Subject: [PATCH v2 0/2] Support single-PD in wcnss driver

Both MSM8974 and MSM8226 only model CX as power domain, leaving MX & PX
as regulators. Add some patches to support this use case.

Signed-off-by: Luca Weiss <luca@...aweiss.eu>

Changes in v2:
- Narrow down dt-schema to only allow one of these three options:
    - cx regulator + mx regulator (still deprecated)
    - cx pd + mx regulator
    - cx pd + mx pd
- Link to v1: https://lore.kernel.org/r/20250129-wcnss-singlepd-v1-0-b01a6ba0b1bd@lucaweiss.eu
