From fe9ed6d2483fda55465f32924fb15bce0fac3fac Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Sun, 24 Feb 2019 12:58:02 +0100 Subject: serial: 8250_pxa: honor the port number from devicetree Like the other OF-enabled drivers, use the port number from the firmware if the devicetree specifies an alias: aliases { ... serial2 = &uart2; /* Should be ttyS2 */ } This is how the deprecated pxa.c driver behaved, switching to 8250_pxa messes up the numbering.
