[GIT PULL] i2c-host for v7.1, part 1

[Andi Shyti]

Hi Wolfram,

here's the first part of the merge window pull request.

It has the usual refactoring, cleanups and updates, with no big
surprises. There is also some new hardware support. The main
chunks this time are the xiic and rtl9300 work.

One patch is already queued for part 2, as it needed some
dependencies first and I will keep collecting patches with no
major impact.

Thanks and enjoy the rest of the weekend,
Andi

----------------------------------------------------------------
i2c-host for v7.1, part 1

- generic cleanups in npcm7xx, qcom-cci, xiic and designware DT
  bindings

- atr: use kzalloc_flex for alias pool allocation
- ixp4xx: convert bindings to DT schema
- ocores: use read_poll_timeout_atomic() for polling waits
- qcom-geni: skip extra TX DMA TRE for single read messages
- s3c24xx: validate SMBus block length before using it
- spacemit: refactor xfer path and add K1 PIO support
- tegra: identify DVC and VI with SoC data variants
- tegra: support SoC-specific register offsets
- xiic: switch to devres and generic fw properties
- xiic: skip input clock setup on non-OF systems

rtl9300:
- add per-SoC callbacks and clock support for RTL9607C
- add support for new 50 kHz and 2.5 MHz bus speeds
- general refactoring in preparation for RTL9607C support

New support:
- DesignWare GOOG5000 (ACPI HID)
- Intel Nova Lake (ACPI ID)
- Realtek RTL9607C
- SpacemiT K3 binding
- Tegra410 register layout support
