3 * COMEDI driver for Advantech PCI-1720U
9 * COMEDI - Linux Control and Measurement Device Interface
15 * Description: 4-channel Isolated D/A Output board
16 * Devices: [Advantech] PCI-7120U (adv_pci1720)
18 * Updated: Fri, 29 Oct 2015 17:19:35 -0700
23 * The PCI-1720 has 4 isolated 12-bit analog output channels with multiple
27 * The analog outputs can operate in two modes, immediate and synchronized.
28 * This driver currently does not support the synchronized output mode.
35 * Jumper JP5 controls the "hot" reset state of the analog outputs.

18 * The DP83TG720 1000BASE-T1 PHY has several limitations that require
19 * software-side mitigations. These workarounds are implemented throughout
23 * 1. Unreliable Link Detection and Synchronized Reset Deadlock
24 * ------------------------------------------------------------
34 * However, in point-to-point setups where both link partners use the same
35 * driver (e.g. Linux on both sides), a synchronized reset pattern may emerge.
36 * This leads to a deadlock, where both PHYs reset at the same time and
37 * continuously miss each other during auto-negotiation.
39 * To address this, the reset procedure includes two components:
