Subject: [PATCH net-next v3 1/2] dt-bindings: mt76: support setting per-band MAC address
Date: Mon, 31 Jul 2023 23:23:16 +0100	[thread overview]
Message-ID: <d3130584b64309da28a04826100643ff6239f9ca.1690841657.git.daniel@makrotopia.org> (raw)

Introduce support for setting individual per-band MAC addresses using
NVMEM cells by adding a 'bands' object with enumerated child nodes
representing the 2.4 GHz, 5 GHz and 6 GHz bands.

In case it is defined, call of_get_mac_address for the per-band child
node, otherwise try with of_get_mac_address on the main device node and
fall back to a random address like it used to be.

While at it, add MAC address related properties also for the main node.

Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Changes since v2:
 * drop items list with only a single item

Changes since v1:
 * add dt-bindings
