From d0077aaf2206f3c3524d71a9f38b408dca63852f Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 12 Jan 2015 10:27:18 +0100 Subject: ASoC: fsl: Update set_tdm_slot() semantics The fsl-ssi and imx-ssi drivers use inverted semantics for the tx_mask and rx_mask parameter of the set_tdm_slot() callback compared to rest of ASoC. This patch updates the driver's semantics to be consistent with the rest of ASoC, i.e. a set bit means a active slot and a cleared bit means a inactive slot. This will allow us to use the set_tdm_slot() API in a more generic way.
