JIRA: https://issues.redhat.com/browse/RHEL-24205 commit 4bebd644971c2b5355af60f4828d464b3268e6cc Author: Max Filippov <jcmvbkbc@gmail.com> Date: Wed Oct 18 12:12:52 2023 -0700 serial/esp32_uart: use prescaler when available esp32s3 variant of the esp32 UART has limited baudrate divisor range that does not allow it to use 9600 and lower rates with 40MHz input clock. Use clock prescaler present in this UART variant to help with that.
