Rather than having a single tegra-pinctrl driver that determines whether it's running on Tegra20 or Tegra30, instead have separate drivers for each that call into utility functions to implement the majority of the driver. This change is based on review feedback of the SPEAr pinctrl driver, which had originally copied to Tegra driver structure. This requires that the two drivers have unique names. Update a couple spots in arch/arm/mach-tegra for the name change. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Linus Walleij <linus.walleij@linaro.org>
