Pull i2c updates from Wolfram Sang: - new drivers for HPE GXP and Loongson 2K/LS7A - bigger refactorings for i801 and xiic - gpio driver gained ACPI and SDA-write only support - the core converted some OF helpers to fwnode helpers - usual bunch of driver updates * tag 'i2c-for-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (52 commits) MAINTAINERS: Add HPE GXP I2C Support i2c: Add GXP SoC I2C Controller dt-bindings: i2c: Add hpe,gxp-i2c i2c: xiic: Remove some dead code i2c: xiic: Add SCL frequency configuration support i2c: xiic: Update compatible with new IP version dt-bindings: i2c: xiic: Add 'xlnx,axi-iic-2.1' to compatible i2c: i801: Call i801_check_post() from i801_access() i2c: i801: Call i801_check_pre() from i801_access() i2c: i801: Centralize configuring block commands in i801_block_transaction i2c: i801: Centralize configuring non-block commands in i801_simple_transaction i2c: i801: Handle SMBAUXCTL_E32B in i801_block_transaction_by_block only i2c: i801: Add i801_simple_transaction(), complementing i801_block_transaction() Documentation: i2c: correct spelling dt-bindings: i2c: i2c-st: convert to DT schema i2c: i801: add helper i801_set_hstadd() i2c: i801: make FEATURE_BLOCK_PROC dependent on FEATURE_BLOCK_BUFFER i2c: i801: make FEATURE_HOST_NOTIFY dependent on FEATURE_IRQ i2c: i801: improve interrupt handler i2c: st: use pm_sleep_ptr to avoid ifdef CONFIG_PM_SLEEP ...
