the Ci failure is due to #100426

CLOCK_INIT_CORE_CLOCK is defined as 12MHz, which one is right?

it should be 12000000, will correct in new commit, thanks.

just confirm the reason behind, why all the lpuart instances share the same dma channel 4 and 5?

fixed in new commit, thanks for the founding, it was caused by incorrect copy-paste :)

In frdm_mcxa577.yaml the flash is 640, here is 2M, is that a mismatch?

2M is correct, will update frdm_mcxa577.yaml in new commit, thanks.

In index.rst 49, it says "The MCX-A577 SoC is configured to use FRO running at 180MHz as a source for the system clock.", here is 12000000, is that a mismatch?

it is a problem, will update to 12000000. the 12000000 is for FPGA, need further update after testing with silicon.

should be LPUART0, will update in new commit

just confirm, does any driver support resets? if yes, please add the reset line in the node.

Did not find driver support the reset, so not add the reset line in current commit.
