leds: pwm: Support ACPI via firmware-node framework
DT specific handling is replaced by firmware-node abstration to support
ACPI specification of PWM LEDS.
Example ASL:
Device (PWML)
{
Name (_HID, "PRP0001")
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package () { Package () {"compatible",
Package () {"pwm-leds"}}}})
Device (PWL0)
{
Name (_HID, "PRP0001")
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package () {
Package () {"label", "alarm-led"},
Package () {"pwms", Package ()
{\_SB_.PCI0.PWM, 0, 600000, 0}},
Package () {"linux,default-state", "off"}}})
}
}
