mfd: madera: Simplify with spi_get_device_match_data()

2024-07-04T16:38:40+00:00

Use spi_get_device_match_data() helper to simplify a bit the driver. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Charles Keepax Link: https://lore.kernel.org/r/20240606142457.130553-2-krzysztof.kozlowski@linaro.org Signed-off-by: Lee Jones

mfd: Explicitly include correct DT includes

2023-08-18T20:48:03+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

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 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).
