From 50c49ef2ff4392aae2fd355663f2ba48d299faf2 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Mon, 3 Jan 2022 14:47:35 +0200 Subject: [PATCH] arm: dts: ls1028a-rdb: enable PCIe controllers from U-Boot dtsi Reuse the scheme implemented by the Kontron SL28 boards in commit d08011d7f9b4 ("arm: dts: ls1028a: disable the PCIe controller by default") and move the 'status = "okay"' lines for the PCIe controllers inside a separate U-Boot dtsi for the LS1028A-RDB board. This way, the existing Linux device tree can simply be dropped in.
