Subject: [PATCH v4] serial: exar: Add support for Sealevel 7xxxC serial cards
Date: Thu, 19 Jan 2023 14:40:29 -0500 (EST) [thread overview]
Message-ID: <alpine.DEB.2.21.2301191440010.22558@tstest-VirtualBox> (raw)
From: Matthew Howell <matthew.howell@sealevel.com>
Add support for Sealevel 7xxxC serial cards.
This patch:
* Adds IDs to recognize 7xxxC cards from Sealevel Systems.
* Updates exar_pci_probe() to set nr_ports to last two bytes of primary dev
ID for these cards.
Signed-off-by: Matthew Howell <matthew.howell@sealevel.com>
---
v2: Moved "This patch..." above signed-off line.
v3: "Added From: Matthew Howell <matthew.howell@sealevel.com>" to
submission.
v4: Insert patch so it doesn't linewrap.
Let me know if I need to make any more changes.
