[ts-7000] ts7250 - Port B,F GPIO ep93xx/gpio.c interrupt issue

["maquefel" <>]

Hello,

I am having troubles with gpio interrupt issue. According documentation for ep93xx ports A, B, F can be configured to generate interrupts.

I am using linux 2.6.34.14 with linux-2.6.34-ts7200_matt-6 (Matthieu Crapet patch) applied.

However arch/arm/march-ep93xx/gpio.c is handling only interrupts from port A. And doesn't react to port B.

Tested it with printk in ab port interrupt hadler:

static void ep93xx_gpio_ab_irq_handler(unsigned int irq, struct irq_desc *desc)

{

    unsigned char status;

    int i;

    printk(KERN_INFO "ep93xx_gpio_ab_irq_handler: irq=%u", irq);  // I know printk is terrible in irq_handlers!!!!

I configured interrupts via sysfs by:

 

echo both > gpio0/edge

echo both > gpio8/edge

And i dont' get reaction for port B and F. A port reacts smoothly, and i get printk message that interrupt occurred.

Can someone please give me and advice regarding this issue? I want interrupts on all ports (A,B,F) not just A.
