      [ARM] tegra: pinmux: add safe values, move tegra2, add suspend · c5f04b8d
      Colin Cross authored 
      - the reset values for some pin groups in the tegra pin mux can result in
functional errors due to conflicting with actively-configured pin groups
muxing from the same controller. this change adds a known safe, non-
conflicting mux for every pin group, which can be used on platforms
where the pin group is not routed to any peripheral

- also add each pin group's I/O voltage rail, to enable platform code to
map from the pin groups used by each interface to the regulators used
for dynamic voltage control

- add routines to individually configure the tristate, pin mux and pull-
ups for a pingroup_config array, so that it is possible to program
individual values at run-time without modifying other values.
this allows driver power-management code to reprogram individual
interfaces into lower power states during idle / suspend, or to
reprogram the pin mux to support multiple physical busses per
internal controller (e.g., sharing a single I2C or SPI controller
across multiple pin groups)

- move chip-specific data like pingroups and drive-pingroups
out of the common code and into chip-specific code

- fix debug output for group with no pullups

- add a TEGRA_MUX_SAFE function.  Setting a pingroup to TEGRA_MUX_SAFE
will automatically select a mux setting that is guaranteed not to
conflict with any of the hardware blocks.

      [ARM] tegra: add suspend and mirror irqs to legacy controller · 460907bc
      Gary King authored 
      mirror IRQ enable and disable operations on the legacy PPI system
interrupt controller, since the legacy controller is responsible
for responding to wakeup interrupts when the CPU is in LP2 idle mode

save the irq controller state on suspend and restore on resume

      [ARM] tegra: Add legacy irq support · 8726e4f5
      Colin Cross authored 
      The "legacy irq controller" duplicates the functionality of the GIC,
but remains powered during the cpu suspend and idle modes that power
down the CPU and the GIC.
