[PATCH v2 00/15] Tegra ARM32 device-tree improvements for 5.15

[PATCH v2 00/15] Tegra ARM32 device-tree improvements for 5.15

[Dmitry Osipenko]

This series:

  - adds SoC thermal sensor node
  - adds interrupt for LM90 to Ouya, AC100, Nexus 7 and A500 devices
  - fixes interrupt of LM90 sensor for all boards
  - removes bogus VBUS regulators from A500 device-tree
  - improves thermal zones of Nexus 7 and A500 devices based on previous
    discussion with Daniel Lezcano [1]

[1] https://lore.kernel.org/lkml/1abadc69-1dd1-5939-c089-37a84be4781b@linaro.org/

[PATCH v2 01/15] ARM: tegra: Add SoC thermal sensor to Tegra30 device-trees

[Dmitry Osipenko]

Add the on-chip SoC thermal sensor to Tegra30 device-trees. Now CPU
temperature reporting and thermal throttling is available on all Tegra30
devices universally.

The LM90 temperature sensor should use edge-triggered interrupt because
LM90 hardware doesn't deassert interrupt line until temperature is back
to normal state, which results in interrupt storm. Correct the interrupt

[PATCH v2 11/15] ARM: tegra: acer-a500: Remove bogus USB VBUS regulators

[Dmitry Osipenko]

The configuration of USB VBUS regulators was borrowed from downstream
kernel, which is incorrect because the corresponding GPIOs are connected
to PROX_EN (A501 3G model) and LED_EN pins in accordance to the board
schematics. USB works fine with both GPIOs being disabled, so remove the
bogus USB VBUS regulators. The USB VBUS of USB3 is supplied from the fixed
5v system regulator and device-mode USB1 doesn't have VBUS switches.

[PATCH v2 13/15] ARM: tegra: acer-a500: Use verbose variant of atmel,wakeup-method value

[Dmitry Osipenko]

The verbose variant of the atmel,wakeup-method value was lost when patch
that added the property was merged because it conflicted with other patch,
re-add it for consistency.

[PATCH v2 14/15] ARM: tegra: acer-a500: Improve thermal zones

[Dmitry Osipenko]

Use skin temperature for maintaining temperature that is suitable
specifically for A500. Add CPU thermal zone that protects silicon.
All these changes don't make a significant difference, but it is a
more correct definition of thermal zones.
