* ARM: tegra: use DT bindings for GPIO namingStephen Warren2016-05-31-0/+2
| | | | | | | | | | There are currently many places that define the list of all Tegra GPIOs; the DT binding header and custom Tegra-specific header file gpio.h. Fix the redundancy by replacing everything with the DT binding header file.

* tegra: Convert tegra GPIO driver to use driver modelSimon Glass2014-09-10-6/+9
| | | | | | | | | | | | | | | | This is an implementation of GPIOs for Tegra that uses driver model. It has been tested on trimslice and also using the new iotrace feature. The implementation uses a top-level GPIO device (which has no actual GPIOS). Under this all the banks are created as separate GPIO devices. The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7, ..., Z0..Z7, AA0..AA7, etc. Since driver model is not yet available before relocation, or in SPL, a special function is provided for seaboard's SPL code.

* ARM: tegra: add GPIO initialization table functionStephen Warren2014-05-13-0/+20
| | | | | | | | | | | The HW-defined procedure for booting Tegra requires that some pins be set up as GPIOs immediately at boot in order to avoid glitches on those pins, when the pinmux is programmed. Add a feature to the GPIO driver which executes a GPIO configuration table. Board files will use this to implement the correct HW initialization procedure.

* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-0/+40
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK. Signed-off-by: Tom Warren <twarren@nvidia.com>
