From 3da15f0b49a22743b6ed5756e4082287a384bc83 Mon Sep 17 00:00:00 2001 From: Manoj Sai Date: Fri, 17 Feb 2023 17:28:40 +0530 Subject: [PATCH] phy: rockchip-inno-usb2: Add USB2 PHY for rk3568 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit RK3568 has two USB 2.0 PHYs, and each PHY has two ports, the OTG port of PHY0 support OTG mode with charging detection function, they are similar to previous Rockchip SoCs. However, there are three different designs for RK3568 USB 2.0 PHY. 1. RK3568 uses independent USB GRF module for each USB 2.0 PHY. 2. RK3568 accesses the registers of USB 2.0 PHY IP directly by APB. 3. The two ports of USB 2.0 PHY share one interrupt. This patch only PHY1 with necessary attributes required to function USBPHY1 on U-Boot.
