Subject: [PATCH v15 01/13] clocksource/drivers/arm_arch_timer: Move enums and defines to header file
Date: Tue, 15 Nov 2016 21:13:23 +0800	[thread overview]
Message-ID: <1479215615-26950-2-git-send-email-fu.wei@linaro.org> (raw)
In-Reply-To: <1479215615-26950-1-git-send-email-fu.wei@linaro.org>

From: Fu Wei <fu.wei@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.

Split out the relevant defines and enums into arm_arch_timer.h, and
change "enum ppi_nr" to "enum arch_timer_ppi_nr" to avoid the potential
name clashes.
No functional change.
