Thanks, Beware we will need to keep old DT with new kernel functional for a while, do removal of component & HHI in meson_dw_hdmi would need to wait for multiple kernel releases. A migration step would be to add a phandle to hhi right now, so we can drop components earlier, then in a second time add a proper PHY and then mark the hhi reg as deprecated.
