4*4882a593SmuzhiyunThe Pixel Pipeline (PXP) is a memory-to-memory graphics processing engine
5*4882a593Smuzhiyunthat supports scaling, colorspace conversion, alpha blending, rotation, and
6*4882a593Smuzhiyunpixel conversion via lookup table. Different versions are present on various
7*4882a593Smuzhiyuni.MX SoCs from i.MX23 to i.MX7.
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunRequired properties:
10*4882a593Smuzhiyun- compatible: should be "fsl,<soc>-pxp", where SoC can be one of imx23, imx28,
11*4882a593Smuzhiyun  imx6dl, imx6sl, imx6sll, imx6ul, imx6sx, imx6ull, or imx7d.
12*4882a593Smuzhiyun- reg: the register base and size for the device registers
13*4882a593Smuzhiyun- interrupts: the PXP interrupt, two interrupts for imx6ull and imx7d.
14*4882a593Smuzhiyun- clock-names: should be "axi"
15*4882a593Smuzhiyun- clocks: the PXP AXI clock

22*4882a593Smuzhiyun	interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
23*4882a593Smuzhiyun		     <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
24*4882a593Smuzhiyun	clock-names = "axi";
