* clk: stm32mp2: use of STM32 access controllerGabriel Fernandez2024-06-031-1/+1
| | | | | | | | | Use an STM32 access controller to filter the registration of clocks. If a clock is used by the security world, then it must not registered.

* clk: stm32mp1: use stm32mp13 reset driverGabriel Fernandez2023-12-171-1/+8
| | | | | | | | | STM32MP15 is now using the same reset driver as STM32MP13 as they have the same binding requirement.

* clk: stm32: Convert to platform remove callback returning voidUwe Kleine-König2023-03-281-4/+2
| | | | | | | | | | | | | | | | | 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: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)Gabriel Fernandez2022-05-201-0/+520
This driver manages Reset and Clock of STM32MP13 soc. It uses a clk-stm32-core module to manage stm32 gate, mux and divider for STM32MP13 and for new future soc. All gates, muxes, dividers are identify by an index and information are stored in array (register address, shift, with, flags...) This is useful when we have two clocks with the same gate or when one mux manages two output clocks.
