In that case you should name the block gpc-imx7d rather than gpcv2 and symbol as GPC_IMX7D rather than IMX_GPCV2.

You didn't get my point. Rather than defining it as a global variable, we should try to keep imx_gpcv2_irq as an internal data structure to irqchip driver, and use well-defined interface to access the data from pm driver when necessary.
