Thanks for the link. OK, then, as the linux tda998x driver handles only the tda 19988 and 19989 chips, the HDMI I2C address is always 0x70. So, question: Russell and Sebastian, do you still want an other patch? Other question: the CEC address is hard-coded to 0x34 in the driver. Should it be configurable in the DT? -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
