Merge tag 'i2c-for-7.1-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "The biggest news in this pull request is that it will start the last
  cycle of me handling the I2C subsystem. From 7.2. on, I will pass
  maintainership to Andi Shyti who has been maintaining the I2C drivers
  for a while now and who has done a great job in doing so.

  We will use this cycle for a hopefully smooth transition. Thanks must
  go to Andi for stepping up! I will still be around for guidance.

  Updates:
   - 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
   - various minor improvements in other drivers

  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"
