From cdf9010f6e173093d8dfeb4685063d78d35d7842 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Mon, 15 May 2023 12:59:49 +0300 Subject: [PATCH] phy: rockchip-inno-usb2: add initial support for rk3588 PHY Add initial support for the rk3588 PHY variant. The lookup for the host-port reg inside the struct now does a do {} while() instead of a while() {} in order to allow a first check for reg == 0.
