From: Thierry Reding <treding@xxxxxxxxxx> This patch series changes the pin controller DT description on Tegra194 in order to properly describe how the hardware works. Currently a simplified description is used that merges two pin controller instances (called AON and main) into a single DT node. This has some disadvantages such as creating a complicated mapping between the pins in those pin controllers and the corresponding GPIO controllers (which are already separated). As a prerequisite, the first patch in this series converts the device tree bindings to json-schema. A second patch then adds an additional compatible string for the AON instance (along with more details about each controller's pins) and finally patch 3 converts the driver to cope with these changes. A fourth patch makes the corresponding changes in the Tegra194 DTS file. Note that while this changes the DT node in an incompatible way, this doesn't have any practical implications for backwards-compatibility. The reason for this is that device trees have only reconfigured a very narrow subset of pins of the main controller, so the new driver will remain backwards-compatible with old device trees.
