Subject: [PATCH v6 7/7] ASoC: sun4i-i2s: Add support for H6 I2S
Date: Wed, 16 Oct 2019 09:07:40 +0200 [thread overview]
Message-ID: <20191016070740.121435-8-codekipper@gmail.com> (raw)
In-Reply-To: <20191016070740.121435-1-codekipper@gmail.com>
From: Jernej Skrabec <jernej.skrabec@siol.net>
H6 I2S is very similar to that in H3, except it supports up to 16
channels.
