Merge tag 'i2c-host-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow
This release includes significant updates, with the primary
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.
