Hello Robert,

These patches break the build for some boards. e.g. corvus_defconfig


drivers/serial/atmel_usart.c: In function ‘atmel_serial_setbrg_internal’:
drivers/serial/atmel_usart.c:44:20: error: implicit declaration of
function ‘get_usart_clk_rate’ [-Werror=implicit-function-declaration]
   44 |         usart_hz = get_usart_clk_rate(id);
      |                    ^~~~~~~~~~~~~~~~~~
  AR      spl/disk/built-in.a
  CC      spl/fs/fs_internal.o
cc1: some warnings being treated as errors


Please have a look,
thanks,
Eugen
