From c5c105b971b841dcf7292bcf37d8dcd63656e006 Mon Sep 17 00:00:00 2001 From: Tony Truong Date: Fri, 13 Nov 2020 09:30:05 -0800 Subject: [PATCH] ARM: dts: msm: update PCIe1 to support m.2 and generic EP on lahaina HDK PCIe1 on lahaina HDK has a m.2 interface which requires additional settings such as gpio to control the 3.3V, increased timeout for linking up, and having PCIe enumerate during its probe. Endpoints which connect to this slot will not manually trigger PCIe bus driver to do enumeration. Therefore update devicetree node to support PCIe1 on lahaina HDK.
