Note that this is different from I2C-over-AUX supported by the DPAUX controller. The register that configures these pads is part of the DPAUX controllers register set and so a pinctrl driver is being added for the DPAUX device to share these pads. Add the device-tree binding documentation for the DPAUX pad controller. Although there is only one group of pads associated with the DPAUX that can be multiplexed, the group still needs to be described by the binding. If the 'groups' property is not present in the binding, then the pads will not be allocated by the pinctrl core for a client and this would allow another client to re-configure the same pads that may already be in-use. Please note that although the "off" function for the DPAUX pads is not technically a pin-mux setting but more of a pin-conf setting it is simpler to expose these as a function so that the user can simply select either "aux", "i2c" or "off" as the current function/mode. Update the main DPAUX binding documentation to reference the DPAUX pad controller binding document and add the 'i2c-bus' subnode. The 'i2c-bus' subnode is used for populating I2C slaves for the DPAUX device so that the I2C driver core does not attempt to add the DPAUX pad controller nodes as I2C slaves.

These are configured using a three level mux, of which the first 2 levels can be treated as one. The direct parents of the SOR clock are the sor_safe, sor_brick and sor_src clocks, whereas the pll_d2_out0 and pll_dp clocks can be selected as parents of the sor_src clock via a second mux. Previous generations of Tegra have only supported eDP and LVDS with the SOR, where LVDS was never used on publicly available hardware. Clocking for this only ever required the first level mux (to select between sor_safe and sor_brick). Tegra210 has a new revision of the SOR that supports HDMI and hence needs to support the second level mux to allow selecting pll_d2_out0 as the SOR clock's parent. This second mux is knows as sor_src, and operating system software needs a reference to it in order to select the proper parent.
