[PATCH v3 3/4] mach-snapdragon: fixup power-domains
Aswin Murugan

Wed Jul 2 20:01:32 CEST 2025
RPMH power domain properties were initially removed from the
device tree due to the absence of driver support. Support for
SA8775P_MMCX and SA8775P_MMCX_AO has now been added in the RPMH
Power Domain Driver for the SA8775P platform.
Signed-off-by: Aswin Murugan <aswin.murugan at oss.qualcomm.com>

v3:
- Removed OF_LIVE_SA8775P config, since there is no SA8775P specific fixups are done
v2:
- Removed the power domain fixups, since the power domains are handled in qcom-rpmhpd driver
