[WATCHDOG] w83697hf/hg WDT driver - patch 1
This is patch 1 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.
This patch contains following changes:
- the note concerning tyan motherboards has been copied from
another driver, This doesn't apply here.
- the comments concerning CRF6 are wrong as CRF3 is manipulated
and CRF6 is never read nor written.
- the comments concerning CRF5 are wrong as CRF4 is manipulated
and CRF5 is never read nor written.
