This patch series continues the modularization work described in the https://lore.kernel.org/linux-wireless/20250812-ath12k-mod-v1-0-8c9b0eb9335d@xxxxxxxxxxx ("wifi: ath12k: Ath12k modularization changes") series, which established the foundation for the Next Generation (NG) ath12k driver framework. That series introduced the foundational split of the original ath12k.ko into two distinct modules: a common module (ath12k.ko) and an architecture- specific module (ath12k_wifi7.ko) for Wi-Fi 7 devices as depicted below. +-----------------+ | | | ath12k.ko | | (common) | +---------------+ | | | | +-----------------+ | ath12k.ko | ===========> | | +------------------+ +---------------+ | | | ath12k_wifi7.ko | | (wifi7 family) | | | +------------------+ Building on that framework, this series focuses on modularizing the Data Path (DP) of the ath12k driver, allowing the common DP to be reused across different hardware architectures. The patches included here support the NG framework objective by reorganizing DP-specific files and the directory structure as outlined below.
