[PATCH v3 01/10] 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 v3:
- make the two +1.35V_LP0 regulator names unique by adding the PMIC
  output as suffix
- mark +1.05V_RUN as not always on since it isn't used and to prevent
  it from being shorted to ground when PMU_REGEN3 is pulled low

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

[PATCH v3 03/10] ARM: tegra: Add Tegra124 host1x support

[Thierry Reding]

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

The version of host1x on Tegra124 is largely compatible with that on
earlier Tegra generations. Some of the registers have moved around or
expanded to allow for more capability, so a separate compatible string
is still required.

[Thierry Reding]

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

The SOR block on Tegra124 can be used standalone to drive LVDS panels or
used in conjunction with the DPAUX block to support eDP.

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.

The patch is fine, so I'll apply it, but note that the naming rule
applies to the node name only, since that's visible in the compiled DTB,
but not the label name, so this could have been left as:

		as3722: pmic@40

That would have avoided the rest of the diffs in this patch, and might
have been useful on a board with a bunch of different PMICs that need to
be differentiated between.

I've applied patches 1-9 to Tegra's for-3.15/dt branch, and squashed
patch 10 into Tegra's for-3.15/defconfig branch.
