Merge branch 'i2c/for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "I2C has mostly driver updates this time. The few noteworthy changes are: the core has now support for analog and digital filters with at91 being the first user, a core addition to replace the NULL returning i2c_new_probed_device() with an ERR_PTR variant, and the pxa driver has finally being moved to use the generic I2C slave interface. We have quite a significant number of reviews per patch this time, so thank you to all involved!" * 'i2c/for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (37 commits) video: fbdev: matrox: convert to i2c_new_scanned_device i2c: icy: convert to i2c_new_scanned_device i2c: replace i2c_new_probed_device with an ERR_PTR variant i2c: Fix Kconfig indentation i2c: smbus: Don't filter out duplicate alerts i2c: i801: Correct Intel Jasper Lake SOC naming i2c: i2c-stm32f7: fix 10-bits check in slave free id search loop i2c: iproc: Add i2c repeated start capability i2c: remove helpers for ref-counting clients i2c: tegra: Use dma_request_chan() directly for channel request i2c: sh_mobile: Use dma_request_chan() directly for channel request i2c: qup: Use dma_request_chan() directly for channel request i2c: at91: Use dma_request_chan() directly for channel request i2c: rcar: Remove superfluous call to clk_get_rate() i2c: pxa: remove unused i2c-slave APIs i2c: pxa: migrate to new i2c_slave APIs i2c: cros-ec-tunnel: Make the device acpi compatible i2c: stm32f7: report dma error during probe i2c: icy: no need to populate address for scanned device i2c: xiic: Fix kerneldoc warnings ...
