From 8f29bb83586ea993e98b258e1fdb657367dd3c25 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Tue, 23 Mar 2021 13:07:01 +0800 Subject: soundwire: generic_allocation: fix confusion between group and packing The existing code makes no sense, we multiply a channel number by zero (SDW_BLK_GRP_CNT_1), and the result is used to configure the block packing mode. Sampling grouping and channel packing are two separate concepts in SoundWire. In addition, the bandwidth allocation allocates a vertical slice for each stream, which makes the use of the PER_CHANNEL packing mode irrelevant. Let's use the proper definition for block packing mode (PER_PORT). This change has no functional impact though since the net result is the same configuration of the DPN_BlockCtrl3 register, when implemented.
