4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Muellner <christoph.muell...@theobroma-systems.com>
commit c1d91f86a1b4c9c05854d59c6a0abd5d0f75b849 upstream.
This patch fixes the wrong polarity setting for the PCIe host driver's
pre-reset pin for rk3399-puma-haikou. Without this patch link training
will most likely fail.
Fixes: 60fd9f72ce8a ("arm64: dts: rockchip: add Haikou baseboard with RK3399-Q7
SoM")
