[PATCH 00/14] Add support for sbc-t43

[Nikita Kiryanov]

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 05/14] ARM: am437x: cm-t43: dts: add NAND support

[Nikita Kiryanov]

One of the CompuLab cm-t43 configurations comes with on-board NAND flash as
primary storage. It is partitioned into kernel, dtb, and rootfs partitions.
Add it to the device tree.

[PATCH 06/14] ARM: am437x: cm-t43: dts: add dual emac support

[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

[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.

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.

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.
