From e21ab17904ff5c56bd6d6d062824ca584a42d89f Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Tue, 27 Dec 2016 14:00:54 +0000 Subject: [PATCH] ASoC: dwc: Enable 24 bit sample size in PIO mode Sample size of 24 bits use in reality 32 bits for storage. We can safelly enable this sample size and treat the data as 32 bits. Tested in a x86_64 platform and in ARC AXS101 SDP platform.
