+Subject: serial: fsl_lpuart: RS485 RTS polariy is inverse
+
+From: Shenwei Wang <shenwei.wang@nxp.com>
+
+commit 846651eca073e2e02e37490a4a52752415d84781 upstream.
+
+The setting of RS485 RTS polarity is inverse in the current driver.
+
+When the property of 'rs485-rts-active-low' is enabled in the dts node,
+the RTS signal should be LOW during sending. Otherwise, if there is no
+such a property, the RTS should be HIGH during sending.
+
+Fixes: 03895cf41d18 ("tty: serial: fsl_lpuart: Add support for RS-485")
