Subject: [PATCH 2/2] serial: 8250_omap: Add support for AM654 UART controller
Date: Tue, 19 Jun 2018 14:44:50 -0500 [thread overview]
Message-ID: <20180619194450.6353-3-nm@ti.com> (raw)
In-Reply-To: <20180619194450.6353-1-nm@ti.com>
AM654 uses a UART controller that is compatible (partially) with
existing 8250 UART, however, has a few differences with respect to DMA
support and control paths. Introduce a base definition that allows us
to build up the differences in follow on patches.
