Subject: [PATCH v2 0/5] serial: add drivers for the ESP32xx serial devices

Hello,

this series adds drivers for the UART and ACM controllers found in the
Espressif ESP32 and ESP32S3 SoCs.

Changes v1->v2:
- address review comments, listed in each patch
- add cleanup for the uart_get_baud_rate function

Max Filippov (5):
  serial: core: tidy invalid baudrate handling in uart_get_baud_rate
  dt-bindings: serial: document esp32-uart
  drivers/tty/serial: add driver for the ESP32 UART
  dt-bindings: serial: document esp32s3-acm
  drivers/tty/serial: add ESP32S3 ACM device driver
