From e2e37224e8b3a5194e4fc4797ef7309a78841673 Mon Sep 17 00:00:00 2001 From: Hector Martin Date: Fri, 16 Sep 2022 17:02:26 +0100 Subject: [PATCH] dt-bindings: net: bcm4329-fmac: Add Apple properties & chips MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This binding is currently used for SDIO devices, but these chips are also used as PCIe devices on DT platforms and may be represented in the DT. Re-use the existing binding and add chip compatibles used by Apple T2 and M1 platforms (the T2 ones are not known to be used in DT platforms, but we might as well document them). Then, add properties required for firmware selection and calibration on M1 machines.
