cover 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

This series is based over v4.4-rc2-15-gcaa9c04 and depends on the following patch:

Please get rid of the extra line at the end of the file.. It will cause whitespace warnings when applying and will also cause issues applying other changes at the end of the file if they rely on the extra line. And check the whole series, thanks :) It will make my life a bit easier.

And the Subject line should start with "ARM: dts: ..." for the unified look.

PATCH 6/14 ARM: am437x: cm-t43: dts: add dual emac support

In reply to Nikita Kiryanov

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 12/14 ARM: sb-som: dts: introduce SB-SOM baseboard

Quoted 15 lines · Rob Herring
Quoted 5 lines · Nikita Kiryanov

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.

Yes, although they are currently undocumented. QS-600 should be CM-QS600 though.. Will fix in V2.

I would expect this to have a more specific.

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 is documented in Documentation/devicetree/bindings/display/panel/panel-dpi.txt You're correct about it being optional though.

PATCH 13/14 ARM: am437x: cm-t43: dts: add support for mmc1

In reply to Nikita Kiryanov

On SBC-T43 the mmc1 interface is connected to an SD-Card slot. Add the necessary muxing and configuration to the device tree.
