[PATCH 0/4] ARM: dts: sun8i: a33: Improvements for A33-OLinuXino

[Chen-Yu Tsai]

Hi,

Here are some cleanup and improvements for the A33-OLinuXino device
tree. The first two patches drop some unneeded bits. The latter two
enable peripherals that we now support.

[PATCH 1/4] ARM: dts: sun8i: a33: Drop GPIO pinmux settings for A33-OLinuXino

[Chen-Yu Tsai]

Normal GPIO usage does not need an additional pinmix setting. Exclusive
usage of the pin will be guaranteed by the driver.

Drop the extra pinmux settings.

[PATCH 2/4] ARM: dts: sun8i: a33: Drop sunxi-common-regulators.dtsi for A33-OLinuXino

[Chen-Yu Tsai]

None of the common regulators defined in sunxi-common-regulators.dtsi
are used for the A33-OLinuXino.

Drop the include.

[PATCH 3/4] ARM: dts: sun8i: a33: Enable PMIC power supplies on A33-OLinuXino

[Chen-Yu Tsai]

The A33-OLinuXino has a DC jack wired to the onboard PMIC's ACIN pins.
There is also a battery connector, wired to the PMIC's battery charger.

Enable the power supplies for both these components.

[PATCH 4/4] ARM: dts: sun8i: a33: Enable A33 internal audio codec on A33-OLinuXino

[Chen-Yu Tsai]

The A33-OLinuXino routes the SoC's headphone output to a headphone jack,
and the microphone input to a microphone jack. Power to the microphone
is provided by MBIAS.

This patch enables the various parts of the codec, and adds widgets and
routes for simple-card.

HBIAS is connected to the microphone jack as well, but in a manner that
is confusing and likely does not provide power. This part is left out
of this patch.
