You're right, the comment comes from the max77714-only driver, but now that it is in a multi-chip driver the confusion started to exist. > Please either drop this patch or rephrase it to clarify that it applies > to both chips. What if I rephrase to: /* * "If the value of TWD needs to be changed, clear the system * watchdog timer first [...], then change the value of TWD." - * (MAX77714 datasheet) + * (MAX77714 datasheet but applies to MAX77620 too) */ ? -- Luca
