[PATCH v4 1/5] dt-bindings: arm: fsl: Add Engicam i.Core MX8M Mini C.TOUCH 2.0

From: Jagan Teki <jagan@amarulasolutions.com>
Date: 2021-02-25 19:29:43 

i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.

C.TOUCH 2.0 is a general purpose carrier board with capacitive
touch interface support.

i.Core MX8M Mini needs to mount on top of this Carrier board for
creating complete i.Core MX8M Mini C.TOUCH 2.0 board.

Add bindings for it.

[PATCH v4 3/5] arm64: dts: imx8mm: Add Engicam i.Core MX8M Mini C.TOUCH 2.0

From: Jagan Teki <jagan@amarulasolutions.com>
Date: 2021-02-25 19:31:05 

Engicam C.TOUCH 2.0 is an EDIMM compliant general purpose Carrier
board.

Genaral features:
- Ethernet 10/100
- Wifi/BT
- USB Type A/OTG
- Audio Out
- CAN
- LVDS panel connector

i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.

i.Core MX8M Mini needs to mount on top of this Carrier board for
creating complete i.Core MX8M Mini C.TOUCH 2.0 board.

Changes for v4:
- don't create carrier board dtsi, move changes in final dts.
Changes for v3:
- don't maintain common nodes and include it, if no feature diff
Changes for v2:
- enabled fec1 node
- updated commit message
- dropped engicam from filename since it aligned with imx6 engicam
  dts files naming conventions.
- add i2c nodes
- fixed v1 comments

[PATCH v4 4/5] dt-bindings: arm: fsl: Add Engicam i.Core MX8M Mini EDIMM2.2 Starter Kit

From: Jagan Teki <jagan@amarulasolutions.com>
Date: 2021-02-25 19:31:26 

i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.

EDIMM2.2 Starter Kit is an EDIMM 2.2 Form Factor Capacitive Evaluation
Board from Engicam.

i.Core MX8M Mini needs to mount on top of this Evaluation board for
creating complete i.Core MX8M Mini EDIMM2.2 Starter Kit.

Add bindings for it.

i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.

i.Core MX8M Mini needs to mount on top of this Evaluation board for
creating complete i.Core MX8M Mini EDIMM2.2 Starter Kit.

PCIe, DSI, CSI nodes will add it into imx8mm-engicam-edimm2.2.dtsi once
Mainline Linux supported.

Changes for v4:
- don't create carrier board dtsi, move changes in final dts.
Changes for v3:
- don't maintain common nodes and include it, if no feature diff
Changes for v2:
- enabled fec1 node
- updated commit message
- dropped engicam from filename since it aligned with imx6 engicam
  dts files naming conventions.
- add i2c nodes
- fixed v1 comments
