Subject: ASoC: imx: set watermarks for mx2-dma
From: Wolfram Sang <[email protected]>
commit 2c4cf17a52f04fbe929977252d5b8ab81d2c6e9b upstream.
They got accidently removed by f0fba2a (ASoC: multi-component - ASoC
Multi-Component Support). Reintroduce them and get rid of the
superfluous defines because the fiq-driver has its own hardcoded values.
