From d0445303f86c6ace7dcaf6d2806445ea0208f151 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 13 Nov 2015 11:11:23 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: fix counter 0 internal clock source There are a number of descrepencies in the various manuals for the boards that this driver supports. Some show a 10 MHz clock for counters 1 and 2 others show a 1 MHz clock. Counter 0 can use either a div 10 of that clock or an external clock (up to 10 MHz). Currently this driver initializes counters 1 and 2 with a 10 MHz clock. For consistency, return 1 MHz (10 MHz/10) for counter 0 when the user queries the internal clock source with INSN_CONFIG_GET_CLOCK_SRC.
