[PATCH v5 0/6] ARM: Add Variscite DART-MX6 SoM and Carrier-board support

[Neil Armstrong]

This patchset adds support for the Variscite DART-MX6 SoM with :
- i.MX6 Quad or Dual Lite SoC
- 1Gb/2Gb LPDDR2
- 4-64 GB eMMC
- Camera Interface
- HDMI+CEC interface
- LVDS / DSI / Parallel RGB interfaces
- Ethernet RGMII interface
- On-SoM Wi-Fi/Bluetooth with WiLink wl1835 SDIO Module
- SD/MMC/SDIO interface
- USB Host + USB OTG interface
- I2C interfaces
- SPI interfaces
- PCI-Express 2.0 interface
- on-SoM Audio Codec with HP/Line-In interfaces + DMIC interface
- Digital Audio interface
- S/PDIF interface

And the Carrier-Board with the following :
- LVDS interface for the VLCD-CAP-GLD-LVDS 7" LCD 800 x 480 touch display
- HDMI Connector
- USB Host + USB OTG Connector
- 10/100/1000 Mbps Ethernet
- miniPCI-Express slot
- SD Card connector
- Audio Headphone/Line In jack connectors
- On-board DMIC
- CAN bus header
- SPI header
- Camera Interfaces header
- 4xButtons, 2xLeds
- OnBoard RTC with Coin Backup battery socket
- RS232 Header + USB-Serial debug port

First patch contains a missing pinmux define used by the SoM.
Last patch contains configs used by the SoM DT like SERDEV or WL18XX support.

PCIe, On-Board DMIC and Camera Interfaces are not handled yet.

Changes since v4 at [4]:
- Renamed coded label
- Updated gpio wakeup properties
- Removed useless panel blank lines
- Removed leading 0 in pmic node name address
- Changed last patch title to match imx defconfig name
- Fixed dtsi alphabetical ordering

Changes since v3 at [3]:
- minor pcie dt fix
- added tags

Changes since v2 at [2]:
- Added bindings acks
- fixed enable-active-high regulators property
- moved hdmi dd-i2c-bus to son dtsi
- fixed pinmux IOMUX value
- add pcie reset-gpio

Changes since v1 at [1]:
- Add lvds display vendor prefix and bindings
- fix all gpio phandle arguments with correct ACTIVE_XXX define
- drop pcie support
- drop custom operating points
- fix arm/pu/soc vin-supply instead of &cpu node override
- fix can pinmux value
- changed button node name
- add revied-by tags on first and last patches

[PATCH v5 4/6] ARM: dts: imx6qdl: Add Variscite DART-MX6 SoM support

[Neil Armstrong]

This patch adds support for the Variscite DART-MX6 SoM with :
- i.MX6 Quad or Dual Lite SoC
- 1Gb/2Gb LPDDR2
- 4-64 GB eMMC
- Camera Interface
- HDMI+CEC interface
- LVDS / DSI / Parallel RGB interfaces
- Ethernet RGMII interface
- On-SoM Wi-Fi/Bluetooth with WiLink wl1835 SDIO Module
- SD/MMC/SDIO interface
- USB Host + USB OTG interface
- I2C interfaces
- SPI interfaces
- PCI-Express 2.0 interface
- on-SoM Audio Codec with HP/Line-In interfaces + DMIC interface
- Digital Audio interface
- S/PDIF interface

Product website : http://www.variscite.com/products/system-on-module-som/cortex-a9/dart-mx6-cpu-freescale-imx6

Support is handled with a SoM-centric dtsi exporting the default interfaces
along the default pinmuxing to be enabled by the board dts file.

Only board-independent devices like WiFi, eMMC or PMIC are enabled in the dtsi.

[PATCH v5 5/6] ARM: dts: imx6q: Add Variscite DART-MX6 Carrier-board support

[Neil Armstrong]

This patch adds support for the i.MX6 Quad variant of the Variscite DART-MX6
SoM Carrier-Board.

This Carrier-Board has the following :
- LVDS interface for the VLCD-CAP-GLD-LVDS 7" LCD 800 x 480 touch display
- HDMI Connector
- USB Host + USB OTG Connector
- 10/100/1000 Mbps Ethernet
- miniPCI-Express slot
- SD Card connector
- Audio Headphone/Line In jack connectors
- On-board DMIC
- CAN bus header
- SPI header
- Camera Interfaces header
- 4xButtons, 2xLeds
- OnBoard RTC with Coin Backup battery socket
- RS232 Header + USB-Serial debug port

Product Page : http://www.variscite.com/products/evaluation-kits/dart-mx6-kits

The board support is done with all on-board and header interfaces enabled.
7" LVDS Touchscreen is enabled by default along HDMI output.
Audio interface is supported with the "simple-card" bindings.

PCIe slot, On-Board DMIC and Camera Interfaces are not handled yet.
