This is used only once and might be better expanded
in-place instead.

It's a single statement macro and doesn't need
braces or a terminating ; and it shouldn't be
indented 2 tabs.

#define setDAC(off)							\
	POKE32(MISC_CTRL,						\
	       FIELD_VALUE(PEEK32(MISC_CTRL), MISC_CTRL, DAC_POWER,	\
			   off))
