Subject: [PATCH v3 0/3] Enable ACPI-defined peripherals on i2c-piix4 SMBus
Date: Mon, 29 Jan 2018 13:54:17 +1000	[thread overview]
Message-ID: <cover.1513215039.git.andrew.cooks@opengear.com> (raw)

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:
v3:
  take chip revision into account when determining port selection register
v2:
  count the adapters, instead of misusing port numbers

  i2c: piix4: fix number of SMBus ports on HUDSON2
  i2c: add ACPI support for i2c-piix4
