3d11f8ae36 imx6: fix device-tree mac address assignment for ventana sky2/eth1
Some Ventana boards have a Marvell sky2 GigE controller as eth1 however
assigning the mac address through device-tree is difficult because the
PCI slot can move around depending on board configuration and slot population.

To work around this we add a patch to the sky2 driver to allow accessing its
mac address via a device-tree alias.

2578f0183c imx6: add i2c retries for Ventana /dev/i2c-0
On Ventana boards the Gateworks System Controller is the only device on I2C1
(/dev/i2c-0) and it can NAK transfers if it is busy in an ADC loop. Because
this is a multi-function device with several slave addresses it is best to
add retries at the controller level instead of within each slave driver. This
adds a patch that adds 3 retries for i2c transactions only for Ventana boards
and only for I2C1

158b5b4231 imx6: imx: thermal: use CPU temperature grade info for thresholds
This is a backport of a2291badc355d58ead5c19ae0609468947416040 from thermal-soc
accepted upstream.

The IMX6Q/IMX6DL SoC's have a 2-bit temperature grade stored in OTP. Instead
of assuming 85C for passive cooling threshold and 100C for critical base
these thresholds off the thermal gade max CPU temperature:
 - passive threshold: max - 10C
 - critical threshold: max - 5C
