Subject: [PATCH v2 0/7] NVIDIA Tegra clocksource improvements and clean up
Date: Sun, 5 May 2019 19:24:29 +0300 [thread overview]
Message-ID: <20190505162436.23125-1-digetx@gmail.com> (raw)
Hello,
This series primarily unifies the driver code across all Tegra SoC
generations. In a result the clocksources are allocated per-CPU on
older Tegra's and have a higher rating than the arch-timer, the newer
Tegra210 is getting support for microsecond clocksource / delay-timer
and the driver's code is getting much cleaner. Note that arch-timer usage
is discouraged on all Tegra's due to the time jitter caused by the CPU
frequency scaling.
The series was extensively tested on Tegra20 and Tegra30.
Changelog:
v2: Rebased on recent linux-next. Now all of #ifdef's are removed from the
code due to the recent patch that generalized persistent clocksource.
Couple other minor cosmetic changes.
Dmitry Osipenko (7):
clocksource/drivers/tegra: Support per-CPU timers on all Tegra's
clocksource/drivers/tegra: Unify timer code
clocksource/drivers/tegra: Reset hardware state on init
clocksource/drivers/tegra: Replace readl/writel with relaxed versions
clocksource/drivers/tegra: Release all IRQ's on request_irq() error
clocksource/drivers/tegra: Minor code clean up
clocksource/drivers/tegra: Use SPDX identifier
drivers/clocksource/timer-tegra20.c | 272 +++++++++++++---------------
