Subject: [PATCH v6 1/2] dt: bindings: add new DT entry for ath11k PCI device support
Date: Thu, 25 Nov 2021 16:50:10 +0530 [thread overview]
Message-ID: <1637839211-1503-1-git-send-email-akolli@codeaurora.org> (raw)
Ath11k driver supports PCI devices such as QCN9074/QCA6390.
Ath11k firmware uses host DDR memory, DT entry is used to
reserve host DDR memory regions, send these memory base
addresses using DT entries.
Signed-off-by: Anilkumar Kolli <akolli@codeaurora.org>

V4:
- Fix dt_binding_check warnings (Rob)
V2:
- Use reserved-memory (Rob)
