[PATCH 3/3] staging: comedi: addi_apci_1564: tidy register map defines

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit performs a final tidying of the register map defines, bringing
them to a state that is ready for merging into addi_apci_1564.c when the
time comes.  Actions performed include:

*Removes the APCI1564_ADDRESS_RANGE macro, which is no longer needed/used.
*Renames the APCI1564_DIGITAL_OP_{VCC,CC}_INTERRUPT_{ENABLE,DISABLE}
macros to shorter names which are more consistent with the digital input
interrupt macros.
*Fixes a typo in a comment (dev>iobase changed to dev->iobase).
*Renames the APCI1564_TCW_* macros to APCI1564_COUNTER_* names to more
accurately reflect that they are only offsets to counter registers (since
only the counters are offset from dev->iobase).
