i2c_init() leaves the I2C device enabled. Combined with the default
interrupt mask (0x8ff) and the fact that the interrupt line is shared,
this leads to an interrupt storm in the OS until a proper I2C driver
is loaded.
This change clears the interrupt mask to prevent the interrupt storm.

The Maxim Integrated 98357A codec is an I2S slave device that has no
control channel for configuration and instead provides a GPIO that is
used for channel selection and power down. This means it does not fit
into a bus hierarchy easily and is instead represented as a generic
device and found with a static bus scan using the devicetree.
This driver provides configuration options for passing the "sdmode" GPIO
descriptor as well as a second option for "sdmode delay" which can
configure the timing of the sdmode toggling in relation to the I2S
channel output.
In addition an GPIO can be provided to indicate to the driver whether
this device is present or not. This can be used for board designs that
may have different codec possibilities that are selected by HW strap.
Sample usage for this device driver:
device pci 1f.3 on
chip drivers/generic/max98357a
register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C6)"
register "sdmode_delay" = "100"
device generic 0 on end
end
end
Will result in the following code in the SSDT:
Scope (\_SB.PCI0.HDAS) {
Device (MAXM) {
Name (_HID, "MX98357A")
Name (_UID, Zero)
Name (_DDN, "Maxim Integrated 98357A Amplifier")

This adds a generic I2C driver that can be described in the devicetree
and used to generate ACPI objects in the SSDT based on the information
provided in the config registers.
The I2C bus can be configured and the device can provide an interrupt and
wake capability to the OS. A configuration option allows for a GPIO to
be provided that will be checked to determine if the device is preset on
the board before including it in the generated SSDT.
The driver is generic enough to be used for basic I2C devices that do
not have special configuration needs such as touchpads, touchscreens,
sensors, some audio codec/amplifiers, etc.
Sample usage for a touchpad device:
device pci 15.1 on
chip drivers/i2c/generic
register "hid" = ""ELAN0000""
register "desc" = "ELAN Touchpad"
register "irq" = "IRQ_EDGE_LOW(GPP_B3_IRQ)"

Intel WiFi devices that support wake-on-wifi need to declare a Power
Resource for this wake pin. Typically this has been done with a
static declaration in the DSDT for each mainboard. By adding it to
the existing intel/wifi driver it can be done based on a
configuration register in the devicetree.
Additionally the WiFi regulatory domain can be set in the SSDT
directly instead of needing to use NVS to pass the value to the DSDT.
Also add device IDs for Wilkins Peak 2 and Stone Peak 2 devices that
are found on Chromebooks, and clean up a long line and some comment
formatting.
This was tested by booting on an HP Chromebook 13 device and comparing
that the output in the SSDT matches what used to be in the DSDT. The
WRDD value is read from VPD, if present, not from devicetree.cb.
Additionally the case where CONFIG_DRIVERS_INTEL_WIFI is enabled but
the wifi device is not described in devicetree.cb is tested to ensure
it still generates the AML but does not include the _PRW wake pin.
Example:
devicetree.cb:
device pci 1c.0 on
chip drivers/intel/wifi
register "wake" = "GPE0_DW0_16"
device pci 00.0 on end
end
end

One thing that is vital to this patch is the MAC address setting
in case the EEPROM/efuse is unconfigured.
Linux now recognises the default MAC address on GA-G41M-ES2L which
does rely on the default bios settings for the MAC address.

The values were obtained from vendor bios at runtime.
I am not 100% sure of the sequence required to initiate them,
but guessed from the gm45 code. There may be some status bytes
needed to be polled during the sequence that is missing,
but as I don't have bios writer's datasheet it's very hard
for me to know.

Previously, due to a bug in devicetree and incorrect IRQ
settings in ACPI, SATA controller would not initialize
any HDDs in the OS, even though it worked in SeaBIOS.
The devicetree setting is not needed because SATA must
function in "plain" mode on this board, as "combined" mode
does not work at all.

Add a PCI driver for the skylake SD card device and have it generate
an entry in the SSDT for the card detect GPIO if it is provided by the
mainboard in devicetree.
This sets up a card detect GPIO configuration that will trigger an
interrupt on both edges with a 100ms debounce timeout and can wake the
SD controller from D3 state.
The GpioInt() entry is bound to the "cd-gpio" device property which will
be consumed by the kernel driver.
The resulting ACPI output in the SSDT will be combined with the SDXC
device declaration in the DSDT.
Example:
Scope (\_SB.PCI0.SDXC)
{
Name (_CRS, ResourceTemplate () {
GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000,
"\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 }
})
Name (_DSD, Package () {
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package () {
Package () { "cd-gpio", Package () { \_SB.PCI0.SDXC, 0, 0, 1 } }
}
})
}

Add the Audio DSP device for skylake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.
This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.
