Add DTSI of Variscite VAR-SOM-MX8MM System on Module in a basic version,
delivered with Variscite Symphony Evaluation kit. This version comes
with:
- 2 GB of RAM,
- 16 GB eMMC,
- Gigabit Ethernet PHY,
- 802.11 ac/a/b/g/n WiFi with 4.2 Bluetooth (Cypress CYW43353),
- CAN bus,
- Audio codec (not yet configured in DTSI).

Changes since v2:
1. Remove fsl,spi-num-chipselects,
2. Remove can node (not yet in mainline),
3. Use phy properties instead of deprecated phy-reset-xxx,
4. Remove orphaned pinctrl-names,
5. Use lowercase regulator names to match schema,
6. Use more specific regulator node names.
Changes since v1:
1. None

Cc: Krzysztof Kozlowski
Add DTSI of Variscite VAR-SOM-MX8MM System on Module in a basic version,
delivered with Variscite Symphony Evaluation kit. This version comes
with:
- 2 GB of RAM,
- 16 GB eMMC,
- Gigabit Ethernet PHY,
- 802.11 ac/a/b/g/n WiFi with 4.2 Bluetooth (Cypress CYW43353),
- CAN bus,
- Audio codec (not yet configured in DTSI).
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v2:
1. Remove fsl,spi-num-chipselects,
2. Remove can node (not yet in mainline),
3. Use phy properties instead of deprecated phy-reset-xxx,
4. Remove orphaned pinctrl-names,
5. Use lowercase regulator names to match schema,
6. Use more specific regulator node names.
Changes since v1:
1. None

Add a DTS for Variscite Symphony evaluation kit with VAR-SOM-MX8MM
System on Module.
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v2:
1. Use 'led' as node name to be generic,
2. Remove orphaned pinctrl-names.
3. Use more specific regulator node names.
Changes since v1:
1. Remove duplicated "leds" node,
2. Fix heartbeat to active low,
3. Add nxp,ptn5150 extcon.
