2014-05-15rambi: Add ACPI devices and interrupts for codec and ALSDuncan Laurie
The Codec and ALS both have interrupt sources that can be configured. The ALS kernel driver currently does not try to use it but the codec driver does for things like jack detect. ACPI Devices are added, but as with other ACPI devices the HID may need to be updated once more official strings are decided.

2014-05-15rambi: Add ACPI table support for I2C devicesDuncan Laurie
In order to support probing I2C devices when the controller is in ACPI mode the mainboard needs to decalre them in the proper scope with the address/interrupt information. The touchpad devices are ATML0000/ELAN0000 and the touchscreen is ATML0001 so they can be distinguished in userland scripts based on ID. There is also a special "ISTP" node that indicates whether the devices is a touchpad (=1) or touchscreen (=0) in case this is useful to drivers. These names may not be final but they are a starting point and can be easily changed. Atmel devices also have a bootloader mode which needs to be declared as a separate device. Unfortunately it does not work as expected to have multiple I2cSerialBus() resources declared in a single device and have it select properly, even with the use of StartDependentFn(), so bootloader devices are declared separately. The original devices are left in \_SB scope and are only enabled if the I2C controllers are in PCI mode. The new devices are only enabled if the I2C controllers are in ACPI mode. BUG=chrome-os-partner:24380 BRANCH=baytrail TEST=manual 1) Ensure there is no change in functionality by default and that the devices are still probed by chromeos_laptop in the kernel. 2) Enable lpss_acpi_mode=1 in devicetree.cb and kernel changes to add _HID entries for devices in appropriate drivers. Ensure that the devices are probed successfully. Further changes are needed to the chromeos-touch-firmware scripts to load config and update firmware based on the new ACPI _HID entries. 3) Put touchpad in bootloader mode (by flashing bad firmware) and ensure that it is detected at address 0x25 and the firmware is able to be updated.

2014-05-07rambi: Add DIRQs for trackpad and touchscreenShawn Nematbakhsh
Also add the relevant info about these pins to the ASL tables + add SMBIOS type 41 data for these parts. BUG=chrome-os-partner:22863 TEST=Manual on Rambi. Set some pins to GPIO_DIRQ, and then verify DIRQ regwrites w/ GPIO_DEBUG look correct.

2014-05-05baytrail: interrupt routing supportAaron Durbin
This provides the initial support for interrupt routing in bay trail. It includes both acpi changes and board changes to ensure the interdependencies are met with the current ASL code. The PIRQ routing is handled by the mainboard exporting an irqroute.h header that describes the per device and PIRQ PCI settings. There are still a lot of ACPI errors in the kernel with this change, though. BUG=chrome-os-partner:23505 BRANCH=None TEST=Built and booted rambi into kernel.
