Merge branch 'i2c/for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "I2C has: - using defines for bus speeds to avoid mistakes in hardcoded values; lots of small driver updates because of that. Thanks, Andy! - API change: i2c_setup_smbus_alert() was renamed to i2c_new_smbus_alert_device() and returns ERRPTR now. All in-tree users have been converted - in the core, a rare race condition when deleting the cdev has been fixed. Thanks, Kevin! - lots of driver updates. Thanks, everyone! I also want to mention: The amount of review and testing tags given was quite high this time. Thank you to these people, too. I hope we can keep it like this!" * 'i2c/for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (34 commits) i2c: rcar: clean up after refactoring i2c_timings macintosh: convert to i2c_new_scanned_device i2c: drivers: Use generic definitions for bus frequencies i2c: algo: Use generic definitions for bus frequencies i2c: stm32f7: switch to I²C generic property parsing i2c: rcar: Consolidate timings calls in rcar_i2c_clock_calculate() i2c: core: Allow override timing properties with 0 i2c: core: Provide generic definitions for bus frequencies i2c: mxs: Use dma_request_chan() instead dma_request_slave_channel() i2c: imx: remove duplicate print after platform_get_irq() i2c: designware: Fix spelling typos in the comments i2c: designware: Discard i2c_dw_read_comp_param() function i2c: designware: Detect the FIFO size in the common code i2c: dev: Fix the race between the release of i2c_dev and cdev i2c: qcom-geni: Drop of_platform.h include i2c: qcom-geni: Grow a dev pointer to simplify code i2c: qcom-geni: Let firmware specify irq trigger flags i2c: stm32f7: do not backup read-only PECR register i2c: smbus: remove outdated references to irq level triggers i2c: convert SMBus alert setup function to return an ERRPTR ...
