Subject: [PATCH v2 5/7] tty: serial: meson: add independent uart_data for A1 SoC family
Date: Wed, 5 Jul 2023 21:18:31 +0300 [thread overview]
Message-ID: <20230705181833.16137-6-ddrokosov@sberdevices.ru> (raw)
In-Reply-To: <20230705181833.16137-1-ddrokosov@sberdevices.ru>
Implement separate uart_data to ensure proper devname value for the A1
SoC family. Use 'ttyS' devname, as required by the A1 architecture,
instead of the legacy gx architecture.
