Subject[PATCH shawn/for-next v4 2/2] ARM: dts: imx: Add Y Soft IOTA Draco, Hydra and Ursa boards
Date
These are i.MX6S/DL based SBCs embedded in various Y Soft products.
All share the same board design but have slightly different HW
configuration.

Ursa
- i.MX6S SoC, 512MB RAM DDR3, 4GB eMMC, microSD
- parallel WVGA 7" LCD with touch panel
- 1x Eth (QCA8334 switch)
- USB OTG
- USB host (micro-B)

Draco
- i.MX6S SoC, 512MB RAM DDR3, 4GB eMMC, microSD
- parallel WVGA 7" LCD with touch panel
- 2x Eth (QCA8334 switch)
- USB OTG
- USB host (micro-B)
- RGB LED (I2C LP5562)
- 3.5mm audio jack + codec (LM49350)

Hydra
- i.MX6DL SoC, 2GB RAM DDR3, 4GB eMMC, microSD
- I2C OLED display, capacitive matrix keys
- 2x Eth (QCA8334 switch)
- USB OTG
- RGB LED (I2C LP5562)
- 3.5mm audio jack + codec (LM49350)
- HDMI
- miniPCIe slot

Changes since v3:
- Do not abbreviate regulator word in node names. (Shawn)
- Sort fixed regulator nodes alphabetically.
- Sort pmic regulator childe nodes alphabetically.
- Use newline between properties and child node in switch node. (Shawn)
- Sort i2c bus child nodes in order of unit-address. (Shawn)
- Rename PWM pinctl label to be consistent with node name. (Shawn)

Changes since v2:
- Remove cpus {/delete-node/ cpu@1;}; node from i.MX6Solo based board. (Fabio)
- Use "device_type = "memory";" in memory nodes. (Fabio)
- Use GPIO_ACTIVE_LOW for fec phy-reset-gpios. (Fabio)
- Use "-" in node names. (Rob)
- Remove label from led-controller node. (Rob)

Changes since v1:
- Enable HDMI on Hydra board.
- Move regulators to the root node and remove simple-bus property. (Rob)
- Remove reg and unit-address property from regulators. (Rob)
- Use correct names for led-controller and pmic node. (Rob)
- Use wakeup-source instead of deprecated enable-sdio-wakeup. (Shawn)
