The HAMOA-IOT-EVK is an evaluation platform for IoT products, composed of
the Hamoa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.
This change enables the following peripherals on the carrier board:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
- Bluetooth
- Graphic
- Audio

Only for usercase specific firmware requirement we need to add WiFi node. For this case we need to wait both HSP and HMT's usercase specific firmwares are available on UPSTREAM, otherwise loading fw will fail. So for now, we can skip adding the WiFi node. Once the use-case-specific firmware is ready in upstream, I can add the WiFi node separately for both HSP and HMT. >>>> >>>> Co-developed-by: Quill Qi <le.qi@oss.qualcomm.com> # Audio >>>> Signed-off-by: Quill Qi <le.qi@oss.qualcomm.com> >>>> Co-developed-by: Jie Zhang <quic_jiezh@quicinc.com> # Graphic >>>> Signed-off-by: Jie Zhang <quic_jiezh@quicinc.com> >>>> Co-developed-by: Shuai Zhang <quic_shuaz@quicinc.com> # Bluetooth >>>> Signed-off-by: Shuai Zhang <quic_shuaz@quicinc.com> >>>> Co-developed-by: Yongxing Mou <quic_yongmou@quicinc.com> # USB DisplayPorts >>>> Signed-off-by: Yongxing Mou <quic_yongmou@quicinc.com> >>>> Signed-off-by: Yijie Yang <yijie.yang@oss.qualcomm.com> >>>> --- >>>> arch/arm64/boot/dts/qcom/Makefile | 1 + >>>> arch/arm64/boot/dts/qcom/hamoa-iot-evk.dts | 1247 ++++++++++++++++++++++++++++ >>>> 2 files changed, 1248 insertions(+) >>>> >
