Richard Fitzgerald	7f9472134a	mfd: madera: Add shared data for accessory detection ... Add variables to struct madera that will be shared by the extcon and audio codec drivers to synchronize output state during accessory detection. Also add a mutex to protect the DAPM pointer.

Richard Fitzgerald	b04e68d166	mfd: madera: Don't use regmap_read_poll_timeout to poll for BOOT_DONE ... While polling for BOOT_DONE the chip could NAK a read because it is still booting, which would terminate the regmap_read_poll_timeout() with an error. Instead implement a polling loop that ignores read errors so we always poll until the chip signals boot or the loop times out.

Richard Fitzgerald	16b27467f4	mfd: madera: Add common support for Cirrus Logic Madera codecs ... This adds the generic core support for Cirrus Logic "Madera" class codecs. These are complex audio codec SoCs with a variety of digital and analogue I/O, onboard audio processing and DSPs, and other features. These codecs are all based off a common set of hardware IP so can be supported by a core of common code (with a few minor device-to-device variations).
