Didn't know what to do about the interrupt sources listed in the original txt file,
so I've split them off into a separate file. Hope that's okay.

-RDA Micro RDA8810PL Interrupt Controller
-
-The interrupt controller in RDA8810PL SoC is a custom interrupt controller
-which supports up to 32 interrupts.
-
-Required properties:
-
-- compatible: Should be "rda,8810pl-intc".
-- reg: Specifies base physical address of the registers set.
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
-  interrupt source. The value shall be 2.
-
-The interrupt sources are as follows:
-
-ID	Name

-0:	PULSE_DUMMY
-1:	I2C
-2:	NAND_NFSC
-3:	SDMMC1
-4:	SDMMC2
-5:	SDMMC3
-6:	SPI1
-7:	SPI2
-8:	SPI3
-9:	UART1
