Subject: [PATCH 5/7] arm64: dts: rockchip: convert PCIe to use per-lane PHYs for rk3339
Date: Mon, 17 Jul 2017 15:38:40 +0800 [thread overview]
Message-ID: <1500277122-21835-1-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1500276982-208439-1-git-send-email-shawn.lin@rock-chips.com>
Convert all RK3399 platforms to use per-lane PHY model in
order to save more power by idling the unused lane(s).
