Merge tag 'i2c-7.3-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux

Pull i2c updates from Andi Shyti:
 "The main changes are support for shared SCL lines in i2c-gpio, a
  larger qcom-geni update covering tracing and transfer recovery and
  support for R-Car Gen5.

  The rest is mostly smaller driver, core and DT binding updates.

  Core and helpers:
   - support bus recovery with single-ended GPIOs
   - acpi: clean up resource handling
   - acpi: force ELAN1300 to 100 kHz
   - algo-bit: allow consumers to skip the optional bus test

  Drivers:
   - use generic bus frequency definitions in nomadik, octeon-core,
     microchip-corei2c, k1, davinci and pnx
   - i2c-gpio: support multiple buses sharing the same SCL line
   - qup: propagate clock enable failures
   - spacemit: configure SCL timing and clean up clock handling
   - amd-asf: guard against oversized firmware length

  qcom-geni:
   - add tracepoints for bus setup, interrupts and errors
   - use dedicated completion events for abort and reset
   - distinguish address and data NACK handling
   - cancel transfers before falling back to abort
   - simplify runtime PM and resource management
   - refactor resource and serial engine initialization

  DT bindings:
   - convert Altera bindings to DT schema
   - convert Axxia bindings to DT schema

  New support:
   - R-Car Gen5 and R-Car X5H
   - Axiado AX3005
   - Qualcomm Nord SA8797P
   - Qualcomm SA8255p"
