Subject: [PATCH v1 6/6] cpuidle: tegra: Remove CPUIDLE_FLAG_TIMER_STOP from all states
Date: Mon, 8 Jul 2019 02:38:09 +0300 [thread overview]
Message-ID: <20190707233809.14400-7-digetx@gmail.com> (raw)
In-Reply-To: <20190707233809.14400-1-digetx@gmail.com>
The Tegra's clocksource driver got some rework recently and now the
internal/local CPU timers usage is discouraged on Tegra20/30 SoCs in
a favor of the platform-specific timers that are assigned as per-CPU
clocksources because they do not suffer from the CPU-freq changes and
are always-ON during of CPU-idling. That happened in the commit
f6d50ec5f85c ("clocksource/drivers/tegra: Support per-CPU timers on all
Tegra's"). The Tegra's clocksource driver is the essential arch-driver
that is guaranteed to always present on all Tegra SoCs up to Tegra124.
