Pull i2c updates from Wolfram Sang: "New stuff from the I2C world: - in the core, getting irqs from ACPI is now similar to OF - new driver for MediaTek MT7621/7628/7688 SoCs - bcm2835, i801, and tegra drivers got some more attention - GPIO API cleanups - cleanups in the core headers - lots of usual driver updates" * 'i2c/for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (74 commits) i2c: mt7621: Fix platform_no_drv_owner.cocci warnings i2c: cpm: remove casting dma_alloc dt-bindings: i2c: sun6i-p2wi: Fix the binding example dt-bindings: i2c: mv64xxx: Fix the example compatible i2c: i801: Documentation update i2c: i801: Add support for Intel Tiger Lake i2c: i801: Fix PCI ID sorting dt-bindings: i2c-stm32: document optional dmas i2c: i2c-stm32f7: Add I2C_SMBUS_I2C_BLOCK_DATA support i2c: core: Tidy up handling of init_irq i2c: core: Move ACPI gpio IRQ handling into i2c_acpi_get_irq i2c: core: Move ACPI IRQ handling to probe time i2c: acpi: Factor out getting the IRQ from ACPI i2c: acpi: Use available IRQ helper functions i2c: core: Allow whole core to use i2c_dev_irq_from_resources eeprom: at24: modify a comment referring to platform data dt-bindings: i2c: omap: Add new compatible for J721E SoCs dt-bindings: i2c: mv64xxx: Add YAML schemas dt-bindings: i2c: sun6i-p2wi: Add YAML schemas i2c: mt7621: Add MediaTek MT7621/7628/7688 I2C driver ...
