I have some question about ACPI table. I want to control Intel Edison default GPIO on boot, so I make ACPI table to control it. But did not cause any changes. This is my ASL code:
Device (DEV)
    Name (_HID, "PRP0001")
    Name (_DDN, "GPIO LEDs device")
    Name (_CRS, ResourceTemplate()
            GpioIo (Shared, PullNone, 0x0000, 0x0000,
                    IoRestrictionOutputOnly, "\\_SB.PCI0.GPI0",
                    0x00, ResourceConsumer,,){12,13}
    Name (_DSD, Package () {
        ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
        Package () {
            Package () { "compatible", Package() { "gpio-leds" } },
        ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
        Package () {
            Package () {"led-0", "LED0"},
            Package () {"led-1", "LED1"},
     * For more information about these bindings see:
     * Documentation/devicetree/bindings/leds/common.yaml,
     * Documentation/devicetree/bindings/leds/leds-gpio.yaml and

     Name (LED0, Package () {
            ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
            Package () {
                Package () {"label", "green"},
                Package () {"default-state", "off"},
                Package () {"gpios", Package () {^LEDS, 0, 0, 0}},
                Package () {"retain-state-suspended", 1},
     Name (LED1, Package () {
            ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
            Package () {
                Package () {"label", "red"},
                Package () {"default-state", "off"},
                Package () {"gpios", Package () {^LEDS, 0, 1, 0}},
                Package () {"retain-state-suspended", 1},
Look like my leds_test.aml is loaded.
This is my /sys/kernel/debug/gpio:

But I have not got my LED on,and also I ensure CONFIG_LEDS_GPIO=y and CONFIG_LEDS_CLASS=y in my kernel configuration and built kernel.
                First of all, you have ambiguous GPIO resources in _CRS. What did you mean under pin 47 is being provided as GpioIo() and GpioInt() simultaneously? Second, it's not obvious what did you mean under I want to ... GPIO 48 to low when you are talking about GpioInt(). Please, clarify these items in the question.

                Sorry is my fault ,I thought Gpioint() means initial.... I changed my ASL code.then I means want to set GPIO 47 value to high and GPIO 48 value to low in boot

                In new kernels the GPIO numbering is kept the same for backward compatibility, so GP47 means GPIO 47 in the kernel and ACPI. You may do this from ACPI, but you need to understand that the actual pin value comes from the driver. So before the driver is loaded nothing is changed, even if you have ACPI tables already present and parsed.

                I suggest to drop unrelated / staled comments. Meanwhile I think you need to check polarity of the pin. In my case I used Active Low and had to update _DSD gpios property for that. In any case the example in answer is correct and works for me.

Follow this leds.asli and try to create test example that is work now.
example:

    Name (_DDN, "GPIO LEDs device")
    Name (_CRS, ResourceTemplate()

                I have taken this example + DefinitionBlock() and Scope(), changed GPIO to 48 and set it active low (because it's DFRobot IO expander board). Then I ensure CONFIG_LEDS_GPIO=y and CONFIG_LEDS_CLASS=y in my kernel configuration and built kernel.  I compiled ASL and attached it to initramfs and booted. As soon as LED GPIO driver is probed (see below), I have got my LED on. grep led /sys/kernel/debug/gpio: gpio-48..., [    0.001269] ACPI: SSDT ACPI table found in initrd [led48.aml], [   22.627591] bus: 'platform': really_probe: bound device PRP0001:00 to driver leds-gpio.

                So, @22.62 seconds from boot I have got my LED on. It took long due to big initramfs to decompress.
