Merge tag 'i2c-host-7.1-part1' of... 

Merge tag 'i2c-host-7.1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow

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

i2c Controller on XScale platforms such as IOP3xx and IXP4xx



Required properties:

- compatible : Must be one of

  "intel,iop3xx-i2c"

  "intel,ixp4xx-i2c";

- reg

- #address-cells = <1>;

- #size-cells = <0>;



Optional properties:

- Child nodes conforming to i2c bus binding



Example:



i2c@c8011000 {

	compatible = "intel,ixp4xx-i2c";

	reg = <0xc8011000 0x18>;

	interrupts = <33 IRQ_TYPE_LEVEL_LOW>;
