[PATCH 0/3] arm64: dts: allwinner: h6: orangepi: Enable USB 2.0 and LEDs

[Chen-Yu Tsai]

Hi,

This small series enables USB 2.0 and LEDs on the Orange Pi Lite 2 and
Orange Pi One Plus. The two features are unrelated, but included in the
same series as the patch contexts overlap.

Patch one adds a fixed regulator to represent the board-wide 5V rail.
While not strictly necessary, this helps define the relationship between
regulators.

Patch two enables USB 2.0 host and OTG. Note that VBUS on both ports are
directly tied to the 5V rail, without any power switches or current
limiters.

Patch three add device nodes for the two LEDs. These LEDs are driven
directly by the GPIO pins, without a current limiting resistor. At the
default drive strength, the LEDs are quite bright.

Please have a look.
ChenYu

[PATCH 1/3] arm64: dts: allwinner: h6: orangepi: Add board-wide 5V regulator

[Chen-Yu Tsai]

The Orange Pi Lite 2 and Orange Pi One Plus share the same design for
their USB 2.0 ports. VBUS is directly tied to the board wide 5V rail,
which is also directly tied to the DC jack. There is no current limiting
in this design. This 5V rail also supplies the various inputs to the
PMIC.

This patch adds a board wide 5V regulator and sets it as the input to
the PMIC inputs.

[PATCH 2/3] arm64: dts: allwinner: h6: orangepi: Enable USB 2.0 host and OTG ports

[Chen-Yu Tsai]

The Orange Pi Lite 2 and Orange Pi One Plus share the same design for
their USB 2.0 ports. VBUS is directly tied to the board wide 5V rail,
which is also directly tied to the DC jack. There is no current limiting
in this design.

This patch enables all the USB 2.0 related device nodes, and sets the
VBUS regulator supplies and OTG ID detection GPIO.

[PATCH 3/3] arm64: dts: allwinner: h6: orangepi: Add device nodes for LEDs

[Chen-Yu Tsai]

The Orange Pi Lite 2 and Orange Pi One Plus both have two LEDs, one red
and one green. These are driven directly by GPIO lines in an active high
arrangement. The red LED is labeled "power", so it is set to be on by
default.

Note that the default drive current for the GPIO lines makes the LEDs
very bright.

Applied all three patches, thanks!
