[PATCH V2 06/14] ARM: dts: am437x: cm-t43: add dual emac support
CM-T43 comes with 2 ethernet ports connected to the cpsw subsystem, which
has 2 modes of operation: switch mode and dual emac mode.
Add the relevant muxing and set it up to work in dual emac mode by
default.

[PATCH V2 00/14] Add support for sbc-t43
This series adds support for CompuLab sbc-t43 single baseboard computer.
sbc-t43 is composed of cm-t43 (the TI am437x based core module), and sb-som
baseboard. The sbc-t43 features include:
CPU:Texas Instruments Sitara AM4379 ARM Cortex-A9, 1GHz, or
Texas Instruments Sitara AM4376 ARM Cortex-A9, 800MHz
RAM:128MB - 1GB, DDR3-800, 32-bit data bua
Storage:NAND flash, 128MB - 512MB, or eMMC flash, 4GB - 32GB
SPI-flash 2MB
Two 1000/100/10Mbps Ethernet ports
WiFi/Bluetooth/NFC
Audio codec
SD-Card slot, up to 3 USB ports
DVI/LCD connectors

[PATCH V2 12/14] ARM: dts: sb-som: introduce SB-SOM baseboard
CompuLab SB-SOM baseboard is a carrier board for multiple arm-based SoMs.
It currently supports (with minor adjustments to assembly) CM-T43, CM-T54,
and CM-QS600 modules. It is a building block in the SBC-T43 single board
computer, which consists of cm-t43 on top of sb-som-t43.

[PATCH V2 01/14] ARM: dts: am437x: cm-t43: add basic support for sbc-t43
Add basic support for SBC-T43: a CM-T43 based single board computer.
CM-T43 is an AM437x based System-on-Module designed to serve as a building
block in embedded applications. SBC-T43 is composed of CM-T43 module on
top of the SB-SOM-T43 baseboard.
Basic support includes UART, GPIO, and I2C.

SB-SOM supports multiple modules. This device tree aggregates what is
common to all possible module-baseboard combinations, which is why the
compatible string is generic.

It currently supports (with minor adjustments to assembly) CM-T43, CM-T54,
and CM-QS600 modules. It is a building block in the SBC-T43 single board
computer, which consists of cm-t43 on top of sb-som-t43.

Re: [PATCH v7 0/6] wlcore: add device-tree support
