This creates a new framework for handling of pin control devices, i.e. devices that control different aspects of package pins.
This uclass handles pinmuxing and pin configuration; pinmuxing controls switching among silicon blocks that share certain physical pins, pin configuration handles electronic properties such as pin- biasing, load capacitance etc.
This framework supports the same device tree bindings, but if you do not need full interface support, you can disable some features to reduce memory foot print.

Just checking on the status of this patch - it would be great to move this forward and apply it soon. The rockchip series now depends on it.
