[PATCH] i.MX6: Karo: Update TX6 support

[PATCH] i.MX6: Karo: Update TX6 support

[Sascha Hauer]

This series has several improvements for the Karo TX6 module family.
With this we now support the i.MX6q variants and optionally eMMC
instead of only NAND. Also PMIC support for more variants is added.

[PATCH 1/7] ARM: i.MX: karo-tx6: Factor out a common tx6 dtsi file

[Sascha Hauer]

The stuff we currently have in the i.MX6q dts file can be reused for
the i.MX6dl variants, so factor out a common dtsi file.

[PATCH 2/7] ARM: i.MX: karo-tx6: Support eMMC board variants

[Sascha Hauer]

The TX6 board come with either NAND flash or eMMC as primary
storage medium. This adds support for the eMMC variants.
We can detect if we have NAND or eMMC by looking at the
bootsource which will be configured accordingly. This
way we can modify the device tree during runtime and do
not have to create a new image.

The i.MX6q variant is basically the same as the i.MX6dl variant, just
with another SoC and the usual i.MX6q/i.MX6dl adjustments.

[PATCH 4/7] ARM: i.MX: karo-tx6: Generalize 801x support

[Sascha Hauer]

The device tree for the 801x variant only contains displays. The
displays are not part of the SoM, but instead of the baseboard,
so they should be described in a baseboard dts. With this patch
we rather include the common tx6x dtsi file and drop 801x from
the barebox device tree names.

[PATCH 5/7] ARM: i.MX: karo-tx6: Setup other PMICs

[Sascha Hauer]

The TX6 boards come with 3 different PMIC variants from which we
currently only support the ltc3673. Detect the other two by i2c
address and set them up correctly. The code is based on the karo
U-Boot port.

[PATCH 6/7] ARM: i.MX: karo-tx6: disable power button

[Sascha Hauer]

The power button is not part of the CPU module and can be triggered
wrongly on other baseboards. Disable it since we do not need it
currently.

In the case of a successfull init this will return '1' and barebox then prints
an annoying error message like this:

Karo-tx6: PMIC setup failed with error -1
