From be32c0cf0462c36f482b5ddcff1d8371be1e183c Mon Sep 17 00:00:00 2001 From: Soeren Grunewald Date: Thu, 11 Jun 2015 09:25:04 +0200 Subject: [PATCH] serial: 8250_pci: Add support for 12 port Exar boards The Exar XR17V358 can also be combined with a XR17V354 chip to act as a single 12 port chip. This works the same way as the combining two XR17V358 chips. But the reported device id then is 0x4358.
