From 62b3c680cfdc1f60a9143a1e4aabff7473629157 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Mon, 9 Nov 2020 17:03:35 +0800 Subject: [PATCH 1/3] arm64: dts: socfpga: Use generic "ngpios" rather than "snps,nr-gpios" This is to remove similar errors as below: OF: /.../gpio-port@0: could not find phandle Commit 7569486d79ae ("gpio: dwapb: Add ngpios DT-property support") explained the reason of above errors well and added the generic "ngpios" property, let's use it.
