Remove lagacy IPP driver
- This driver isn't used anymore so remove it. Marek is preparing new one
  which includes completely rewritten API so this driver will be replaced
  with the new version[1] later.
And cleanups.

- Refactoring topology code to prepare for dGPU support + fixes to that code
  - Add option to generate dummy/virtual CRAT table when its missing or deformed
  - Recognize CPUs other then APUs as compute entities
- Various clean ups and bug fixes

I have not yet sent the dGPU topology code because it depends on a patch
for the PCI subsystem that adds PCIe atomics support. Once that patch is
upstreamed we can continue with the rest of the dGPU code.

calling this function to keep a reference held on the clk and
call clk_prepare_enable() on it. We support this design in the

that instead.

3aa0582fdb of: platform: populate /firmware/ node from of_platform_default_populate_init()
Since "/firmware" does not have its own "compatible" property as it's
just collection of nodes representing firmware interface, it's sub-nodes
are not populated during system initialization.

Currently different firmware drivers search the /firmware/ node and
populate the sub-node devices selectively. Instead we can populate
the /firmware/ node during init to avoid more drivers continuing to
populate the devices selectively.

To generalize the solution this patch populates the /firmware/ node
explicitly from of_platform_default_populate_init().

dfe8266b8d sh_eth: fix TSU resource handling
When switching  the driver to the managed device API,  I managed to break
the  case of a  dual Ether devices sharing a single TSU: the 2nd Ether port
wouldn't probe. Iwamatsu-san has tried to fix this but his patch was buggy
and he then dropped the ball...

The solution is to  limit calling devm_request_mem_region() to the first
of  the two  ports  sharing the same TSU, so devm_ioremap_resource() can't
be used anymore for the TSU resource...

Pull ARM SoC fixes from Arnd Bergmann:
 "Fixes this time include mostly device tree changes, as usual, the
  notable ones include:

   - A number of patches to fix most of the remaining DTC warnings that
     got introduced when DTC started warning about some obvious
     mistakes. We still have some remaining warnings that probably may
     have to wait until 4.16 to get fixed while we try to figure out
     what the correct contents should be.

   - On Allwinner A64, Ethernet PHYs need a fix after a mistake in
     coordination between patches merged through multiple branches.

   - Various fixes for PMICs on allwinner based boards

   - Two fixes for ethernet link detection on some Renesas machines

   - Two stability fixes for rockchip based boards

  Aside from device-tree, two other areas got fixes for older problems:

   - For TI Davinci DM365, a couple of fixes were needed to repair the
     MMC DMA engine support, apparently this has been broken for a
     while.

   - One important fix for all Allwinner chips with the PMIC driver as a
     loadable module"

" The EEE feature is not supported when the MAC is configured to use the
TBI, RTBI, SMII, RMII or SGMII single PHY interface. Even if the MAC
supports multiple PHY interfaces, you should activate the EEE mode only
when the MAC is operating with GMII, MII, or RGMII interface."

82e07602d2 drm/i915: Pass DMA_ATTR_NO_WARN to dma_map_sg()
In some iommu, e.g. swiotlb, the available space can be quite limited.
So we employ a trial-and-error approach to seeing if our large
contiguous chunks can fit, and if that fails we try again with smaller
chunks after trying to free our own lazily allocated blobs. As we use a
trial-and-error approach, we do not want dma_map_sg() to emit a WARN of
its own accord, we want to gracefully report the error back to the caller
instead.

Note that our noisy culprit, swiotlb, doesn't honour the flag, yet.

Pull "Allwinner fixes for 4.15" from Chen-Yu Tsai:

First, one fix that adds proper regulator references for the EMAC
external PHYs on A64 boards. The EMAC bindings were developed for 4.13,
but reverted at the last minute. They were finalized and brought back
for 4.15. However in the time between, regulator support for the A64
boards was merged. When EMAC device tree changes were reintroduced,
this was not taken into account.

