Subject: [PATCH 1/2] dt-bindings: net: wireless: ath11k: add new DT entry for board ID
Date: Tue, 21 Jun 2022 15:53:38 +0200	[thread overview]
Message-ID: <20220621135339.1269409-1-robimarko@gmail.com> (raw)

bus + qmi-chip-id + qmi-board-id and optionally the variant are currently
used for identifying the correct board data file.

This however is sometimes not enough as all of the IPQ8074 boards that I
have access to dont have the qmi-board-id properly fused and simply return
the default value of 0xFF.

So, to provide the correct qmi-board-id add a new DT property that allows
the qmi-board-id to be overridden from DTS in cases where its not set.
This is what vendors have been doing in the stock firmwares that were
shipped on boards I have.
