clk: Explicitly include correct DT includes

2023-07-19T20:13:16+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.

clk: uniphier: Use managed `of_clk_add_hw_provider()`

2023-04-10T19:56:25+00:00

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.

clk: uniphier: Convert to platform remove callback returning void

2023-03-29T02:31:45+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 (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.

clk: uniphier: Fix fixed-rate initialization

2022-03-12T03:29:02+00:00

Fixed-rate clocks in UniPhier don't have any parent clocks, however, initial data "init.flags" isn't initialized, so it might be determined that there is a parent clock for fixed-rate clock. This sets init.flags to zero as initialization.

clk: uniphier: Fix potential infinite loop

2021-04-13T02:09:59+00:00

The for-loop iterates with a u8 loop counter i and compares this with the loop upper limit of num_parents that is an int type. There is a potential infinite loop if num_parents is larger than the u8 loop counter. Fix this by making the loop counter the same type as num_parents. Also make num_parents an unsigned int to match the return type of the call to clk_hw_get_num_parents.

clk: uniphier: Add SCSSI clock gate for each channel

2020-01-05T07:14:22+00:00

SCSSI has clock gates for each channel in the SoCs newer than Pro4, so this adds missing clock gates for channel 1, 2 and 3. And more, this moves MCSSI clock ID after SCSSI.
