[GitHub] [incubator-nuttx] davids5 opened a new pull request #2471: Pr imx serial

davids5 opened a new pull request #2471:
URL: https://github.com/apache/incubator-nuttx/pull/2471


   ## Summary
    
   - Updated to Apache License 
   
   - imxrt:imxrt_lowputc Fixed parity settings.
      
      imxrt UART must be placed in 9 bit mode (M=1) with when 8 bit
      data with parity is required. If left in 8 bit mode (M=0) with
      parity then D7 of the TX/RX register becomes parity bit. Hence
      what is called 9-bit or 8-bit Mode Select is a misnomer.
      8 bit mode when parity is enabled is realy 7 bit with parity.
   
    - imxrt:serial support single-wire mode
   
   ## Impact
   
   We loose our individual attribution.
   
   The LPUARTs will work correctly when parity is set to O or E.
   
   None: The LPUARTs will support single wire mode now. But the defeult is IMXRT_LPUART_SINGLEWIRE off.
   
   ## Testing
   
   nxp_fmurt1062-v1 rev B.  Using PX4 SBUS.
