment size. But, taking a look at the commit
which originally introduced this behavior, commit 78c47830a5cb
("dma-debug: check scatterlist segments"), there is an explicit mention
of this assumption and how it applies to devices with no segment size:
Conversely, devices which are less limited than the rather
conservative defaults, or indeed have no limitations at all
(e.g. GPUs with their own internal MMU), should be encouraged to
set appropriate dma_parms, as they may get more efficient DMA
mapping performance out of it.
So unless there's any concerns (I'm open to discussion!), let's just
follow suite and call dma_set_max_seg_size() with UINT_MAX as our limit
to silence any warnings.
Changes since v3:
* Drop patch for enabling CONFIG_DMA_API_DEBUG_SG in CI. It looks like
just turning it on causes the kernel to spit out bogus WARN_ONs()
during some igt tests which would otherwise require teaching igt to
disable the various DMA-API debugging options causing this. This is
too much work to be worth it, since DMA-API debugging is useless for
us. So, we'll just settle with this single patch to squelch WARN_ONs()
during driver load for users that have CONFIG_DMA_API_DEBUG_SG turned
on for some reason.
* Move dma_set_max_seg_size() call into i915_driver_hw_probe() - Chris
Wilson

We're not allowed to create new properties after device registration
so for MST connectors we need to either create the max_bpc property
earlier, or we reuse one we already have. Let's do the latter apporach
since the corresponding SST connector already has the prop and its
min/max are correct also for the MST connector.
The problem was highlighted by commit 4f5368b5541a ("drm/kms:

get_registers() blindly copies the memory written to by the
usb_control_msg() call even if the underlying urb failed.
This could lead to junk register values being read by the driver, since
some indirect callers of get_registers() ignore the return values. One
example is:
ocp_read_dword() ignores the return value of generic_ocp_read(), which
calls get_registers().
So, emulate PCI "Master Abort" behavior by setting the buffer to all
0xFFs when usb_control_msg() fails.

Commit d4c08afafa04 ("s390/qeth: streamline SNMP cmd code") removed
the bounds checking for req_len, under the assumption that the check in
qeth_alloc_cmd() would suffice.
But that code path isn't sufficiently robust to handle a user-provided
data_length, which could overflow (when adding the cmd header overhead)
before being checked against QETH_BUFSIZE. We end up allocating just a
tiny iob, and the subsequent copy_from_user() writes past the end of
that iob.
Special-case this path and add a coarse bounds check, to protect against
maliciuous requests. This let's the subsequent code flow do its normal
job and precise checking, without risk of overflow.
