ec00968f08 device: i2c: Add support for I2C bus operations
In order to support doing bus operations on an I2C device that is
described in the devicetree there needs to be some linkage of the
device and the existing opaque I2C controller bus number.

This is provided in a similar fashion to the existing SMBUS operations
but modified to fit within the existing I2C infrastructure.

Variants of the existing I2C helper functions are provided that will
obtain the bus number that corresponds to this device by looking for
the SOC-provided I2C bus operation structure to provide a function
that will make that translation.

For example an SOC using a PCI I2C controller at 0:15.0 could use:

soc/intel/.../i2c.c:
  static int i2c_dev_to_bus(struct device *dev)
  {
    if (dev->path.pci.devfn == PCI_DEVFN(0x15, 0))
      return 0;
    return -1;
  }
  static struct i2c_bus_operation i2c_bus_ops = {
    .dev_to_bus = &i2c_dev_to_bus
  }
  static struct device_operations i2c_dev_ops = {
    .ops_i2c_bus = &i2c_bus_ops
    ...
  }

With an I2C device on that bus at address 0x1a described in the tree:

devicetree.cb:
  device pci 15.0 on # I2C0
    chip drivers/i2c/sample
      device i2c 1a.0 on end
    end
  end

That driver can then do I2C transactions with the device object
without needing to know that the SOC-specific bus number that this
I2C device lives on is "0".

For example it could read a version value from register address 0
with a byte transaction:

drivers/i2c/sample/sample.c:
  static void i2c_sample_enable(struct device *dev)
  {
    uint8_t ver;
    if (!i2c_dev_readb(dev, 0x00, &ver))
      printk(BIOS_INFO, "I2C %s version 0x02x\n", dev_path(dev), ver);
  }

1010b4aeac acpi_device: Add support for writing ACPI I2C descriptors
Add required definitions to describe an ACPI I2C bus and a method to
write the I2cSerialBus() descriptor to the SSDT.

This will be used by device drivers to describe their I2C resources to
the OS.  The devicetree i2c device can supply the address and 7 or 10
bit mode as well as indicate the GPIO controller device, and the bus
speed can be fixed or configured by the driver.

chip.h:
  struct drivers_i2c_generic_config {
    enum i2c_speed bus_speed;
  };

generic.c:
  void acpi_fill_ssdt_generator(struct device *dev) {
    struct drivers_i2c_generic_config *config = dev->chip_info;
    struct acpi_i2c i2c = {
      .address = dev->path->i2c.device,
      .mode_10bit = dev->path.i2c.mode_10bit,
      .speed = config->bus_speed ? : I2C_SPEED_FAST,
      .resource = acpi_device_path(dev->bus->dev)
    };
    ...
    acpi_device_write_i2c(&i2c);
    ...
  }

devicetree.cb:
  device pci 15.0 on
    chip drivers/i2c/generic
      device i2c 10.0 on end
    end
  end

SSDT.dsl:
  I2cSerialBus (0x10, ControllerInitiated, 400000, AddressingMode7Bit,
                "\\_SB.PCI0.I2C0", 0, ResourceConsumer)

d9af3cecae device: Add an ACPI device name and path concept to devices
Add a function to "struct device_operations" to return the ACPI name
for the device, and helper functions to find this name (either from
the device or its parent) and to build a fully qualified ACPI path
from the root device.

This addition will allow device drivers to generate their ACPI AML in
the SSDT at boot, with customization supplied by devicetree.cb,
instead of needing custom DSDT ASL for every mainboard.

The root device acpi_name is defined as "\\_SB" and is used to start
the path when building a fully qualified name.

This requires SOC support to provide handlers for returning the ACPI
name for devices that it owns, and those names must match the objects
declared in the DSDT.  The handler can be done either in each device
driver or with a global handler for the entire SOC.

Simplified example of how this can be used for an i2c device declared
in devicetree.cb with:

  chip soc/intel/skylake          # "\_SB" (from root device)
    device domain 0 on            # "PCI0"
      device pci 19.2 on          # "I2C4"
        chip drivers/i2c/test0
          device i2c 1a.0 on end  # "TST0"
        end
      end
    end
  end

And basic SSDT generating code in the device driver:

  acpigen_write_scope(acpi_device_scope(dev));
  acpigen_write_device(acpi_device_name(dev));
  acpigen_write_string("_HID", "TEST0000");
  acpigen_write_byte("_UID", 0);
  acpigen_pop_len(); /* device */
  acpigen_pop_len(); /* scope */

Will produce this ACPI code:

  Scope (\_SB.PCI0.I2C4) {
    Device (TST0) {
      Name (_HID, "TEST0000")
      Name (_UID, 0)
    }
  }

4650f5baff sconfig: Add a new generic device type
Add support for a basic generic device in the devicetree to bind to a
device that does not have a specific bus, but may need to be described
in tables for the operating system.  For instance some chips may have
various GPIO connections that need described but do not fall under any
other device.

In order to support this export the basic 'scan_static_bus()' that can
be used in a device_operations->scan_bus() method to scan for the generic
devices.

It has been possible to get a semi-generic device by using a fake PNP
device, but that isn't really appropriate for many devices.

Also Re-generate the shipped files for sconfig.  Use flex 2.6.0 to avoid
everything being rewritten.  Clean up the local paths that leak into the
generated configs.

Use the second token for an i2c device entry in devicetree.cb to
indicate if it should use 10-bit addressing or 7-bit.  The default if
not provided is to use 7-bit addressing, but it can be changed to
10-bit addressing with the ".1" suffix.  For example:

chip drivers/i2c/generic
  device i2c 3a.1 on end

bd1fdc6e84 nb/intel/sandybridge/raminit: Add XMP support
Some vendors store lower frequency profiles in the regular SPD,
if the SPD contains a XMP profile. To make use of the board's and DIMM's
maximum supported DRAM frequency, try to parse the XMP profile and
use it instead.

Validate the XMP profile to make sure that the installed DIMM count
per channel is supported and the requested voltage is supported.

To reduce complexity only XMP Profile 1 is read.

Allows my DRAM to run at 800Mhz instead of 666Mhz as encoded in the
default SPD.

Test system:
 * Gigabyte GA-B75M-D3H
 * Intel Pentium CPU G2130

According to the PNP ISA v1.0a spec, config registers in the range of

Config register 0xff is reserved and is defined as such.

Currently, only vendor specific registers 0xf0, 0xf1, 0xf4, and 0xfa
are able to be set using the PNP_MSCx bit flag masks.

This patch adds support for all 15 vendor specific config registers,
and updates the existing superio pnp_info to use them where appropriate.

devices on the root bus and secondary buses. Booted Linux and checked
the configuration with `lspci -v`. Got the configuration through Muen's
tools which are very picky about overlapping and alignment. Booted a
Muen based system that uses many onboard devices. GMA, xHCI and one NIC
(on a secondary bus) were verified to function properly.
