[PATCH 0/2] dt-bindings: phy: ti,tcan104x-can: Document TI TCAN1051

[Maud Spierings via B4 Relay]

The Moduline Display mainboard contains 2 TI TCAN1051 CAN transceivers,
properly document these and add them to the devicetree.

Thank Peng Fan for inspiring this patch series.

[PATCH 1/2] dt-bindings: phy: ti,tcan104x-can: Document TI TCAN1051

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

TCAN1051-Q1 Automotive Fault Protected CAN Transceiver with CAN FD

It is pretty much identical to the TCAN1042, add the compatible with
fallback on the TCAN1042.

[PATCH 2/2] arm64: dts: freescale: imx8mp-moduline-display-106: Use phys to replace xceiver-supply

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

Fix the can tranceivers to actually use the new phy description instead
of the regulator tweak.
