pinctrl: sprd-sc9860: Convert to platform remove callback returning void

2023-10-10T13:47:50+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(). To convert the sprd-sc9860 driver, make sprd_pinctrl_remove() return void (instead of zero) and use .remove_new as callback.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24+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.

pinctrl: sprd: Add missing header(s)

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. Signed-off-by: Andy Shevchenko Reviewed-by: Baolin Wang

For Spreadtrum pin controller, it will be the high impedance mode if disable input and output mode for a pin. Thus add PIN_CONFIG_BIAS_HIGH_IMPEDANCE configuration to support it.

pinctrl: sprd: Use the correct pin output configuration

2020-03-27T21:07:10+00:00

The Spreadtrum pin controller did not supply registers to set high level or low level for output mode, instead we should let the pin controller current configuration drive values on the line. So we should use the PIN_CONFIG_OUTPUT_ENABLE configuration to enable or disable the output mode.
