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.

Add cpufreq-hw node to support cpufreq scaling on Qualcomm Shikra SoCs.
Also, add Epoch Subsystem (EPSS) L3 interconnect provider node and OPP
tables required to scale DDR and L3 per freq-domain on Shikra SoC.

From: Gaurav Kohli <gaurav.kohli@oss.qualcomm.com>
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.

The node is kept disabled by default and is intended to be enabled
by board-specific device trees.

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, enable per-board with the appropriate PMIC supply
connections and calibration variant selection.

Since the module is on the EVK board itself, push the enablement of
these nodes there too

WCN3988 is present on SoM. In next revision, I will move this node to
SoM DTSI, so there is no need to add a label here.

This is obvious from the patch itself. Don't repeat patch contents, say
something useful.

Is the WiFI/BT chip a part of common schematics or not? Why do you
define power supplies here, while the chip itself is defined in a common
file?

You're right. WCN3988 is integrated on SoM, and its regulator
dependencies are provided by SoM PMIC.
I'll move the supply definitions to SoM DTSI.

Add gpio-reserved-ranges property to the tlmm node for all three
Shikra EVK variants (CQM, CQS, IQS) to mark GPIOs used by the
SoC internally and not available for general use.

These are generally added to prevent non-secure access upon TLMM
probe, i.e. the board won't boot if some of them are not protected.
I assume the proposed set contains both ones that are _absolutely
forbidden_ for Linux to touch, but also ones that are dedicated to
some specific purpose that Linux _shouldn't_ touch.
Please add comments, like in glymur-crd.dtsi:
gpio-reserved-ranges = <4 4>, /* EC TZ Secure I3C */
<10 2>, /* OOB UART */
<44 4>; /* Security SPI (TPM) */
explaining what these pins are.
If any of them are boot-critical, squash this into the introductory
change
Konrad

Yes, some GPIOs are reserved for secure-world use and are therefore not
accessible from the non-secure world.
I will update the commit message accordingly.

Sure, will add this info.
Thanks
