Subject: [PULL REQUEST] i2c for 4.12
Linus,
I2C has the following updates for you:
* an immutable cross-subsystem branch fixing PMIC access on Intel Baytrail
* bigger driver updates to the designware, meson, exynos5 drivers
* new i2c_acpi_new_device() function to create devices from ACPI
* struct i2c_driver has now a flag 'disable_i2c_core_irq_mapping' to
allow custom IRQ mapping in case the default does not fit
* mux subsystem centralized error messages in its core
* new driver for ltc4306 i2c mux
* usual set of small updates
Please pull.
Thanks,
Wolfram
