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.

- i.MX6 Quad or Dual Lite SoC
- 1Gb/2Gb LPDDR2
- 4-64 GB eMMC
- Camera Interface
- HDMI+CEC interface

- 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.

@ 2017-11-21 16:28 ` Neil Armstrong
0 siblings, 0 replies; 22+ messages in thread
From: Neil Armstrong @ 2017-11-21 16:28 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.

Don't the standard operating points described at imx6q.dtsi work on this board?
If not, please add a comment explaining why you need custom operating
points here.

Please avoid 0x80000000 and use the real IOMUX values instead.

It should, I will remove them, anyway it will conflict with the ones in imx6dl.dtsi.

* [PATCH 3/4] ARM: dts: imx6q: Add Variscite DART-MX6 Carrier-board support

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

@ 2017-11-21 16:28 ` Neil Armstrong

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

If you build this with W=1 it will give you warnings about using a
unit address without its corresponding reg field.
You could just drop the @x.
