[PATCH v2 0/7] NVIDIA Tegra clocksource improvements and clean up

[Dmitry Osipenko]

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
