I'm using imx233 in a custom board according to fsl's schematic ...
in the linux bsp release (2.6.31) I want to change the operation of the imx23 PSWITCH pin such that:
- while in OFF state pressing PSWITCH will power up the imx23.... this is already implemented
- While in ON state pressing momentarily suspends/wakes the processor ... already implemented too.
BUT, this is what I want to add:
- while in ON state holding down PSWITCH for more than 3sec will shut down the system
Any help appreciated, ...
