From afa314d3a37797bd88c9a379a6fa150e6829fdf9 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Thu, 24 May 2018 17:11:57 +0200 Subject: [PATCH] rockchip: xhci: remove DTS parsing for PHY (which is unused) The xhci wrapper-driver for Rockchip searches the DTS to find its child node compatbile with 'rockchip,rk3399-usb3-phy' to retrieve the base-address of the PHY. However, this is currently broken (and always has been), returning NULL. However, the (wrongly) retrieved base-address is never used. We thus remove this code for now.
