Hi,
Changes in v3:
- Clubbed all the dt node into a single patch as suggested by Krzysztof.
- Removed the applied patch.
- Addressed some comments from Konrad and Dmitry.
Changes in v2:
- Added the CPUFreq support patch.
- Collected the Acked by tags.
- Addressed some minor comments from Konrad.
This series adds devicetree support for Qualcomm SDX75 platform and IDP
board. This series functionally depends on GCC and RPMh Clock support
series [1], and pinctrl support for SDX75 [2] which are under review.
With this current devicetree support, the IDP can boot into initramfsshell.

Thanks,
Rohit.

2.7.4
Add basic devicetree support for SDX75 platform and IDP board from
Qualcomm. The SDX75 platform features an ARM Cortex A55 CPU which forms
the Application Processor Sub System (APSS) along with standard Qualcomm
peripherals like GCC, TLMM, UART, QPIC, and BAM etc... Also, there
exists the networking parts such as IPA, MHI, PCIE-EP, EMAC, and Modem
etc..

You miss properties like level and unified. Maybye you tested it with
some old (half year ago) dtschema?
It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
