2023-10-13power: reset: gpio-poweroff: make sys handler priority configurableStefan Eichenberger1-2/+7
Add a priority property equal to gpio-restart to allow increasing the priority of the gpio-poweroff handler.

2023-10-13power: reset: gpio-poweroff: use sys-off handler APIStefan Eichenberger1-25/+12
Use the new sys-off handler API for gpio-poweroff. This allows us to have more than one poweroff handler and prioritise them.

Use a struct to store the module variables. This is required to later move to notifier_blocks where we can have several instances.

2023-07-19power: Explicitly include correct DT includesRob Herring1-1/+2
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.

2023-04-13power: reset: remove MODULE_LICENSE in non-modulesNick Alcock1-1/+0
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2018-12-05power: reset: gpio-poweroff: add ability to specific active and inactive delaysHeiko Stuebner1-2/+8
Similar to gpio-reset allow to specify active and inactive delays while keeping the 100ms defaults that were used previously all the time. The dt-properties are named the same as in gpio-reset but get an "-ms" suffix as properties should contain such a suffix specifying its unit.

2018-04-25gpio-poweroff: Use gpiod_set_value_cansleepMike Looijmans1-2/+2
The power-off call is done in a context that must be able to sleep, so use gpiod_set_value_cansleep instead of the atomic gpiod_set_value call. This fixes a kernel warning at shutdown when the gpio is controlled through an IO expander for example.

2014-07-18power: poweroff: gpio: convert to use descriptorsLinus Walleij1-33/+19
This switches the GPIO poweroff driver to use GPIO descriptors rather than numeral GPIOs. We get rid of the specific inversion handling as GPIO descriptors know if they are active low or high and can assert the line properly, so we do not need to check the flag OF_GPIO_ACTIVE_LOW returned from the old call of_get_gpio_flags() anymore. Also convert to use managed resources and use dev_* message printing while we're at it.

2013-01-03Drivers: power: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