Second, a patch that adds OF based modalias uevent for RSB slave devices.
This has been missing since the introduction of RSB, and recently with
PMIC regulator support introduced for the A64, has been seen affecting
distributions, which have the all-important PMIC mfd drivers built as
modules, which then don't get loaded.

Other minor cleanups include final conversion of raw indices to CCU
binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the
A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero
Plus2, and adding a missing compatible for the PMIC on the TBS A711
tablet.

68198dca45 soc: Add SoC driver for Gemini
This adds an SoC driver for the Gemini. Currently there
is only one thing not fitting into any other framework,
and that is the bus arbitration setting.

All Gemini vendor trees seem to be setting this register to
exactly the same arbitration so we just add a small code
snippet to do this at subsys_init() time before any other
drivers kick in.

7b9faf5df0 vfb: fix video mode and line_length being set when loaded
Currently, when loading the vfb module, the newly created fbdev
has a line_length of 0, and its video mode would be PSEUDOCOLOR
regardless of color depth. (The former could be worked around by
calling the FBIOPUT_VSCREENINFO ioctl with having the FBACTIVIATE_FORCE
flag set.) This patch automatically sets the line_length correctly,
and the video mode is derived from the bit depth now as well.

Thanks to Geert Uytterhoeven for confirming the bug and helping me with
the patch.

f7a7535474 fbdev: pxa3xx: use ktime_get_ts64 for time stamps
do_gettimeofday() is deprecated because it is not y2038 safe, so I'm
changing the calculation for the diagnostic output over to using
'timespec64'.

We really only print time deltas here, so changing it to monotonic
time makes this more robust, the correct accessor for this is
ktime_get_ts64().

do_gettimeofday() is deprecated and a bit clumsy. This changes
radeon_probe_pll_params() over to using ktime_get() with monotonic
times. There is no need to check for negative values any more
since the monotonic clocksource cannot go backwards, but I'm
adding a check for zero-division in case of a bad clocksource.

Picking up the patch from Serhey Popovych (commit 191cdb3822,
"veth: Be more robust on network device creation when no attributes").

When the peer name attribute is not provided the former implementation tries
to register the given device name twice ... which leads to -EEXIST.
If only one device name is given apply an automatic generated and valid name
for the peer.

54e98b5d66 net: dsa: b53: Turn off Broadcom tags for more switches
Models such as BCM5395/97/98 and BCM53125/24/53115 and compatible require that
we turn on managed mode to actually act on Broadcom tags, otherwise they just
pass them through on ingress (host -> switch) and don't insert them in egress
(switch -> host). Turning on managed mode is simple, but requires us to
properly support ARL misses on multicast addresses which is a much more
involved set of changes not suitable for a bug fix for this release.

30414f3010 drm/i915: Apply Display WA #1183 on skl, kbl, and cfl
Display WA #1183 was recently added to workaround
"Failures when enabling DPLL0 with eDP link rate 2.16
or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz
(CDCLK_CTL CD Frequency Select 10b or 11b) used in this
 enabling or in previous enabling."

This workaround was designed to minimize the impact only
to save the bad case with that link rates. But HW engineers
indicated that it should be safe to apply broadly, although
they were expecting the DPLL0 link rate to be unchanged on
runtime.

We need to cover 2 cases: when we are in fact enabling DPLL0
and when we are just changing the frequency with small
differences.

This is based on previous patch by Rodrigo Vivi with suggestions
from Ville Syrjälä.

d72d72cd33 mmc:host:sdhci-pci:Addition of Arasan PCI Controller with integrated phy.
The Arasan Controller is based on a FPGA platform and has integrated phy
with specific registers used during initialization and
management of different modes. The phy and the controller are integrated
and registers are very specific to Arasan.

Arasan being an IP provider, licenses these IPs to various companies for
integration of IP in custom SOCs. The custom SOCs define own register
map depending on how bits are tied inside the SOC for phy registers,
depending on SOC memory plan and hence will require own platform drivers.

If more details on phy registers are required, an interface document is
hosted at https://arasan.com/NF/eMMC5.1 PHY Programming in Linux.pdf.
