From: Hou Zhiqiang <[email protected]>
Add an new IRQ chip declaration for LS1043A and LS1088A
- compatible "fsl,ls1043a-extirq" for LS1043A, LS1046A. SCFG_INTPCR[31:0]
of these SoCs is stored/read as SCFG_INTPCR[0:31] defaultly(bit
reverse)
- compatible "fsl,ls1088a-extirq" for LS1088A, LS208xA, LX216xA
