From 6ddcf9b486f134f1a1544c82b36b0876ef2f33e6 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Mon, 23 Nov 2015 12:54:50 -0500 Subject: gpio: Add GPIO support for the ACCES 104-IDI-48 The ACCES 104-IDI-48 family of PC/104 utility boards feature 48 individually optically isolated digital inputs. Enabled inputs feature change-of-state detection capability; if change-of-state detection is enabled, an interrupt is fired off if a change of input level (low-to-high or high-to-low) is detected. Change-of-state IRQs are enabled/disabled on 8-bit boundaries, for a total of six boundaries. This driver provides GPIO and IRQ support for these 48 channels of digital input. The base port address for the device may be configured via the idi_48_base module parameter. The interrupt line number for the device may be configured via the idi_48_irq module parameter.
