[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:

[PATCH 01/14] ARM: am437x: cm-t43: dts: add basic support for sbc-t43

[Nikita Kiryanov]

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.

[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.

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.

Regards,

Tony
