From bd86980b5113e3bf59ad096c49bf5c39dbca8880 Mon Sep 17 00:00:00 2001 From: Dmitry Rokosov Date: Wed, 5 Jul 2023 21:18:30 +0300 Subject: [PATCH] tty: serial: meson: introduce separate uart_data for S4 SoC family In order to use the correct devname value for the S4 SoC family, it is imperative that we implement separate uart_data. Unlike the legacy g12a architecture, the S4 architecture should employ the use of 'ttyS' devname.
