power: reset: syscon-poweroff: Use devm_register_sys_off_handler(POWER_OFF)

2024-02-13T01:17:26+00:00

Use device life-cycle managed register function to simplify probe and exit paths. This also makes our data struct per-device and not global, which allows for more than one instance of this device.

power: reset: syscon-poweroff: Move device data into a struct

2024-02-13T01:17:26+00:00

Currently all these device data elements are top level global variables. Move these into a struct. This will be used in the next patch when the global variable usage is removed. Doing this in two steps makes the patches easier to read.

power: reset: syscon-poweroff: Convert to platform remove callback returning void

2023-11-15T22:15:39+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.

power: reset: syscon-poweroff: get regmap from parent node

2023-09-12T19:07:14+00:00

Just like syscon-reboot device, the syscon-poweroff is supposed to be a child of syscon node, thus we can take the same approach as syscon-poweroff: deprecate the 'regmap' field in favor of taking it from the parent's node.

Make the probe() code a bit simpler and shorter by storing all the '&pdev->dev' as 'dev'. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20230901120057.47018-2-krzysztof.kozlowski@linaro.org Signed-off-by: Sebastian Reichel

power: reset: syscon-poweroff: use builtin_platform_driver() to simplify code

2023-09-12T18:25:54+00:00

The syscon_poweroff_register() doesn't do anything special, so it can use the builtin_platform_driver() macro to eliminate boilerplate code. Signed-off-by: Yang Yingliang Link: https://lore.kernel.org/r/20230807131951.3443880-6-yangyingliang@huawei.com Signed-off-by: Sebastian Reichel

power: Explicitly include correct DT includes

2023-07-19T20:47:03+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.

power: reset: syscon-poweroff: add a mask property

2017-04-13T23:41:33+00:00

Make the syscon-poweroff driver accept value and mask instead of just value. Prior to this patch, the property name for the value was 'mask'. If only the mask property is defined on a node, maintain compatibility by using it as the value. Signed-off-by: Guy Shapiro Acked-by: Rob Herring Signed-off-by: Sebastian Reichel
