This series adjusts the serial and GPIO drivers, used by Beaglebone for example, to work with driver model. Since there are still boards using these drivers but not driver model, this adds new functionality rather than replacing what exists.
Several patches tweak and fix the existing driver model serial and GPIO implementation.
There are two Beaglebone Black configurations:
- Device tree control with verified boot - No device tree control
The first uses device tree to select the serial console and provide information needed by the serial driver (similar to how things work on Tegra). The second uses platform data provided by a common board file.
Both are converted, so this is a good example of how to support both device tree and platform data if needed.
