From d8242e6a71bac37b6cde52c0add533615eef8c5e Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Tue, 26 May 2020 17:21:15 +0800 Subject: [PATCH] MIPS: DTS: Loongson64: Add PCI Controller Node Add PCI Host controller node for Loongson64 with RS780E PCH dts. Note that PCI interrupts are probed via legacy way, as different machine have different interrupt arrangement, we can't cover all of them in dt.
