From b1022566e7429844b954c01cdddc63212af1095c Mon Sep 17 00:00:00 2001 From: Yifeng Zhao Date: Fri, 9 Oct 2020 14:39:29 +0800 Subject: [PATCH 430/478] 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.
