From: Patrice Chotard <patrice.chot...@st.com>
This series update the serial_stm32x7 driver used by both STM32F7 and STM32H7
SoCs :
_ clean the code by using BIT and GENMASK macro
_ remove useless CLK and OF_CONTROL flags
_ add fifo support for H7
_ introduce STM32F4 support
Currently, STM32F4 uses a dedicated serial driver drivers/serial/serial_stm32.c.
whereas STM32F7 and STM32H7 uses drivers/serial/serial/serial_stm32x7.c .
There is no reason to have 2 separate serial driver for STM32 SoCs family.
It's the first step to prepare STM32F4 conversion to driver model and
device tree support. Hence this conversion will be done, serial_stm32x7.c
driver will support alls SoCs (ie F4/F7 and H7) it will be then renamed with
the generic name serial_stm32.c
Patrice Chotard (6):
serial: stm32x7: cleanup code
serial: stm32x7: remove stm32f7-usart and stm32h7-usart compatible
serial: stm32x7: prepare the ground to STM32F4 support
serial: stm32x7: add fifo support for STM32H7
serial: stm32x7: add STM32F4 support
serial: stm32x7: remove useless CONFIG_CLK and OF_CONTROL flag
