Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.

For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

Pull powerpc updates from Michael Ellerman:
 "Highlights include:

   - Support for the kexec_file_load() syscall, which is a prereq for
     secure and trusted boot.

   - Prevent kernel execution of userspace on P9 Radix (similar to
     SMEP/PXN).

   - Sort the exception tables at build time, to save time at boot, and
     store them as relative offsets to save space in the kernel image &
     memory.

   - Allow building the kernel with thin archives, which should allow us
     to build an allyesconfig once some other fixes land.

   - Build fixes to allow us to correctly rebuild when changing the
     kernel endian from big to little or vice versa.

   - Plumbing so that we can avoid doing a full mm TLB flush on P9
     Radix.

   - Initial stack protector support (-fstack-protector).

   - Support for dumping the radix (aka. Linux) and hash page tables via
     debugfs.

   - Fix an oops in cxl coredump generation when cxl_get_fd() is used.

   - Freescale updates from Scott: "Highlights include 8xx hugepage
     support, qbman fixes/cleanup, device tree updates, and some misc
     cleanup."

   - Many and varied fixes and minor enhancements as always.

Pull ARM 64-bit DT updates from Arnd Bergmann:
 "A couple of interesting new SoC platforms are now supported, these are
  the respective DTS sources:

   - Samsung Exynos5433 mobile phone platform, including an (almost)
     fully supported phone reference board.
   - Hisilicon Hip07 server platform and D05 board, the latest iteration
     of their product line, now with 64 Cortex-A72 cores across two
     sockets.
   - Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
     line, used in Android tablets and ultra-cheap development boards
   - NXP LS1046A Communication processor, improving on the earlier
     LS1043A with faster CPU cores
   - Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
     mobile phone SoCs
   - Early support for the Nvidia Tegra Tegra186 SoC
   - Amlogic S905D is a minor variant of their existing Android consumer
     product line
   - Rockchip PX5 automotive platform, a close relative of their popular
     rk3368 Android tablet chips

  Aside from the respective evaluation platforms for the above chips,
  there are only a few consumer devices and boards added this time:

   - Huawei Nexus 6P (Angler) mobile phone
   - LG Nexus 5x (Bullhead) mobile phone
   - Nexbox A1 and A95X Android TV boxes
   - Pine64 development board based on Allwinner A64
   - Globalscale Marvell ESPRESSOBin community board based on Armada 3700
   - Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive board

  For the existing platforms, we get bug fixes and new peripheral
  support for Juno, Renesas, Uniphier, Amlogic, Samsung, Broadcom,
  Rockchip, Berlin, and ZTE"

Pull i2c updates from Wolfram Sang:

 - the first series of making i2c_device_id optional instead of
   mandatory (in favor of alternatives like of_device_id).

   This involves adding a new probe callback (probe_new) which removes
   some peculiarities I2C had for a long time now. The new probe is
   matching the other subsystems now and the old one will be removed
   once all users are converted. It is expected to take a while but
   there is ongoing interest in that.

 - SMBus Host Notify introduced 4.9 got refactored. They are now using
   interrupts instead of the alert callback which solves multiple
   issues.

 - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux

 - significant refactoring for bcm2835 driver

Add per-Generation fallback bindings for R-Car SoCs.

This is in keeping with the compatibility string scheme is being adopted
for drivers for Renesas SoCs.

Also, improve readability by listing the rmobile fallback compatibility
string after the more-specific compatibility strings they provide a
fallback for.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

Also:
* Deprecate renesas,i2c-rcar. It seems poorly named as it is only
  compatible with R-Car Gen 1. It also appears unused in mainline.
* Add some text to describe per-SoC bindings
