Linus Torvalds 2779759c09 i2c for v7.2
Two major cleanup across drivers and core code:
  - use named initializers in device ID tables
  - replace dev_err() with dev_err_probe()
 
 Drivers:
 - at24: use named initializers for arrays of i2c_device_data
 - at91: add MCHP_LAN966X_PCI dependency
 - cadence: add shutdown callback
 - k1: enable by default on SpacemiT
 - mxs: improve documentation
 - qcom-geni: use pm_runtime_force_suspend/resume for system sleep
 - tegra:
    - disable fair arbitration on non-MCTP buses
    - allocate DMA buffers from the correct DMA device
 - designware:
    - handle active target shutdown cleanly
    - add shutdown callbacks for platform and PCI drivers
    - adopt the new PM_RUNTIME_ACQUIRE() helpers
 
 DT bindings:
 - convert davinci bindings to DT schema
 
 Core and muxes:
 - acpi: report missing I2C resources as -ENOENT
 - gpiolib: add gpiod_is_single_ended() helper for I2C GPIO users
 - i2c-mux-reg: add generic firmware node support
 - a set of 10 patches from Johan Hovold fixing adapter
   registration races, cleanup paths and resource management
   issues
 
 New support:
 - DesignWare LECA0003 (ACPI ID)
 - Loongson LS2K0300 I2C controller (new driver)
 - Qualcomm CCI Glymur and Shikra compatibles

Pull i2c updates from Andi Shyti:
 "This pull request is mostly made of cleanups and small infrastructure
  improvements across the I2C core, drivers and bindings. It also adds
  support for three drivers and a few new compatibles.
