[PATCH v6 0/3] Add Phytec pbab01 audio support

[PATCH v6 0/3] Add Phytec pbab01 audio support

[Dmitry Lavnikevich]

This version of patchset contains following style changes since v5:
- nodes sorted in alphabetical order;
- pinctrl entries sorted alphabetically;
- new line inserted between nodes.

[PATCH v6 1/3] ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02

[Dmitry Lavnikevich]

Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.

This patch fixes i2c2, i2c3 pin configuration which caused messages:

imx6q-pinctrl 20e0000.iomuxc: no groups defined in /soc/aips-bus@02000000/iomuxc@020e0000/i2c2grp
