+Subject: [PATCH 32/59] ARM: i.MX6: sb-fx6m: Fix uart1 rts/cts flow control
+
+According to the board schematics uart1 works in DCE mode only.
+Remove the DCEDTE mode flag in the uart1 properties.
+
+Set a correct value in the IOMUXC_UART2_UART_RTS_B_SELECT_INPUT register.
+This value lets connect RTS_B pad to ipp_uart_rts_b when UART is in DCE mode.
