2.26.2
This adds support for the OMNIA Flex Concentrator product
from Kamstrup A/S. It's providing radio mesh communication
infrastructure for smart electricity meters.
Kamstrup OMNIA is a modular and scalable smart grid platform.

Changes since version 2:
- Found root cause of Ethernet PHY auto detect issue and created
a mdio patch series that resolves the issue.
https://lore.kernel.org/netdev/[email protected]/
- Ethernet PHY reset is using new MDIO bus reset.
- Ethernet PHY interrupt added.
- Removed SION from a few GPIOs used for Ethernet PHY.
Changes since version 1:
- Sorted labeling nodes.
- Sorted pinctrl entries.
- Removed deprecated fec phy reset properties.
- Added mdio phy reset properties.
- Disabled phy type auto detection and added note to commit message.
- Fixed two comment typos.

'make dtbs_check' reports the following issue:
compatible: ['kam,imx7d-flex-concentrator-mfg', 'kam,imx7d-flex-concentrator', 'fsl,imx7d'] is too long
I think dropping 'kam,imx7d-flex-concentrator' should fix it.
