Subject: [PATCH v2 01/10] ASoC: sun4i-i2s: Increase DMA max burst to 8
Date: Tue, 17 Jan 2017 15:02:21 +0100	[thread overview]
Message-ID: <20170117140230.23142-2-mylene.josserand@free-electrons.com> (raw)
In-Reply-To: <20170117140230.23142-1-mylene.josserand@free-electrons.com>

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.

For more details, see commit from Chen-Yu Tsai:
commit 730e2dd0cbc7 ("ASoC: sun4i-codec: Increase DMA max burst to 8")
