From 876816b2679f0bf2bdc5f9d04b00f58f419d88e2 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Sat, 16 Nov 2019 12:47:20 +0000 Subject: arm64: dts: rockchip: Improve nanopi4 PCIe Expand the power tree description with the 0V9 and 1V8 supplies to the RK3399 PCIe block. The NanoPis M4 and NEO4 just route 2 lanes to the user expansion pins, so there's not much more to say at the board level for them; NanoPC-T4 has a standard M.2 connector so we can at least claim the 3.3V supply to that too.
