2015-03-04ARM: tegra: pinmux: support hsm/schmitt on pinsStephen Warren
T210 support HSM and Schmitt options in the pinmux register (previous chips placed these options in the drive group register). Update the code to handle this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-03-04ARM: tegra: pinmux: partially handle varying register layoutsStephen Warren
Tegra210 moves some bits around in the pinmux registers. Update the code to handle this. This doesn't attempt to address the issues with the group-to-group varying drive group register layout mentioned earlier. This patch handles the SoC-to-SoC differences in the mux register layout.

2015-03-04ARM: tegra: pinmux: move some type definitionsStephen Warren
On some future SoCs, some per-drive-group features became per-pin features. Move all type definitions early in the header so they can be enabled irrespective of the setting of TEGRA_PMX_SOC_HAS_DRVGRPS.

2015-03-04ARM: tegra: pinmux: handle feature removal on newer SoCsStephen Warren
On some future SoCs, some of the per-drive-group features no longer exist. Add some ifdefs to support this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2015-03-04ARM: tegra: pinmux: simplify some definesStephen Warren
Future SoCs have a slightly different combination of pinmux options per pin. This will be simpler to handle if we simply have one define per option, rather than grouping various options together, in combinations that don't align with future chips.

2015-03-04ARM: tegra: pinmux: add note re: drive group field definesStephen Warren
Tegra's drive group registers have a remarkably inconsistent layout. The current U-Boot driver doesn't take this into account at all. Add a comment to describe the issue, so at least anyone debugging the driver will be aware of this. To solve this, we'd need to add a per-drive-group data structure describing the layout for the individual register. Since we don't set up too many drive groups in U-Boot at present, this hopefully isn't causing too much practical issue. Still, we probably need to fix this sometime. Wth Tegra210, the register layout becomes almost entirely consistent, so this problem partially solves itself over time.

This is needed to correctly apply the new Jetson TK1 pinmux config. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
