H A D | pcf_isa.c | diff 129893 Mon May 31 12:24:21 MDT 2004 nsouch Necessary modifications do get pcf working again for ISA. Tested with my Elektor card. Note that the hints are necessary to specify the IO base of the pcf chip. This enables to check the IO base when the probe routine is called during ISA enumeration. The interrupt driven code is mixed with polled mode, which is wrong and produces supposed spurious interrupts at each access. I still have to work on it. |
