    drivers: char: Enable OMAP UART driver for TI K3 devices
    
    TI K3 devices (J721E, J721S2, AM62X .etc) have the same variant
    of UART as OMAP4. Add the compatible used in Linux device tree,
    "ti,am654-uart" to the OMAP UART dt_match so that the driver can
    be used with these devices. Also, enable the driver for ARM64
    platforms.

          This selects the Texas Instruments OMAP UART. If you have a Texas
