2023-07-19clk: Explicitly include correct DT includesRob Herring
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.

2023-04-10clk: uniphier: Use managed `of_clk_add_hw_provider()`Lars-Peter Clausen
Use the managed `devm_of_clk_add_hw_provider()` instead of `of_clk_add_hw_provider()`. This makes sure the provider gets automatically removed on unbind and allows to completely eliminate the drivers `remove()` callback.

2023-03-28clk: uniphier: Convert to platform remove callback returning voidUwe Kleine-König
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.

2017-01-26clk: uniphier: continue probing even if some clocks fail to registerMasahiro Yamada
Do not let the entire probe function fail even if some clocks fail to register. Let's continue with succeeded clocks. This will give the system more chances to boot and allow us to investigate the cause of the failure.

2016-12-07clk: uniphier: add CPU-gear change (cpufreq) supportMasahiro Yamada
Core support code for CPU frequency changes, which will be used by the generic cpufreq driver. The register view is different from the generic clk-mux; it has a separate status register, and an update bit to load the register setting.

2016-10-19clk: uniphier: rename MIO clock to SD clock for Pro5, PXs2, LD20 SoCsMasahiro Yamada
I made a mistake as for naming for this block. The MIO block is not implemented for these 3 SoCs in the first place. The current naming will be a trouble if an SoC with both MIO and SD-ctrl blocks appear in the future. This driver has just been merged in the previous merge window. Rename it before the release.
