Subject: [PATCH] riscv: dts: starfive: fml13v01: enable pcie1
Date: Fri,  7 Feb 2025 17:36:18 +0800	[thread overview]
Message-ID: <20250207093618.126636-1-sandie.cao@deepcomputing.io> (raw)

Starfive Soc common defines GPIO28 as pcie1 reset, GPIO21 as pcie1 wakeup;
But the FML13V01 board uses GPIO21 as pcie1 reset, GPIO28 as pcie1 wakeup;
redefine pcie1 gpio and enable pcie1 for pcie based Wi-Fi.
