rob,

In drivers/gpu/drm/msm/hdmi/hdmi.c , in TODO audio , do we need to change
the codec settings for audio, in case an analog audio is
connected/disconnected or hpd of hdmi.

irqreturn_t hdmi_irq(int irq, void *dev_id)
{
        struct hdmi *hdmi = dev_id;

        /* Process HPD: */
        hdmi_connector_irq(hdmi->connector);

        /* Process DDC: */
        hdmi_i2c_irq(hdmi->i2c);

        /* TODO audio.. */

        return IRQ_HANDLED;
}


Regards,
vinay simha
