Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"I2C has one bugfix (qcom-geni driver), one arch enablement (i2c-omap
driver, no code change), and a new driver (nvidia-gpu) this time"
* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
usb: typec: ucsi: add support for Cypress CCGx
i2c: nvidia-gpu: make pm_ops static
i2c: add i2c bus driver for NVIDIA GPU
i2c: qcom-geni: Fix runtime PM mismatch with child devices
MAINTAINERS: Add entry for i2c-omap driver
i2c: omap: Enable for ARCH_K3
dt-bindings: i2c: omap: Add new compatible for AM654 SoCs
