Subject: [PATCH v2 0/2] Add NMXC power domain for Nord SoC
Date: Wed, 26 Aug 2026 21:54:52 +0800 [thread overview]
Message-ID: <20260826135454.658615-1-shengchao.guo@oss.qualcomm.com> (raw)
The Nord CDSP subsystems do not take their memory rail from the shared
MX rail like all other Qualcomm SoCs, but from a dedicated NMXC RPMh
resource. Add the nmxc.lvl RPMh resource and register it in the Nord
power domain table.
Changes for v2:
- Drop remoteproc changes since "mx" of remoteproc is just the name of
memory rail input which can be wired up to NMXC power domain in DT
- Link to v1: https://lore.kernel.org/all/20260826102746.633076-1-shengchao.guo@oss.qualcomm.com/
