Merge branch 'i2c/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: - bus recovery can now be given a pinctrl handle and the I2C core will do all the steps to switch to/from GPIO which can save quite some boilerplate code from drivers - "fallthrough" conversion - driver updates, mostly ID additions * 'i2c/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (32 commits) i2c: iproc: fix race between client unreg and isr i2c: eg20t: use generic power management i2c: eg20t: Drop PCI wakeup calls from .suspend/.resume i2c: mediatek: Fix i2c_spec_values description i2c: mediatek: Add i2c compatible for MediaTek MT8192 dt-bindings: i2c: update bindings for MT8192 SoC i2c: mediatek: Add access to more than 8GB dram in i2c driver i2c: mediatek: Add apdma sync in i2c driver i2c: i801: Add support for Intel Tiger Lake PCH-H i2c: i801: Add support for Intel Emmitsburg PCH i2c: bcm2835: Replace HTTP links with HTTPS ones Documentation: i2c: dev: 'block process call' is supported i2c: at91: Move to generic GPIO bus recovery i2c: core: treat EPROBE_DEFER when acquiring SCL/SDA GPIOs i2c: core: add generic I2C GPIO recovery dt-bindings: i2c: add generic properties for GPIO bus recovery i2c: rcar: avoid race when unregistering slave i2c: tegra: Avoid tegra_i2c_init_dma() for Tegra210 vi i2c i2c: tegra: Fix runtime resume to re-init VI I2C i2c: tegra: Fix the error path in tegra_i2c_runtime_resume ...
