From: Ciprian Regus <redacted> The ADIN1140 is a single port 10BASE-T1S Ethernet controller that includes both the MAC and a PHY in the same package. Signed-off-by: Ciprian Regus <redacted> --- v3 changelog: - set adi,ad3306 as a fallback compatible. v2 changelog: - Reorder the compatible entries in the dt schema (ad3306, adin1140). - Removed "dt-bindings" from the commit title and message. - Updated the DT example to use IRQ_TYPE_LEVEL_LOW instead of IRQ_TYPE_EDGE_FALLING for the interrupt trigger condition. - "implements" -> "tries to implement" in the description. - Removed the MAINTAINERS entry, as it will be added in a later patch in the series. - Reordered as the first patch of the series --- .../devicetree/bindings/net/adi,adin1140.yaml | 71 ++++++++++++++++++++++ 1 file changed, 71 insertions(+)
