From 7160820d742a16313f7802e33c2956c19548e488 Mon Sep 17 00:00:00 2001 From: Yifeng Zhao Date: Tue, 8 Feb 2022 17:13:25 +0800 Subject: phy: rockchip: add naneng combo phy for RK3568 This patch implements a combo phy driver for Rockchip SoCs with NaNeng IP block. This phy can be used as pcie-phy, usb3-phy, sata-phy or sgmii-phy.
