From 94cc409be782a3fdbf86a4f8c9dd8c93e0fea395 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 12 Mar 2013 14:14:37 +0000 Subject: [PATCH] staging: comedi: adv_pci1710: restore PCI-1710HG support The Advantech PCI-1710HG is similar to the PCI-1710 but has a different set of ranges for analog input (HG = high gain). Because they share the same PCI vendor and device ID, the adv_pci1710 driver does not currently distinguish them. This is more of a problem since auto-configuration code was added to the driver (and manual configuration support removed), as the PCI-1710HG would be automatically configured as a PCI-1710. More recently, the unused code for PCI-1710HG support was #ifdef'ed out. In fact, the PCI-1710 and PCI-1710HG can be distinguished by considering the PCI subvendor and subdevice IDs according to the following table: vendor device subven subdev model treat as ====== ====== ====== ====== ============ ========== 0x13fe 0x1710 0x10b5 0x9050 PCI-1710S PCI-1710 0x13fe 0x1710 0x13fe 0x0000 PCI-1710 PCI-1710 0x13fe 0x1710 0x13fe 0xb100 PCI-1710B PCI-1710 0x13fe 0x1710 0x13fe 0xb200 PCI-1710B2 PCI-1710 0x13fe 0x1710 0x13fe 0xc100 PCI-1710C PCI-1710 0x13fe 0x1710 0x13fe 0xc200 PCI-1710C2 PCI-1710 0x13fe 0x1710 0x1000 0xd100 PCI-1710U PCI-1710 0x13fe 0x1710 0x13fe 0x0002 PCI-1710HG PCI-1710HG 0x13fe 0x1710 0x13fe 0xb102 PCI-1710HGB PCI-1710HG 0x13fe 0x1710 0x13fe 0xb202 PCI-1710HGB2 PCI-1710HG 0x13fe 0x1710 0x13fe 0xc102 PCI-1710HGC PCI-1710HG 0x13fe 0x1710 0x13fe 0xc202 PCI-1710HGC2 PCI-1710HG 0x13fe 0x1710 0x1000 0xd102 PCI-1710HGU PCI-1710HG The above information is extracted from Advantech's own GPL'ed Linux (non-Comedi) driver source from "advdaq-1.10.0001-1.tar.bz2" on their website. (0x13fe = PCI_VENDOR_ID_ADVANTECH, 0x10b5 = PCI_VENDOR_ID_PLX, 0x9050 = PCI_DEVICE_ID_PLX_9050, 0x1000 = PCI_VENDOR_ID_NCR or PCI_VENDOR_ID_LSI_LOGIC but I assume this subvendor ID was chosen "randomly".)
