re-assigned to platform owner, no changes to DMA API in PR, all soc, dts, and driver changes from what I can tell. |

rebased, fixed conflict, added mcxw71 overlay to test @hakehuang i cannot get uart async test to pass on main with other platform mcxa153, so I am thinking there is something wrong with the uart driver or test, are you able to get any lpuart platform on main passing ? |

below is the failure platform. rt5/6xx is due to the mpu region issues, frdm_ke17z512 and lpc55 series are due to board design issue. I send you the full report.

I would recommend to add dut_lpuart0_loopback.overlay, change from ut_lpuart0_loopback.overlay, as lpuart ip has a internal loopback. no need to fly wire. and in frdm_mcxw72, lpuart1 is reused with can and used by mculink as uart interface.

for frdm_mcxw71 we can not use lpuart1, as this is used as default uart, we need use lpuart0 with loopback mode
dut_lpuart0_loopback.overlay
