From cc6628f07e0d994f92f04cd71755a3bf95667a14 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 4 Mar 2024 14:27:13 +0200 Subject: serial: 8250_pxa: Switch to use uart_read_port_properties() Since we have now a common helper to read port properties use it instead of sparse home grown solution.
