Pull VFIO updates from Alex Williamson:
"Various enablers for assignment of Intel graphics devices and future
support of vGPU devices (Alex Williamson). This includes
- Handling the vfio type1 interface as an API rather than a specific
implementation, allowing multiple type1 providers.
- Capability chains, similar to PCI device capabilities, that allow
extending ioctls. Extensions here include device specific regions
and sparse mmap descriptions. The former is used to expose non-PCI
regions for IGD, including the OpRegion (particularly the Video
BIOS Table), and read only PCI config access to the host and LPC
bridge as drivers often depend on identifying those devices.
Sparse mmaps here are used to describe the MSIx vector table, which
vfio has always protected from mmap, but never had an API to
explicitly define that protection. In future vGPU support this is
expected to allow the description of PCI BARs that may mix direct
access and emulated access within a single region.
- The ability to expose the shadow ROM as an option ROM as IGD use
cases may rely on the ROM even though the physical device does not
make use of a PCI option ROM BAR"

Add a new pseudo-board, within the existing SH boards/machine-vectors
framework, which does not represent any actual hardware but instead
requires all hardware to be described by the device tree blob provided
by the boot loader. Changes made are thus non-invasive and do not risk
breaking support for legacy boards.
New hardware, including the open-hardware J2 and associated SoC
devices, will use device free from the outset. Legacy SH boards can
transition to device tree once all their hardware has device tree
bindings, driver support for device tree, and a dts file for the
board.
It is intented that, once all boards are supported in the new
framework, the existing machine-vectors framework should be removed
and the new device tree setup code integrated directly.

Historically SH-2 Linux (and originally uClinux) used a syscall
calling convention incompatible with the established SH-3/4 Linux ABI.
This choice was made because the trap range used by the existing ABI,
0x10-0x17, overlaps with the hardware exception/interrupt trap range
reserved by SH-2, and in particular, with the SH-2A divide-by-zero and
division-overflow exceptions.
Despite the documented syscall convention using the low bits of the
trap number to signal the number of arguments the kernel should
expect, no version of the kernel has ever used this information, nor
is it useful; all of the registers need to be saved anyway. Therefore,
it is possible to pick a new trap number, 0x1f, that is both supported
by all existing SH-3/4 kernels and unassigned as a hardware trap in
the SH-2 range. This makes it possible to produce SH-2 application
binaries that are forwards-compatible with running on SH-3/4 kernels
and to treat SH as a unified platform with varying ISA support levels
rather than multiple gratuitously-incompatible platforms.
This patch adjusts the range checking SH-2 and SH-2A kernels make for
the syscall trap to accept the range 0x1f-0x2f rather than just
0x20-0x2f. As a result, trap 0x1f now acts as a syscall for all SH
models.

The generic header file is almost equivalent to the SH one. The
only difference is that the SH one supports allocating clkdev
lookups early using bootmem allocators instead of the slabs. From
what I can tell using visual inspection, the slab is initialized
before any clkdev allocation is made under arch/sh. So let's
remove the arch specific clkdev.h header and use the generic one
instead.

The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex. One of the
protected area by this mutex is hdmi_present_sense(). As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend. The buggy code path is like the following:
hdmi_unsol_event() -> ...
-> hdmi_present_sense()
==> ** here taking pcm_mutex
-> hdmi_present_sense_via_verbs()
-> snd_hda_power_up_pm() -> ... (runtime resume calls)
-> generic_hdmi_resume()
-> hdmi_present_sense()
==> ** here taking pcm_mutex again!
As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume. That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.
The patch also clarifies why this bug wasn't caught beforehand. We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side. However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

If mmc_blk_ioctl returns -EINVAL, blkdev_ioctl continues to
work without returning err to user-space. But now we check
CAP_SYS_RAWIO firstly, so we return -EPERM to blkdev_ioctl,
which make blkdev_ioctl return -EPERM to user-space directly.
So this will break all the ioctl with BLKROSET. Now we find
Android-adb suffer it for the following log:
remount of /system failed;
couldn't make block device writable: Operation not permitted
openat(AT_FDCWD, "/dev/block/platform/ff420000.dwmmc/by-name/system", O_RDONLY) = 3

We don't really need disable clk_ahb when failing to resume. Otherwise
we may take risk of bus error for accessing register without clk_ahb.

Normally the timeout clock frequency is read from the capabilities
register. It is also possible to set the value prior to calling
sdhci_add_host() in which case that value will override the
capabilities register value. However that was being done after
calculating max_busy_timeout so that max_busy_timeout was being
calculated using the wrong value of timeout_clk.
Fix that by moving the override before max_busy_timeout is
calculated.
The result is that the max_busy_timeout and max_discard
increase for BSW devices so that, for example, the time for
mkfs.ext4 on a 64GB eMMC drops from about 1 minute 40 seconds
to about 20 seconds.
Note, in the future, the capabilities setting will be tidied up
and this override won't be used anymore. However this fix is
needed for stable.

The header file asm/sizes.h is unnecessary, let's remove it.
This also allows to compile under X86 arch.

The Tegra30+ SDMMC module has memcomp pads that are used to
automatically find and set the correct drive strength settings to
the sdmmc pads. The calibration needs to be manually kicked off
when the card signal voltage is changed, after the card clock is
supplied again.

We've introduced a new helper in the MMC core:
mmc_regulator_set_vqmmc(). Let's use this in mtk-sd. Using this new
helper has some advantages:
1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
VQMMC and VMMC when the signal voltage is 3.3V. This ensures max
compatibility.
2. We get rid of a few more warnings when probing unsupported
voltages.
3. We get rid of some non-mediatek specific code in mtk-sd.

In commit ceae98f20e36 ("mmc: core: Try other signal levels
during power up") we can see that there are times when it's
valid to try several signal voltages. Don't print an ugly
error in the logs when that happens.

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE.
This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

The new code to do the clock rate setting externally to the SDMMC
module has a shortcut to not propagate changes with a 0 rate to
the CAR by simply bailing out. This breaks proper cutting of the
card clock. Fix it by directly calling the correct sdhci function.

value in core implementation
In control compatibility layer, when no elements are found by
ELEM_READ/ELEM_WRITE ioctl commands, ENXIO is returned. On the other hand,
in core implementation, ENOENT is returned. This is not good for
ALSA ctl applications.
This commit changes the return value from the compatibility layer so
that the same value is returned.

Commit e34d65696d2e ("stmmac: create of compatible mdio bus for stmmac
driver") broke DW GMAC functionality on ARC AXS10x boards:
That's what happens on eth0 up:
--------------------------->8------------------------
| libphy: PHY stmmac-0:ffffffff not found
| eth0: Could not attach to PHY
| stmmac_open: Cannot attach to PHY (error: -19)
--------------------------->8------------------------
Simplest solution is to add PHY description in board's .dts.
And so we do here.
