Subject[PATCH v4 0/3] Enable ACPI-defined peripherals on i2c-piix4 SMBus
Date
These patches fix a couple of issues with the i2c-piix4 driver on
AMD Family 16h Model 30h SoCs and add ACPI-based enumeration to the
i2c-piix4 driver.

Some I2C peripherals, eg. PCA953x IO expander, are not discovered by the
probe or detect mechanisms when attached to an SMBus controller that uses
the i2c-piix4 SMBus driver.

ACPI provides a mechanism to define these peripherals and the controller
port that they're attached to.

Changes:
v4:
remove unnecessary SB800_MAIN_PORTS constant
reduce piix4_remove change
v3:
take chip revision into account when determining port selection register
v2:
count the adapters, instead of misusing port numbers

Andrew Cooks (3):
i2c: piix4: Fix port selection for AMD Family 16h Model 30h
i2c: piix4: fix probing of reserved ports on AMD
i2c: piix4: add ACPI support
