2024-06-03clk: stm32mp2: use of STM32 access controllerGabriel Fernandez1-1/+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.

2023-12-17clk: stm32mp1: use stm32mp13 reset driverGabriel Fernandez1-4/+1
STM32MP15 is now using the same reset driver as STM32MP13 as they have the same binding requirement. Signed-off-by: Gabriel Fernandez <gabriel.fernandez@foss.st.com> Link: https://lore.kernel.org/r/20231208143700.354785-3-gabriel.fernandez@foss.st.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2022-05-20clk: stm32mp13: add safe mux managementGabriel Fernandez1-0/+1
Some muxes need to set a the safe position when clock is off. Signed-off-by: Gabriel Fernandez <gabriel.fernandez@foss.st.com> Link: https://lore.kernel.org/r/20220516070600.7692-12-gabriel.fernandez@foss.st.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2022-05-20clk: stm32mp13: add multi mux functionGabriel Fernandez1-0/+2
Some RCC muxes can manages two output clocks with same register. Signed-off-by: Gabriel Fernandez <gabriel.fernandez@foss.st.com> Link: https://lore.kernel.org/r/20220516070600.7692-11-gabriel.fernandez@foss.st.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2022-05-20clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)Gabriel Fernandez1-0/+92
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.
