22 List of parent clocks suitable for UART from following set:
23 "TBG-A-P", "TBG-B-P", "TBG-A-S", "TBG-B-S", "xtal"
24 UART clock can use one from this set and when more are provided
25 then kernel would choose and configure the most suitable one.
26 It is suggest to specify at least one TBG clock to achieve
27 baudrates above 230400 and also to specify clock which bootloader
28 used for UART (most probably xtal) for smooth boot log on UART.
