* clk: Explicitly include correct DT includesRob Herring2023-07-191-1/+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.

| | * clk: xilinx: Convert to platform remove callback returning voidUwe Kleine-König2023-03-282-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | xvcu_remove() is only called for a device after after xvcu_probe() completed successfully. In that case dev_set_drvdata() was called for that device with a non-NULL parameter, so platform_get_drvdata() won't return NULL and the if condition is never true. Drop the if, preparing a conversion to make platform driver's remove callback return void.

The xlnx_vcu driver is actually a clock controller driver which provides clocks that can be used by a driver for the encoder/decoder units. There is no reason to keep this driver in soc. Move the driver to clk. NOTE: The register mapping actually contains registers for AXI performance monitoring, but these are not used by the driver.
