[alsa-devel] [PATCH] ASoC: rsnd: dma: fix SSI9 4/5/6/7 busif dma address

[Kuninori Morimoto]

Hi Jiada

Thank you for your patch

> Currently each SSI unit 's busif dma address is calculated by
> following calculation formulation:
> 0xec540000 + 0x1000 * id + busif / 4 * 0xA000 + busif % 4 * 0x400
> 
> But according to user manual 41.1.4 Register Configuration
> ssi9 4/5/6/7 busif data register address
> (SSI9_4_BUSIF/SSI9_5_BUSIF/SSI9_6_BUSIF/SSI9_7_BUSIF)
> are out of this rule.
> 
> This patch updates the calculation formulation to correct
> ssi9 4/5/6/7 busif data register address
> 
> Fixes: commit 5e45a6fab3b9 ("ASoc: rsnd: dma: Calculate dma address with consider of BUSIF")

We don't need below anymore by this patch ?

	--- dma.c ----
	/*
	 * FIXME
	 *
	 * We can't support SSI9-4/5/6/7, because its address is
	 * out of calculation rule
	 */
	if ((id == 9) && (busif >= 4))
		dev_err(dev, "This driver doesn't support SSI%d-%d, so far",
			id, busif);
