Subject: [PATCH 2/3] interconnect: qcom: Restrict drivers per ARM/ARM64
Date: Tue, 28 Apr 2026 19:32:38 +0200	[thread overview]
Message-ID: <20260428-interconnect-qcom-clean-arm64-v1-2-e6bc3f7832db@oss.qualcomm.com> (raw)
In-Reply-To: <20260428-interconnect-qcom-clean-arm64-v1-0-e6bc3f7832db@oss.qualcomm.com>

There is no point to allow selecting core SoC drivers like interconnects
for Qualcomm ARMv7 SoCs when building ARM64 kernel, and vice versa.

This makes kernel configuration more difficult as many do not remember
the Qualcomm SoCs model names/numbers and their properties like
architecture.  No features should be lost because:
1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.
