From 9d61423fd84d61a27a1ac7f61e50c8a8fb8b403e Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 3 Feb 2017 20:25:00 +0000 Subject: [PATCH 1/1] serial: 8250_pci: Add MKS Tenta SCOM-0800 and SCOM-0801 cards commit 1c9c858e2ff8ae8024a3d75d2ed080063af43754 upstream. The MKS Instruments SCOM-0800 and SCOM-0801 cards (originally by Tenta Technologies) are 3U CompactPCI serial cards with 4 and 8 serial ports, respectively. The first 4 ports are implemented by an OX16PCI954 chip, and the second 4 ports are implemented by an OX16C954 chip on a local bus, bridged by the second PCI function of the OX16PCI954. The ports are jumper-selectable as RS-232 and RS-422/485, and the UARTs use a non-standard oscillator frequency of 20 MHz (base_baud = 1250000).
