It seems better way. As of now, all we need for HDMI DDC is i2c_adapter (including i2c phy), not i2c_client. > > There is quite strong rationale for this: > - DDC is always accessible on fixed addresses described in HDMI specification. > - HDMIPHY (including I2C address) is a part of HDMI IP and it is bound to > specific version of Exynos SoC > - no need to add virtual nodes in DTS You mean hdmiddc and hdmiphy nodes? If so, I think they are real nodes, not virtual nodes. Otherwise, plz give me more comments. Thanks, Inki Dae > - NVIDIA already use bindings to DDC bus instead of DDC client.
