Subject: [PATCH v7 0/6] qcom: Add support for IQ-9075-evk board

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'.
