Describe the shared input clock, audio DAI, TV encoder display graph and optional bandgap calibration in one parent node. The codec and TV encoder do not need separate firmware nodes. AC_LDOIN and TV_VCC are distinct 3.3 V supply inputs. Describe them separately without requiring different external regulators. Require the audio supply when the DAI is described and the video supply when the display graph is present, while allowing PHY-only configurations. Describe the optional shared INTB connection without an internal interrupt domain. Cable detection status remains readable over I2C when INTB is not connected. Include wired and unwired examples. The Ethernet PHY is represented by a PHY package on its MDIO bus, with a phandle back to this device for access to the package control registers. It therefore does not require an MFD child node. The input clock must run at 24 or 27 MHz when the Ethernet PHY is used, matching the rates encoded by its documented clock selector.
