[PATCH 1/3] ARM: imx7d: add enet2 clk sel

[PATCH 1/3] ARM: imx7d: add enet2 clk sel

[Steffen Trumtrar]

Add clock source init for the second ethernet port.
This changes the clock direction and clock selection in a way that the
ethernet phy reference clock is routed as an output.

I know, that this is not a "good solution", but I don't know how we can
handle this in a better way. Open for suggestions.

[PATCH 3/3] ARM: imx7: add support for iotmaxx GW4100

[Steffen Trumtrar]

The GW4100 will be an i.MX7D based board from IoTMaxx.
The support is almost complete apart from the pmic setup which currently
can not be used because of a hardware bug. This can and will be changed
once it is fixed in hardware.
