Subject: [PATCH 9/9] serial: max3100: use new UPIO_BUS as iotype
Date: Thu, 23 Apr 2026 16:15:09 -0400 [thread overview]
Message-ID: <20260423-tty-upio-v1-9-baf82d3b86d1@dimonoff.com> (raw)
In-Reply-To: <20260423-tty-upio-v1-0-baf82d3b86d1@dimonoff.com>
From: Hugo Villeneuve <hvilleneuve@dimonoff.com>
Now that we have a new UPIO_BUS I/O type, use it to register our serial
port. This allows the driver to work properly when using DT where
membase/iobase are not set.
