If anyone has any objections, please let me know. ------------------ From: Nora Schiffer [ Upstream commit b8d785a9f360abcd6a6f8f10a2adf222f8494d66 ] UART1 operates in DCE mode, but the RTS/CTS pins were incorrectly configured using the DTE pinmux setting. Correct the pinmux to match DCE mode. Switching the RTS and CTS signals is fine for this board, as UART1 is routed to a pin header. Existing functionality is unaffected, as RTS/CTS could never have worked with the incorrect pinmux.
