From 147a70ceda533f4b4c8fab17efa97efe11018f09 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Thu, 9 Mar 2017 16:47:06 +0000 Subject: [PATCH] arm64: sysreg: add physical timer registers This patch adds sysreg definitions for system registers used to control the architected physical timer. Subsequent patches will make use of these definitions. The encodings were taken from ARM DDI 0487A.k_iss10775, Table C5-6.
