The objective of this series is to prepare the ground for future STM32H7 SoC introduction. As STM32F7 and STM32H7 SoCs shared several blocks (serial, qspi, gpio ....) some rework is needed to made some drivers more generic. Some of these driver are using proprietatry clock glue which need to be replace by clock framework one, which also implies stm32f7 clock driver rework.
Here are the steps: _ align stm32f7 clock DT declaration with kernel one _ retrieve RCC base address from DT _ replace the stm32f7 clock_get() glue function by clock framework clk_get_rate() inside several driver : _ drivers/spi/stm32_qspi.c _ drivers/serial/serial_stm32x7.c _ remove proprietary clock glue
Patrice Chotard (9): ARM: DTS: stm32: align DT clock declaration with kernel clk: stm32f7: add static for configure_clocks() clk: stm32f7: get RCC base address from DT clk: stm32f7: add clock .get_rate() callback clk: stm32f7: cleanup clocks unused definitions serial: stm32x7: migrate serial struct to driver serial: stm32x7: add clk_get_rate() support spi: stm32_qspi: add clk_get_rate() support clk: stm32f7: remove clock_get()
