I'd just make the above an int, so we could set it to -1 for that case. (value 0 is after all a valid reg).
It's a problem handling on rk3368, using -1 to judge means that we need initial the lcdsel_grf_reg to -1 on rk3368 platform, we need always add a platform data to handle it, seems not good enough. Since the hdmi chip data only use for vop selection, maybe we can judge with checking hdmi->chip_data == NULL for the case. Mark.
