Revision 001851659354cce436b749a793f3512a53394d80 authored by Andres Salomon on 21 December 2010, 21:04:42 UTC, committed by Linus Torvalds on 23 December 2010, 23:31:48 UTC
The edge detect status GPIOs function differently from the other atomic
model CS5536 GPIO registers; writing 1 to the high bits clears the GPIO,
but writing 1 to the lower bits also clears the bit.

This means that read-modify-write doesn't actually work for it, so don't
apply the errata here.  If a negative edge status gets lost after
resume..  well, we tried our best!
