@ -51,7 +51,7 @@ PIN Numbers
-----------
Each pin has an unique number associated with it in regs-gpio.h,
eg S3C2410_GPA0 or S3C2410_GPF1. These defines are used to tell
eg S3C2410_GPA(0) or S3C2410_GPF(1). These defines are used to tell
the GPIO functions which pin is to be used.

*
* Restore one of the GPIO banks that was saved during suspend. This is
* not as simple as once thought, due to the possibility of glitches
* from the order that the CON and DAT registers are set in.
*
* The three states the pin can be are {IN,OUT,SFN} which gives us 9
* combinations of changes to check. Three of these, if the pin stays
* in the same configuration can be discounted. This leaves us with
* the following:
*
* { IN => OUT } Change DAT first
* { IN => SFN } Change CON first
* { OUT => SFN } Change CON first, so new data will not glitch
* { OUT => IN } Change CON first, so new data will not glitch
* { SFN => IN } Change CON first
* { SFN => OUT } Change DAT first, so new data will not glitch [1]
*
* We do not currently deal with the UP registers as these control
* weak resistors, so a small delay in change should not need to bring
* these into the calculations.
*
* [1] this assumes that writing to a pin DAT whilst in SFN will set the
* state for when it is next output.

* The three states the pin can be are {IN,OUT,SFN} which gives us 9

* in the same configuration can be discounted. This leaves us with
* the following:
*
* { IN => OUT } Change DAT first
* { IN => SFN } Change CON first
* { OUT => SFN } Change CON first, so new data will not glitch
* { OUT => IN } Change CON first, so new data will not glitch
* { SFN => IN } Change CON first
* { SFN => OUT } Change DAT first, so new data will not glitch [1]
*
* We do not currently deal with the UP registers as these control
* weak resistors, so a small delay in change should not need to bring
* these into the calculations.
*
* [1] this assumes that writing to a pin DAT whilst in SFN will set the
