List, TI OMAP4 has HDMI in and HDMI has only one IRQ. In its BSP, HDMI hpd is already registered with the IRQ line that showed in /proc/interrupts. Try to share the IRQ # with HDMI CEC using request_irq(133, omap4_cec_isr, IRQF_SHARED, "omap4 CEC", p_this) but returns error. Any idea will be appreciated. ---henry
