* clk: en7523: fix rate divider for slic and spi clocksLorenzo Bianconi2024-07-081-2/+7
| | | | | | | | | | | | | Introduce div_offset field in en_clk_desc struct in order to fix rate divider estimation in en7523_get_div routine for slic and spi fixed rate clocks. Moreover, fix base_shift for crypto clock.

* clk: Explicitly include correct DT includesRob Herring2023-07-191-2/+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: en7523: Add clock driver for Airoha EN7523 SoCFelix Fietkau2022-04-231-0/+351
This driver only registers fixed rate clocks, since the clocks are fully initialized by the boot loader and should not be changed later, according to Airoha.
