[PATCH v2 0/5] arm64: dts: qcom: kaanapali: Enable DisplayPort

[Balaji Kalkonda]

This series adds DisplayPort support for the Qualcomm Kaanapali SoC
and enables it on the MTP board.

Kaanapali has a single DisplayPort controller based on the SM8750
generation DP block, routed through the combo USB/DP QMP PHY. The
series:

 - Documents the new "qcom,kaanapali-dp" compatible in the DP controller
   and Kaanapali MDSS bindings.
 - Adds the Kaanapali descriptor to the DP driver.
 - Describes the DisplayPort controller node in kaanapali.dtsi, including
   its OPP table, clocks, and power domain, and wires it to the DPU and
   the USB/DP QMP PHY.
 - Enables USB-C audio support on the MTP board (WCD939x USBSS Type-C mux)
   as a prerequisite for exercising DP alt mode over the same Type-C port.
 - Enables the DisplayPort controller on MTP and advertises the supported
   link frequencies for DisplayPort over USB-C.

Changes in v2:
- Updated the DP controller binding patch subject from "Add Kaanapali" to
  "Document Kaanapali" and rewrote its commit message to describe the
  standalone compatible and SoC-specific resource counts (Sashiko AI).
- Updated the Kaanapali DP node to use the MMCX power domain (Dmitry,
  Sashiko AI).
- Added the missing second DP stream support in the Kaanapali DP node
  (Dmitry).
- Expanded the Kaanapali DP node commit message to document USB/DP PHY
  mode switching for DisplayPort altmode (Dmitry).
- Extended the MTP USB headset and Type-C commit message to document the
  WCD9395 USBSS mux I2C bus frequency of 100 kHz (Dmitry, Konrad,
  Mukesh).
- Removed an unnecessary line break from the DP node clock parent list
  (Dmitry).
