STM32MP25 got the same serial hardware block as STM32MP1x but with two improvements:
 - TX and RX FIFO have been extended to 64 bytes.
 - one instance more than in STM32MP1x series.

Valentin Caron (4):
  serial: stm32: implement prescaler tuning to compute low baudrate
  serial: stm32: extend max number of U(S)ART to 9
  serial: stm32: change register's offset type from u8 to u16
  serial: stm32: get FIFO size from hwcfg register
