Merge tag 'i2c-for-6.11-rc1-try2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c fixes from Wolfram Sang: "The I2C core gains documentation updates for the testunit, a cleanup regarding unneeded 'driver_data' and more sanity checks in the char device. For the host drivers, 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. AT24 EEPROM driver changes: - add support for two new Microchip models - document even more new models in DT bindings (those use fallback compatibles so no code changes)" * tag 'i2c-for-6.11-rc1-try2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (87 commits) i2c: document new callbacks in i2c_algorithm dt-bindings: i2c: amlogic,meson6-i2c: add optional power-domains dt-bindings: i2c: at91: Add sama7d65 compatible string i2c: st: reword according to newest specification i2c: cpm: reword according to newest specification i2c: virtio: reword according to newest specification i2c: nvidia-gpu: reword according to newest specification i2c: viai2c: reword according to newest specification i2c: viperboard: reword according to newest specification i2c: uniphier: reword according to newest specification i2c: uniphier-f: reword according to newest specification i2c: tiny-usb: reword according to newest specification i2c: thunderx-pcidrv: reword according to newest specification i2c: tegra-bpmp: reword according to newest specification i2c: taos-evm: reword according to newest specification i2c: sun6i-p2wi: reword according to newest specification i2c: stm32f4: reword according to newest specification i2c: sprd: reword according to newest specification i2c: sis5595: reword according to newest specification i2c: rzv2m: reword according to newest specification ...
