223 * Restore one of the GPIO banks that was saved during suspend. This is

225 * from the order that the CON and DAT registers are set in.
226 *
227 * The three states the pin can be are {IN,OUT,SFN} which gives us 9
228 * combinations of changes to check. Three of these, if the pin stays
229 * in the same configuration can be discounted. This leaves us with
230 * the following:
231 *
232 * { IN => OUT } Change DAT first
233 * { IN => SFN } Change CON first
234 * { OUT => SFN } Change CON first, so new data will not glitch
235 * { OUT => IN } Change CON first, so new data will not glitch
236 * { SFN => IN } Change CON first
237 * { SFN => OUT } Change DAT first, so new data will not glitch [1]
238 *
239 * We do not currently deal with the UP registers as these control
240 * weak resistors, so a small delay in change should not need to bring
241 * these into the calculations.
242 *
243 * [1] this assumes that writing to a pin DAT whilst in SFN will set the
244 * state for when it is next output.
