I have been giving the opposite advice and I thought in general Rob H suggests against adding "/bits/ 8" unless it's absolutely needed (like for an array). One example from <http://lore.kernel.org/r/97cd8c1d98d7406347e4e48f4c7383a394a2ae93.1451997697.git.oreste.salerno@tomtom.com> > > + lp_intrvl = /bits/ 8 <0x0A>; > > If the size is not 32-bits, you need to state that in the description. > There is not really much point in making these 8-bit though. -Doug
