[PATCH 00/16] arm64: dts: qcom: Extend Shikra device tree with peripheral and subsystem support

[Komal Bajaj]

Extend Shikra DT with peripheral and subsystem support across all SoM
variants (CQ2390M, CQ2390S, IQ2390S) and their EVK boards.

The series adds:

- QUPv3 serial engine configuration
- cpufreq-hw node for hardware-assisted CPU frequency scaling
- DDR bandwidth monitor (BWMONv5) nodes with OPP tables for dynamic
  DDR frequency scaling
- EPSS L3 interconnect provider node for L3 cache frequency scaling
- CPU OPP tables to drive DDR and L3 scaling per frequency domain
- SMP2P nodes for CDSP, modem and LMCU inter-processor signalling
- Remoteproc PAS nodes for CDSP, LPAICP and MPSS subsystems
- TSENS instance with 14 thermal sensors and thermal zone definitions
- Bluetooth (WCN3988) node with board-specific regulator supplies on
  all three EVK variants
- WiFi node in the SoC DTSI with board-specific power supply and
  calibration variant selection on all three EVK variants

This series depends on:

Does it really make sense to split cpufreq_hw, EPSS and OPP tables into
three separate patches?

No, FastRPC is not applicable for LPAICP. FastRPC is primarily used for 
offloading audio, sensor, or other DSP-related workloads, and is not 
required here.

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.

No, it's not a part of the SoC. Move it to the board files.

The modern PMU support for the WCN39xx family is currently not available 
in hci qca driver, that is why we have defined the regulators directly 
within the Bluetooth node.

Thanks for pointing out. I see that pwrseq support for WCN39xx was 
indeed added in commit 9f168e4de5fd. I'll update the patches to use the 
modern PMU bindings.

[PATCH 15/16] arm64: dts: qcom: shikra: add WiFi node support

[Komal Bajaj]

From: Miaoqing Pan <miaoqing.pan@oss.qualcomm.com>

Introduce the WiFi hardware description in shikra.dtsi, including
register space, interrupts, IOMMU configuration and reserved memory.
The node is kept disabled by default and is intended to be enabled
by board-specific device trees.

[PATCH 16/16] arm64: dts: qcom: shikra: enable WiFi on EVK boards

[Komal Bajaj]

From: Miaoqing Pan <miaoqing.pan@oss.qualcomm.com>

Enable WiFi support on Shikra CQS, CQM and IQS EVK variants.

Provide board-specific WiFi configuration, including power supply
connections and calibration variant selection. The WiFi node is
enabled on each EVK according to the corresponding PMIC and board
design.

It makes me wonder... You've added DSPs in three patches, one per board,
but BT and WiFi go together. Where is the logiic?

Squash with the BT changes. Use the PMU-based bindings. Don't forget the
swctrl GPIO.

Why is it dummy? Is there no regulator on the board?

WCN3990 does not rely on the PMU module; it is managed directly by 
ath10k, so the swctrl GPIO is not needed. The details are described in 
qcom,ath10k.yaml.

WCN3950_3P3_CHAIN0 :is powered by on Board 3rd Party Buck which is always ON, VREG_SYS is always on once the device is powered up.

Then it's not a dummy. Please add a proper regulator describing the
node.
