Subject: [PATCH 08/34] brcmfmac: of: Fetch Apple properties
Date: Mon, 27 Dec 2021 00:35:58 +0900 [thread overview]
Message-ID: <20211226153624.162281-9-marcan@marcan.st> (raw)
In-Reply-To: <20211226153624.162281-1-marcan@marcan.st>
On Apple ARM64 platforms, firmware selection requires two properties
that come from system firmware: the module-instance (aka "island", a
codename representing a given hardware platform) and the antenna-sku.
The module-instance is hard-coded in per-board DTS files, while the
antenna-sku is forwarded by our bootloader from the Apple Device Tree
into the FDT. Grab them from the DT so firmware selection can use
them.
The module-instance is used to construct a board_type by prepending it
with "apple,".
