[PATCH v2 0/2] Add DT files for sc7280 IDP2 board

[Rajendra Nayak]

v2:
* Added the google,piglin compatible for the IDP2 board
* Rebased on the recent pmic cleanups [1]
* Moved pmr735a_die_temp into idp dts

The IDP2 board based off sc7280 SoC is derived from the existing
IDP platform, but has some differences like
* on board Embedded controller and H1 secure microprocessor
* PMIC changes (some pmic functionality handled by EC)
* MDP/Display power grid changes
* USB configuration changes

To handle the differences, all common functionality is now moved to
sc7280-idp.dtsi, which is included in both sc7280-idp and sc7280-idp2
dts files.

Additional functionality differences in IDP2 as listed above will be
added by subsequent patches, this series just makes sure we have the
split done to handle the commonalities and differences.

[PATCH v2 1/2] dt-bindings: arm: qcom: Document qcom,sc7280-idp2 board

[Rajendra Nayak]

Document the qcom,sc7280-idp2 board based off sc7280 SoC,
The board is also known as piglin in the Chrome OS builds,
so document the google,piglin compatible as well.

[PATCH v2 2/2] arm64: dts: qcom: sc7280-idp: Add device tree files for IDP2

[Rajendra Nayak]

Move all the common device tree bits for both sc7280 IDPs into a
sc7280-idp.dtsi and create 2 different dts files (sc7280-idp.dts
and sc7280-idp2.dts) in order to manage differences across the
IDP SKU1 and SKU2 Boards.
PMR735A is present on IDP board only and is not present on IDP2.
