change being the renaming from "master/slave" to
 "controller/target" to adhere to I2C v7 and SMBus 3.2 standards.
 
 New Support:
 
  - Added support for Intel Arrow Lake-H.
  - Added I2C support in the Arioha SoC by linking the Mediatek
    I2C controller.
 
 Cleanups:
 
  - Added the MODULE_DESCRIPTION() macro, resolving a modpost
    warning in the ALi 1563 Southbridge driver.
  - Constified the regmap_config declaration in the i2c-designware
    driver.
  - Improved the coding style in the Renesas R-Car driver by
    removing unnecessary semicolons after brackets.
 
 General improvements:
 
  - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
    RUNTIME_PM_OPS to enable waking up the controller during
    suspend() before suspend_noirq() kicks in.
  - Improved logging in the Xilinx driver.
  - Added a warning (WARN()) in the Renesas R-Car driver for
    spurious interrupts.
 
 DTS Changes:
 
  - Removed address-cell and size-cell from the Atmel at91sam,
    nVidia Tegra 20, and Samsung S3c2410 devices.
  - Fixed Texas Instruments OMAP4 I2C controller to comply with
    the i2c-controller.yaml schema.
  - Improved indentation in DTS examples for several I2C devices.
  - Converted the NXP LPC1788 binding to the dt-schema.
  - Added documentation for the compatible string
    thead,th1520-i2c.
  - Added the "power-domains" property for the Meson I2C driver.

<DEVNAME>:<n>.<n>[,options]
Use the specified serial port on the serial core bus.
The addressing uses DEVNAME of the physical serial port
device, followed by the serial core controller instance,
and the serial port instance. The options are the same
as documented for the ttyS addressing above.
The mapping of the serial ports to the tty instances
can be viewed with:
$ ls -d /sys/bus/serial-base/devices/*:*.*/tty/*
/sys/bus/serial-base/devices/00:04:0.0/tty/ttyS0
In the above example, the console can be addressed with
console=00:04:0.0. Note that a console addressed this
way will only get added when the related device driver
is ready. The use of an earlycon parameter in addition to
the console may be desired for console output early on.

NXP I2C controller for LPC2xxx/178x/18xx/43xx
Required properties:
- compatible: must be "nxp,lpc1788-i2c"
- reg: physical address and length of the device registers
- interrupts: a single interrupt specifier
- clocks: clock for the device
- #address-cells: should be <1>
- #size-cells: should be <0>
Optional properties:
- clock-frequency: the desired I2C bus clock frequency in Hz; in
absence of this property the default value is used (100 kHz).
Example:
i2c0: i2c@400a1000 {
compatible = "nxp,lpc1788-i2c";
reg = <0x400a1000 0x1000>;
interrupts = <18>;
clocks = <&ccu1 CLK_APB1_I2C0>;
#address-cells = <1>;
#size-cells = <0>;
};
&i2c0 {
clock-frequency = <400000>;
lm75@48 {
compatible = "nxp,lm75";
reg = <0x48>;
