Currently, the demod of PT3 card (tc90522) gets RSSI data from the connected tuner (mxl301rf) via tuner_ops.get_signal_strength_dbm() and sets property cache in fe->ops.get_frontend() (which is called before returning property cache value by dvb_frontend_ioctl_properties()). If the tuner driver should set property cache directly, when is the right timing to do so? In fe->ops.tuner_ops.get_status() ? or in the old fe->ops.tuner_ops.get_signal_strength()? or Should I change get_signal_strength_dbm(fe, s64 *) to update_signal_strength(fe) and let the tuner driver set property cache there? -- akihiro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
