From 07b7acb51d283d8469696c906b91f1882696a4d4 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 7 Jun 2017 00:20:01 +0000 Subject: ASoC: rsnd: update pointer more accurate Current rsnd driver updates pointer when DMA transfer was finished in DMA transfer mode. But PulseAudio requests more accurate pointer update when timer mode. This patch consider about DMA transfer residue and update more accurate pointer.
