This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions, under or above your Signed-off-by tag. Tag is "received", when provided in a message replied to you on the mailing list. Tools like b4 can help here. However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for tags received on the version they apply.

https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed. Best regards,
Krzysztof

Oops, I forgot to add Conor's ack...

IIRC, the b4 can only help on the latest version. If I missed the ack in v3, the ack tag will be lost. So how to handle this case? repost or Conor gave an ack to v3 again?

The Sipeed Longan SoM 3H is a system on module based on the Allwinner H618 SoC. The SoM features:

- Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU
- 2/4 GiB LPDDR4 DRAM SoMs
- AXP313a PMIC
- eMMC

The Sipeed Longan PI 3H is a development board based on the above SoM. The board features:
- Longan SoM 3H
- Raspberry-Pi-1 compatible GPIO header
- 2 USB 2.0 host port
- 1 USB 2.0 type C port (power supply + OTG)
- MicroSD slot
- 1Gbps Ethernet port (via RTL8211 PHY)
- HDMI port
- WiFi/BT chip

Add the devicetree file describing the currently supported features, namely PMIC, LEDs, UART, SD card, eMMC, USB and Ethernet.

Since v2:
- collect Reviewed-by tag
- add vin-supply property to reg_vcc3v3
- fix reg_vcc3v3 voltage value
- remove "interrupt-parent" and "interrupts" properties from axp313 node

Since v1:
- Use const rather than enum for "sipeed,longan-pi-3h" dt-binding
- remove dts-v1, model and compatible from SoM dtsi
- add interrupt related properties to axp313 dt node
- use "vcc-1v8-pll" and "vcc-3v3-io" as regulator name
- add dt node for board's discrete 5V->3.3V regulator and use it for eth\tfcard 3.3v supply
- add usb2_vbus-supply property
