Hi All,
Several gpio binding documents like the one for mxs have the following
in them:
- #interrupt-cells : Should be 2. The first cell is the GPIO number.
The second cell bits[3:0] is used to specify trigger type and level flags:
1 = low-to-high edge triggered.
2 = high-to-low edge triggered.
4 = active high level-sensitive.
8 = active low level-sensitive.
Does anybody know where this information is evaluated and how this is
passed to the driver?
I am working on i.MX (who would have guessed that) and I am trying to
connect a I2C device with an interrupt source connected to the gpio
interrupt controller. It works fine, only the irq level/edge flags
get lost somewhere.
What I have is:
maxtouch at 4b {
compatible = "mXT224";
reg = <0x4b>;
interrupt-parent = <&gpio7>;
interrupts = <13 2>;
};
Any idea how the maxtouch driver can use the 'high-to-low edge
triggered' information?
BTW. the i.MX GPIO binding document does not claim to support the flags,
but I assume it's just missing in the document, but there maybe also
something missing in the driver to support this.
Sascha

Hi Sascha,
Try to change the value of #interrupt-cells under gpio node from 1 to 2.
I forgot updating imx on this.
Regards,
Shawn

Ok, that does the trick. Should I create a patch or are you already in
the middle of doing so?

Yes, I'm cooking a patch for that.

Change the value of #interrupt-cells of gpio nodes from 1 to 2, so that
the gpio irq type can be specified in device tree. Also update binding
document to make it clear.
