From: H Hartley Sweeten Date: Thu, 6 Jun 2013 22:38:04 +0000 (-0700) Subject: staging: comedi: pcl730: add support for the PCL-733 ISA board X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=82e71174ae2a67722c6131ffcad402f79f5a2702;p=linux-beck.git staging: comedi: pcl730: add support for the PCL-733 ISA board The PCL-733 ISA board can be supported by this driver. This board has 32 isolated digital inputs. Add support for the PCL-733 board to the pcl730 driver and remove it from the poc driver.
