From ebad64d19377957976963f99ce1fcf2f09796357 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Myl=C3=A8ne=20Josserand?= Date: Tue, 17 Jan 2017 15:02:21 +0100 Subject: [PATCH] ASoC: sun4i-i2s: Increase DMA max burst to 8 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit As done previously for sun4i-codec, the DMA maxburst of 4 is not supported by every SoCs so the DMA controller engine returns "unsupported value". As a maxburst of 8 is supported by all variants, this patch increases it to 8.
