  To: shawnguo, kernel, fabio.estevam
  Cc: Neil Armstrong, linux-arm-kernel, linux-kernel

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.

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

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

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 v2 4/6] ARM: dts: imx6qdl: Add Variscite DART-MX6 SoM support
@ 2017-11-22 11:02   ` Neil Armstrong
  0 siblings, 0 replies; 32+ messages in thread
From: Neil Armstrong @ 2017-11-22 11:02 UTC (permalink / raw)
  To: linux-arm-kernel

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 v2 5/6] ARM: dts: imx6q: Add Variscite DART-MX6 Carrier-board support

  To: shawnguo, kernel, fabio.estevam
  Cc: Neil Armstrong, linux-arm-kernel, linux-kernel

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.

* [PATCH v2 5/6] ARM: dts: imx6q: Add Variscite DART-MX6 Carrier-board support
@ 2017-11-22 11:02   ` Neil Armstrong
  0 siblings, 0 replies; 32+ messages in thread

  To: linux-arm-kernel

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.

Is this really GPIO_ACTIVE_HIGH?

If so, then a 'enable-active-high' property would be needed.

No ddc-i2c-bus property?

No 0x80000000 please. Use the real IOMUX value here instead.

No 'reset-gpio' property?

Is this really GPIO_ACTIVE_HIGH?

If so, then a 'enable-active-high' property would be needed.

No ddc-i2c-bus property?

No 0x80000000 please. Use the real IOMUX value here instead.

No 'reset-gpio' property?

Yes, I saw it while reviewing the other patch.

Do different boards use different I2C ports for the HDMI EDID?

If not, then you could probably put it here instead.

Not at my knowledge, but it's typically something routed on the carrier board.

Anyway I can set it here.
