mfd: madera: Add special errata reset handling for cs47l15

2020-11-19T08:34:22+00:00

An errata exists for cs47l15 where the reset must be handled differently and removed before DCVDD is applied. A soft reset is used for situations where a reset is required to reset state. This does however, make this part unsuitable for DCVDD supplies with a rise time greater than 2mS. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Add support for requesting the supply clocks

2019-11-11T08:45:03+00:00

Add the ability to get the clock for each clock input pin of the chip and enable MCLK2 since that is expected to be a permanently enabled 32kHz clock. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Fixup SPDX headers

2019-07-02T11:11:31+00:00

GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch to that. Remove some redundant copyright notices and correct some instances where the wrong comment type has been used in header files. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Add Madera core support for CS47L92

2019-07-02T11:11:31+00:00

This patch adds all the core support and defines for the Cirrus Logic CS42L92, CS47L92 and CS47L93 smart audio CODECs. Registers or fields are named MADERA_* if it is part of the common hardware platform and does not conflict with any other Madera codecs. It is named CS47L15_* if it is unique to CS47L15 and conflicts with definitions on other codecs.

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. Signed-off-by: Richard Fitzgerald Signed-off-by: Lee Jones

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. Signed-off-by: Richard Fitzgerald Signed-off-by: Lee Jones

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).
