Subject: [PATCH v2 3/8] dt-bindings: bluetooth: qcom: Add NVMEM BD address cell
Date: Thu, 07 May 2026 17:24:38 +0200 [thread overview]
Message-ID: <20260507-block-as-nvmem-v2-3-bf17edd5134e@oss.qualcomm.com> (raw)
In-Reply-To: <20260507-block-as-nvmem-v2-0-bf17edd5134e@oss.qualcomm.com>
Add support for an NVMEM cell provider for "local-bd-address",
allowing the Bluetooth stack to retrieve controller's BD address
from non-volatile storage such as an EEPROM or an eMMC partition.
Reviewed-by: Rob Herring (Arm) <robh@kernel.org>
