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