Provide ACPI devices with devicetree-compatible annotations for the
three leds and the button of the APU1, as well as the GPIO driver.
This will cause the Linux kernel to automatically load the following
modules:
leds_gpio (CONFIG_LEDS_GPIO)
gpio_keys_polled (CONFIG_KEYBOARD_GPIO_POLLED)
gpio_sb8xx (CONFIG_GPIO_SB8XX)
See
http://events.linuxfoundation.org/sites/events/files/slides/ACPI_vs_DT.pdf
and https://lwn.net/Articles/612062/ for some more information on how
the PRP0001 HID works.
To make this usable a Linux GPIO driver for the AMD chipset is also
required, which I am currently working on, but have not submitted
upstream yet.
Leds have been named after the convention in
Documentation/leds/leds-class.txt:
LED Device Naming
=================
Is currently of the form:
"devicename:colour:function"
For comparison, on an OpenWRT device:
GPIOs 0-21, ath79:
gpio-1 (tp-link:green:usb ) out hi
gpio-2 (tp-link:green:system) out lo
gpio-3 (reset ) in hi
gpio-5 (tp-link:green:qss ) out lo
gpio-7 (qss ) in hi
gpio-9 (tp-link:green:wlan ) out lo
gpio-18 (rtl8366rb ) in hi
gpio-19 (rtl8366rb ) in hi
On the apu1:
GPIOs 288-511, platform/PRP0001:00, AMD SB8XX/SB9XX/A5X/A8X GPIO driver:
gpio-475 (switch1 ) in hi
gpio-477 (apu1:green:led1 ) out hi
gpio-478 (apu1:green:led2 ) out hi
gpio-479 (apu1:green:led3 ) out hi

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.
