[PATCH v5 5/8] ASoC: sun4i-i2s: Add regmap field to set DAI format codekipper@gmail.com - 2017-08-19 14:50 +0200

| Message-ID | <ugbmp-1m2-9@gated-at.bofh.it> |
From: Marcus Cooper <codekipper@gmail.com>
On the newer SoCs the bits to configure the operational mode are
located in a different register. Add a regmap field so that this
location can be configured.
