[PATCH v2 1/7] ARM: tegra: Overhaul Venice2 regulators

[Thierry Reding]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Some of the regulators and the relationships to other regulators are
wrong. This commit attempts to rectify this by making them more similar
to what the schematics contain. This starts by adding a +VDD_MUX supply
that represents the 12V input and derives the main +3.3V_SYS and +5V_SYS
supplies from that. The majority of the other regulators derive from one
of those three.

While at it, rename the regulators to match the names in the schematics
to make them easier to match up.

Changes in v2:
- rename as3722_sd2 label to vdd_1v35_lp0 and as3722_sd5 label to vddio_1v8
- rename sd0 regulator from +VDD_CPU to +VDD_CPU_AP to match schematics
- rename sd6 regulator from +VDD_GPU to +VDD_GPU_AP to match schematics
- change polarity of GPIO K.01 from low to high for regulator +5V_VDD_TS_SW
- rename +3.3V_AVDD_HDMI regulator to +3.3V_AVDD_HDMI_AP_GATED
- make +3.3V_RUN regulator controlled by PMU_REGEN3
- add +3.3V_LP0 regulator (controlled by PMU_REGEN1), marking it as always
  on because it supplies the USB VBUS pins and we don't have a supply
  input for those yet

The version of host1x found on Tegra124 SoCs isn't compatible to earlier

[PATCH 5/7] ARM: tegra: Enable eDP for Venice2

[Thierry Reding]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Venice2 has a 12.9" (2560x1700) panel connected to the eDP output of the
Tegra124. The panel has an EDID to describe the video timings but needs
a few extra nodes to get the backlight to come up.

[PATCH 6/7] ARM: tegra: Add Tegra124 USB support

[Thierry Reding]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The USB controllers on Tegra124 are backwards-compatible with those
found on Tegra30.

These properties still all need the Tegra124 value in there too, just in
case there's a need to differentiate in the future. I can fix that up
when applying.

I've added those in v3 that I just sent out. I added Tegra124 values for
both the USB EHCI controllers as well as the PHY nodes.
