Merge branch 'i2c/for-mergewindow' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "Mostly driver updates and refactorization. The removal of the XLR driver and the i801 refactoring stand out a little. In the core, we enabled async suspend/resume for I2C controllers and their clients. No issues were reported during the test phase in -next. We will see how this goes for mainline" * 'i2c/for-mergewindow' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (54 commits) i2c: sh_mobile: remove unneeded semicolon i2c: riic: Use platform_get_irq() to get the interrupt i2c: sh_mobile: Use platform_get_irq_optional() to get the interrupt i2c: bcm2835: Use platform_get_irq() to get the interrupt i2c: aspeed: Remove unused includes dt-bindings: i2c: aspeed: Drop stray '#interrupt-cells' i2c: sh_mobile: update to new DMAENGINE API when terminating i2c: rcar: update to new DMAENGINE API when terminating i2c: exynos5: Fix getting the optional clock i2c: designware-pci: Convert to use dev_err_probe() i2c: designware-pci: use __maybe_unused for PM functions i2c: designware-pci: Group MODULE_*() macros i2c: designware-pci: Add a note about struct dw_scl_sda_cfg usage i2c: designware-pci: Fix to change data types of hcnt and lcnt parameters i2c: designware: Do not complete i2c read without RX_FULL interrupt eeprom: at24: Add support for 24c1025 EEPROM dt-bindings: at24: add at24c1025 i2c: tegra: use i2c_timings for bus clock freq dt-bindings: at24: Rework special case compatible handling i2c: i801: Don't clear status flags twice in interrupt mode ...
