[PATCH 04/16] clocksource: arm_arch_timer: move enums and defines to header file

Mark Rutland mark.rutland at arm.com
Wed Apr 19 12:44:21 EDT 2017


From: Fu Wei <fu.wei at linaro.org>

To support the arm_arch_timer via ACPI we need to share defines and enums
between the driver and the ACPI parser code.
So we split out the relevant defines and enums into arm_arch_timer.h.

No functional change.
