Subject: [PATCH v2 0/2] Add CPUCP mailbox support for Qualcomm Nord SoC
Date: Mon, 27 Apr 2026 08:52:34 +0800 [thread overview]
Message-ID: <20260427005236.230106-1-shengchao.guo@oss.qualcomm.com> (raw)
This series adds CPUCP mailbox controller support for Qualcomm Nord SoC.
The Nord CPUCP mailbox is functionally identical to the existing x1e80100
implementation, except it exposes 16 IPC channels instead of 3. Patch 1
adds the Nord compatible string to the DT binding. Patch 2 refactors
the channel count from a hardcoded compile-time constant into
a per-hardware configuration struct populated via the device tree
match data
Changes in v2:
- List Nord CPUCP as compatible with X1E80100 CPUCP in binding
- Drop the unnecessary change on @chans comment from the driver patch
- Link to v1: https://lore.kernel.org/all/20260420034932.1247344-1-shengchao.guo@oss.qualcomm.com/
