Subject: [PATCH v5 14/17] ASoC: madera: Add common support for Cirrus Logic Madera codecs
The Cirrus Logic Madera codecs are a family of related codecs with
extensive digital and analogue I/O, digital mixing and routing,
signal processing and programmable DSPs.
This patch adds common support code shared by all Madera codecs.
