[PATCH v8 0/4] qcom: Add support for IQ-9075-evk board
Posted by Wasim Nazir 3 months, 1 week ago
This series:

Add support for Qualcomm's iq9-evk board using QCS9075 SOC.

QCS9075 is compatible IoT-industrial grade variant of SA8775p SOC.
Unlike QCS9100, it doesn't have safety monitoring feature of
Safety-Island(SAIL) subsystem, which affects thermal management.

In QCS9100 SOC, the safety subsystem monitors all thermal sensors and
does corrective action for each subsystem based on sensor violation
to comply safety standards. But as QCS9075 is non-safe SOC it requires
conventional thermal mitigation for thermal management.
In this series thermal mitigation changes are not included as it needs
more discussion whether to include the change in DT or in drivers.

Below are detailed informations on IQ-9075-evk HW:
------------------------------------------------------
QCS9075 SOM is stacked on top of IQ-9075-evk board.
On top of IQ-9075-evk board additional mezzanine boards can be stacked
in future.
IQ-9075-evk is single board supporting these peripherals:
  - Storage: 2 × 128 GB UFS, micro-SD card, EEPROMs for MACs,
    eMMC on mezzanine card
  - Audio/Video, Camera & Display ports
  - Connectivity: RJ45 2.5GbE, WLAN/Bluetooth, CAN/CAN-FD
  - Sensors: IMU
  - PCIe ports
  - USB & UART ports

Currently basic features are enabled to support 'boot to shell'.

---
Changelog:

v8:
  - Squash UFS support[1] into initial board support patch.
  - Remove uart10 pinctrl settings from board, it is moved to sa8775p.dtsi.
  - Arrange ufs nodes in alphabetical order.
  - v7-link: [2]

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
