serial: imx: Use generic uart-has-rtscts DT property (1006ed7e) · Commits · 戴 / test

Convert the Freescale IMX UART driver from using the vendor-specific "fsl,uart-has-rtscts" to the generic "uart-has-rtscts" DT property, as documented by the Generic Serial DT Bindings. The old vendor-specific property is still recognized by the driver for backwards compatibility, but deprecated. Signed-off-by:
