Merge branch 'i2c/for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: - new driver for ICY, an Amiga Zorro card :) - axxia driver gained slave mode support, NXP driver gained ACPI - the slave EEPROM backend gained 16 bit address support - and lots of regular driver updates and reworks * 'i2c/for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (52 commits) i2c: tegra: Move suspend handling to NOIRQ phase i2c: imx: ACPI support for NXP i2c controller i2c: uniphier(-f): remove all dev_dbg() i2c: uniphier(-f): use devm_platform_ioremap_resource() i2c: slave-eeprom: Add comment about address handling i2c: exynos5: Remove IRQF_ONESHOT i2c: stm32f7: Make structure stm32f7_i2c_algo constant i2c: cht-wc: drop check because i2c_unregister_device() is NULL safe i2c-eeprom_slave: Add support for more eeprom models i2c: fsi: Add of_put_node() before break i2c: synquacer: Make synquacer_i2c_ops constant i2c: hix5hd2: Remove IRQF_ONESHOT i2c: i801: Use iTCO version 6 in Cannon Lake PCH and beyond watchdog: iTCO: Add support for Cannon Lake PCH iTCO i2c: iproc: Make bcm_iproc_i2c_quirks constant i2c: iproc: Add full name of devicetree node to adapter name i2c: piix4: Add ACPI support i2c: piix4: Fix probing of reserved ports on AMD Family 16h Model 30h i2c: ocores: use request_any_context_irq() to register IRQ handler i2c: designware: Fix optional reset error handling ...
