[alsa-devel] [PATCH v2 3/6] ASoC: madera: Add common support for Cirrus Logic Madera codecs

From: Richard Fitzgerald rf@opensource.cirrus.com

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.

This patch also adds the pdata to the parent mfd pdata struct. Since there is a circular build dependency it's convenient to patch them both atomically.

Changes since v1: - Improve error message in madera_spin_sysclk - Handle spurious over temperature events - Factor out generic OF helper function for array reads - Rename destory functions to free - Add spaces in madera_dfc_width_text

Thanks, Charles
