Document the GPI DMA engine on Shikra platform.
It is fully compatible with the GPI DMA engine found on SM6350,
thus using qcom,sm6350-gpi-dma as fallback compatible.

From: Sayantan Chakraborty <sayantan.chakraborty@oss.qualcomm.com>
Add CPU-to-DDR BWMON nodes and their corresponding opp tables for
Shikra SoC. This is necessary to enable power management and optimize
system performance from the perspective of dynamically changing DDR
frequencies.

I think cqm-evk etc. could make more sense but I guess this
is already shipped, so might as well

Yes, it's already shipped, so we'd prefer to keep it as-is.

The shikra includes one TSENS instance, with a total of 14 thermal
sensors distributed across various locations on the SoC.
The TSENS max/reset threshold is configured to 120°C in the hardware.
Enable all TSENS instances, and define the thermal zones with a hot trip
at 110°C and critical trip at 115°C.

Enable Bluetooth and WiFi connectivity on Shikra CQM, CQS and IQS
EVK boards using the WCN3988 combo chip.
For Bluetooth, enable uart8 and add WCN3988 Bluetooth node with
board-specific regulator supplies across CQM, CQS and IQS Shikra
EVK boards.
For WiFi, introduce the wcn3990-wifi hardware node in shikra.dtsi
with register space, interrupts, IOMMU configuration and reserved
memory. The node is kept disabled by default and enabled per-board
with the appropriate PMIC supply connections and calibration variant
selection.

Split the SoC and board changes
Should most of the board-level changes go to evk.dtsi, since
they're almost identical across all boards? You can e.g. simply
override the supplies in the IQS EVK DTS

Sure, i will the changes.

For wcn3988-pmu node, I can move it to shikra-evk.dtsi and add the
supplies in the board DTS files. However, this approach will be
subjective to per node, as other nodes (such as sound) have
board-specific changes beyond just supplies.
