mfd: madera: Add shared data for accessory detection

2019-01-03T08:32:42+00:00

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.

mfd: madera: Remove unused forward reference

2018-10-23T07:58:34+00:00

The madera_irqchip_pdata struct was replaced by the irq_flags
member of struct madera_pdata so the forward reference is
obsolete.

mfd: madera: Add irqchip data pointer into struct madera

2018-09-10T15:43:27+00:00

Put the pointer to struct regmap_irq_chip_data into the parent
mfd structure so that the child irqchip driver does not need
a trivial private structure to store only this pointer. As
the irqchip child driver already has a pointer to the parent
struct madera it can use that to store the pointer. This also
means that the irqchip driver does not need a double-indirection
from its local struct to get at the parent struct madera.

by the extcon driver.

mfd: madera: Add common support for Cirrus Logic Madera codecs

2018-06-05T10:14:56+00:00

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).

mfd: madera: Add register definitions for Cirrus Logic Madera codecs

2018-06-05T10:14:32+00:00

This patch adds a header file of register definitions for Cirrus
Logic "Madera" class codecs. These codecs are all based off a common
set of hardware IP so have a common register map (with a few minor
device-to-device variations).

The registers.h file is tool-generated directly from the hardware design
but has been manually stripped down to reduce size (full register
map is >44000 lines). All names are kept the same as datasheet names
so that they can be cross-referenced between source and datasheet without
confusion.

The register map layout is kept fully-defined rather than factored into
macros and/or block-indexing code. The major reasons for this are:

 - #1 is that it makes the source highly greppable, which is important.
   "What does the driver do with register bits XYZ" or "Where does it use
   register bits XYZ" are commonly types of questions. These can be quickly
   answered by a grep. Squashing definitions into generator macros or block-
   indexing code is a way of defeating grep.

 - most of the register definitions are used in tables, so a constant value
   is required. Using generator macros make the table definition clunky and
   obscure.

 - the code is clearer when it's there in the source exactly what register
   and field it is using

 - it is easier to diff the register map of a new (unsupported) codec against
   what is already supported and merge in differences

 - it makes the register map available in source for maintenance/debugging
   instead of having to refer back to the datasheet for a register map
