From f1154884295a4bd00d6ebcaf01fa30141145903d Mon Sep 17 00:00:00 2001 From: Jonathan Bell Date: Wed, 20 Sep 2023 10:04:15 +0100 Subject: [PATCH] dt-bindings: PCI: brcmstb: add optional property - "brcm,tperst-clk-ms" This property can be used to delay deassertion of external fundamental reset, which may be useful for endpoints that require an extended time for internal setup to complete.
