Subject: [PATCH 1/6] ARM: meson: select HAVE_ARM_TWD and ARM_GLOBAL_TIMER
Date: Fri, 23 Nov 2018 20:53:06 +0100 [thread overview]
Message-ID: <20181123195311.4578-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20181123195311.4578-1-martin.blumenstingl@googlemail.com>
The 32-bit Meson SoCs use multiple Cortex-A9 (Meson8 and Meson8m2) or
Cortex-A5 (Meson8b) CPU cores. These come with the "ARM global timer"
and "Timer-Watchdog" (aka TWD, which provides both a per-cpu local timer
and watchdog).
Selecting ARM_GLOBAL_TIMER and HAVE_ARM_TWD allows us to add the timers
to the SoC.dtsi files.
