From bd517707d85f19a7339ea8b882fcbf0fd9976bd6 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Wed, 17 Jul 2019 12:56:34 +0200 Subject: ASoC: fsl_sai: derive TX FIFO watermark from FIFO depth The DMA request schould be triggered as soon as the FIFO has space for another burst. As different versions of the SAI block have different FIFO sizes, the watrmark level needs to be derived from version specific data.
