How about doing like this:


/* LPAIF RXTX IRQ */
#define LPAIF_RXTX_IRQ_REG_ADDR(v, addr, port) \
		(v->rxtx_irq_reg_base + (addr) + v->rxtx_irq_reg_stride * (port))

#define LPAIF_RXTX_IRQEN_REG(v, port, dai_id) LPAIF_RXTX_IRQ_REG_ADDR(v, 
0x0, port)
#define LPAIF_RXTX_IRQSTAT_REG(v, port, dai_id) 
LPAIF_RXTX_IRQ_REG_ADDR(v, 0x4, port)
#define LPAIF_RXTX_IRQCLEAR_REG(v, port, dai_id) 
LPAIF_RXTX_IRQ_REG_ADDR(v, 0xC, port)

/* LPAIF VA IRQ */
#define LPAIF_VA_IRQ_REG_ADDR(v, addr, port) \
		(v->va_irq_reg_base + (addr) + v->va_irq_reg_stride * (port))

#define LPAIF_VA_IRQEN_REG(v, port, dai_id) LPAIF_VA_IRQ_REG_ADDR(v, 
0x0, port)
#define LPAIF_VA_IRQSTAT_REG(v, port, dai_id) LPAIF_VA_IRQ_REG_ADDR(v, 
0x4, port)
#define LPAIF_VA_IRQCLEAR_REG(v, port, dai_id) LPAIF_VA_IRQ_REG_ADDR(v, 
0xC, port)

How about:

#define LPAIF_DMACTL_REG(v, chan, dir, dai_id)  \
	is_cdc_dma_port(dai_id) ? \
	__LPAIF_CDC_DMA_REG(v, chan, dir, CTL, dai_id) : \
	__LPAIF_DMA_REG(v, chan, dir, CTL, dai_id)


simillar comments to most of the macros in this patch that are directly 
comparing the dai_ids.

Can we split this to LPAIF_CDC_TXRX_WRDMA_REG_ADDR and
LPAIF_CDC_VA_WRDMA_REG_ADDR macros?
