From 802bda5595ff79172652ede1bd0830b82f5dd596 Mon Sep 17 00:00:00 2001 From: Prasanthi Chellakumar Date: Fri, 25 May 2018 15:04:24 -0700 Subject: usb: host: ohci: fix sfr kernel warning in ohci-at91 driver The USB Host Controller driver 'ohci-at91.c' reads a Special Function Register - OHCI Interrupt Configuration Register (AT91_SFR_OHCIICR) for bits SUSPEND_A/B/C. These bits are defined in sama5d2 alone, so sfr register mapping is done with compatible string "atmel,sama5d2-sfr". This gives a kernel warning 'failed to find sfr node' with non sama5d2 cpus which is removed here, thus leaving it up to having a proper DTS.
