If I'm reading Olof's irc-comments from yesterday correctly, that is ri=
ght and=20
the 3 patches should go in together:

- "clocksource: arch_timer: Fix code to use physical timers
  when requested" fixes the use of physical timers in general
- "clocksource: arch_timer: Allow the device tree to specify uninitiali=
zed
  timer registers" allows this to be set from dt
- "ARM: dts: rk3288: add arm,cpu-registers-not-fw-configured" enables t=
his on
  rk3288
