CVS commit: src/sys/dev/ic

["Julian Coleman" <jdc%netbsd.org@localhost>]

Module Name:    src
Committed By:   jdc
Date:           Wed Sep 16 06:51:01 UTC 2026

Modified Files:
        src/sys/dev/ic: pcf8584.c pcf8584var.h

Log Message:
Add interrupt support to pcfiic.
Make the repeat-start logic in the non-interrupt case simpler.
Add comments to softc fields.

By using interrupts, we greatly reduce the system time and wall clock time
used during i2c operations.
On machines where interrupts are not supported, the front end can set
the sc_poll flag to true, and the driver will use the polling path.
