By cross-checking STMPE 610/801/811/1601/2401/2403 datasheets,
it appears that edge detection and rising/falling edge detection
is not supported by all STMPE variant:

GPIO GPIO
Edge detection rising/falling
edge detection
610 | X | X |
801 | | |
811 | X | X |
1600 | | |
1601 | X | X |
1801 | | X |
2401 | X | X |
2403 | X | X |

Rework stmpe_dbg_show_one() and stmpe_gpio_irq to correctly
take these cases into account.

Very nice.

I expect this to go into the MFD tree with the rest, I guess
Lee will cook me an immutable branch for the whole thing
once he's happy with it.

Hi Linus

I will send a v2 as warnings as been detected by kbuild test robot

Thanks
