    * fix(uart): Sets XTAL as clock source for uart
    
    C6 and H2 have problems after returning from light sleep. The baud rate seems to be off when APB is used as clock source.
    
    This fix solves the issue using a steady clock source.
    
    * fix(typo): Typo and commentaries
    
    Adds C2 in the XTAL list.
    
    * fix(uart): adjust get/set baudrate
    
    Fixes the functions for reading/writing UART baudrate by using IDF functions instead of HAL/LL.
    
    * fix(uart): uses REF_TICK for ESP32/S2
    
    * fix(uart): esp32/s2 baudrate > 1MHz
    
    Fixes the baudrate for ESP32 and ESP32-S2 when the baud rate is higher than 1MHz.
    REF_TICK is just 2MHZ and can handle up to 1MHZ baudrate.
    
    * fix(uart): rxTimeout minimum
    
    Default RxTimeout changed to the minimum = 1.
    When TICK_REF is used as clock source, this is mandatory,
    
    * ci(pre-commit): Apply automatic fixes
