Subject: [PATCH v3 00/15] Add support for Microchip LAN969x

This series adds support for the Microchip LAN969x switch SoC family.

Series is a bit long since after discussions in previous versions, it was
recommended[1][2] to add SoC specific compatibles for device nodes so it
includes the required bindings updates.

Signed-off-by: Robert Marko <robert.marko@...tura.hr>

Changes in v3:
* Pick Acked-by from Conor
* Drop HWMON binding as it was picked into hwmon already
* Document EV23X71A into AT91 binding
* Drop SparX-5 and AT91 bindings merge
* Apply remark from Conor on DMA binding regarding merging cases

Changes in v2:
* Change LAN969x wildcards to LAN9691 in patches
* Split SoC DTSI and evaluation board patches
* Add the suggested binding changes required for SoC specific compatibles
* Merge SparX-5 and AT91 bindings as suggested[3]
