[alsa-devel] [PATCH 09/13] ASoc: rsnd: dma: Calculate PDMACHCRE with consider of BUSIF

[Kuninori Morimoto]

From: Jiada Wang <jiada_wang at mentor.com>

PDMACHCR setting for SSI only considers BUSIF0 so far.
But BUSIF1 ~ BUSIF7 also maybe used, in the future.

This patch updates table gen2_id_table_ssiu, to also consider
BUSIF number used by SSI.
