Subject: [PATCH v6 0/6] arm64: dts: qcom: enable Bluetooth and WLAN on
 sc8280xp and sm8450 boards

This series previously only concerned sc8280xp but while enabling
WLAN/BT on sm8450 I noticed some more changes will be required so I
folded the latter into this series and updated the sc8280xp CRD and X13
patches.

==

This models the WLAN and Bluetooth modules on several boards using the
WCN6855 module.

The wcn6855 (also known as qca6490) is a bit different from the qca6390
so modify the power sequencing driver to support it with separate device
match data.

For the sc8280xp-crd and sm8450-hdk we add the PMU, wifi and bluetooth
nodes with the correctly modelled wiring between them. For the X13s, we
rework existing nodes so that they align with the new DT bindings
contract.

On sm8450-hdk we require some additional toggling of the XO-CLK signal
so add that to the driver as well and update the bindings.

Changes in v6:
- add the xo-clk signal handling to the pwrseq-qcom-wcn driver
- add a patch enabling wifi and bluetooth on sm8450-hdk
- add missing supplies to the PMUs on sc8280xp boards
- Link to v5: https://lore.kernel.org/all/20241008102545.40003-1-brgl@bgdev.pl/

Changes in v5:
- put vreg_s10b under the "B" PMIC on the CRD instead of modeling it as a
  fixed regulator
- order pinctrl nodes alphabetically
- restore the drive-strength property for all pins to what bootfw sets it to
- disable bias on wlan-en pin on the CRD
- remove stray newline
- add the swctrl pins to the PMU node

Changes in v4:
- bind bluetooth pins on X13s in patch 3/3
- only drop the regulator-always-on properties for vreg_s11b and vreg_s12b
  and fold this change into patch 3/3

Changes in v3:
- move adding the bt-enable-gpios to the PMU on the CRD to patch 2/4
- add a patch removing the regulator-always-on property from regulators
  on X13s that no longer need it

Changes in v2:
- fix commit message in patch 1/3
- drop drive-strength from the wlan enable pin function
- drop the calibration variant property from the wifi node of the CRD
