Subject: [PATCH v2 7/9] ARM: dts: aspeed: Add aliases for UARTs
Date: Wed, 4 Oct 2017 17:19:15 +1030 [thread overview]
Message-ID: <20171004064917.2498-8-joel@jms.id.au> (raw)
In-Reply-To: <20171004064917.2498-1-joel@jms.id.au>
Existing userspace expects the console (UART5) to be at /dev/ttyS4. To
ensure the UARTs show up where users expect them, we give them fixed
aliases starting at 0.
