pinctrl: lochnagar: Don't build on MIPS

2023-11-16T13:40:38+00:00

MIPS appears to define a RST symbol at a high level, which clashes
with some register naming in the driver. Since there is currently
no case for running this driver on MIPS devices simply cut off the
build of this driver on MIPS.

pinctrl: cirrus: drop the wrapper around pinctrl_gpio_direction_input()

2023-11-04T09:23:23+00:00

pinctrl_gpio_direction_input() now has the same signature as the
wrapper around it so we can drop them.

treewide: rename pinctrl_gpio_direction_output_new()

2023-11-04T09:23:22+00:00

Now that pinctrl_gpio_direction_output() is no longer used, let's drop
the '_new' suffix from its improved variant.

pinctrl: cirrus: use new pinctrl GPIO helpers

2023-11-04T09:23:20+00:00

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

pinctrl: cirrus: madera-core: Convert to platform remove callback returning void

2023-10-10T13:37:19+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

pinctrl: cs42l43: Add support for the cs42l43

2023-08-17T11:06:11+00:00

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface
(Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed
for portable applications. It provides a high dynamic range, stereo
DAC for headphone output, two integrated Class D amplifiers for
loudspeakers, and two ADCs for wired headset microphone input or
stereo line input. PDM inputs are provided for digital microphones.

Add a basic pinctrl driver which supports driver strength for the
various pins, gpios, and pinmux for the 2 multi-function pins.

pinctrl: lochnagar: Add missing header(s)

2022-10-24T14:06:46+00:00

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

pinctrl: Propagate firmware node from a parent device

2021-12-22T02:09:56+00:00

When creating MFD platform devices the firmware node is left unset.
This, in particular, prevents GPIO library to use it for different
purposes. Propagate firmware node from the parent device and let
GPIO library do the right thing.

While at it, slightly modify the headers to reflect the usage of APIs.
