	There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.

2016-05-31	skylake: Add SD card device to configure card detect GPIO	Duncan Laurie
	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 } } } }) } Change-Id: Ie4c1bfadd962cf55a987edb9ef86e92174205770 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14995 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
