2023-10-02gpio: mpc5200: Convert to platform remove callback returning voidUwe Kleine-König1-5/+3
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.

2023-07-19gpio: Explicitly include correct DT includesRob Herring1-1/+1
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.

2023-03-06gpiolib: split of_mm_gpio_chip out of linux/of_gpio.hArnd Bergmann1-1/+1
This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.

2016-02-16gpio: Include linux/gpio.h instead of asm/gpio.hBjorn Helgaas1-1/+0
Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary. This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise bolierplate asm/gpio.h").
