Subject: [PATCH v4 00/13] Modem support for MSM8226

This series adds support for modem remoteproc found on MSM8226.
It also adds needed device tree nodes and enables modem used for
location service on matisse-wifi.

Also bam-dmux node is added for mobile data which is used on
3G/4G-enabled devices.

Changes in v4:
- Drop mx from .proxy_pd_names for msm8974 as it's always a regulator
  @Stephan: Please check that one also since I still picked up your R-b
- Move q6v5_external_bhs_enable to just after regulator enable and
  _disable to just before regulator disable, instead of them being in
  _probe and _remove (Stephan)
- Pick up tags
- Link to v3: https://lore.kernel.org/r/20250127-msm8226-modem-v3-0-67e968787eef@lucaweiss.eu

Changes in v3:
- Include dt-bindings & driver patch for MSM8926 modem which is slightly
  different
- Include patch to add msm8926.dtsi with modified modem
- Include patch to enable modem on MSM8926 HTC memul
- In single-pd driver patch modify if conditions to only trigger for
  8226, even for misconfigured dts (Stephan)
- Don't /delete-node/ & /delete-property/ for no-modem smartwatches,
  just make mpss_region & mba_region be disabled by default (Stephan)
- Configure matisselts mss-supply correctly (Stephan)
- Pick up tags
- Link to v2: https://lore.kernel.org/r/20250126-msm8226-modem-v2-0-e88d76d6daff@lucaweiss.eu
