How to contribute code to hal_nxp of zephyr


    I found the following problem in hal nxp spi, and there is a corresponding solution, how should I submit these codes to hal_nxp, it seems that zephyr hal_nxp does not accpet the modiftion of the driver code.
Issue 1: LPSPI_MasterSetDelayTimes nt32_t realDelay is used, subsequent calculations may cause realDelay to overflow and produce incorrect delay data

Issue 2: LPSPI_MasterTransferComplete did not clear kLPSPI_TransferCompleteFlag, the other interrupts that followed may be treated as Transfer Complete, resulting in an abnormal reception status of zephyr spi

I am currently putting the modification method in the following PR, can someone please tell me the correct submission path. Thanks!
