Subject: [PATCH v1 0/6] Consolidate and improve NVIDIA Tegra CPUIDLE driver(s)
Date: Mon,  8 Jul 2019 02:38:03 +0300	[thread overview]
Message-ID: <20190707233809.14400-1-digetx@gmail.com> (raw)

Hello,

I was spending quite some time recently trying to hunt down CPU-suspend
bug on Tegra30 SoC and in the end it was nailed. During that time I
realized that the CPU Idle drivers could get some polish and gain new
features, thus that's what this series does:

  1. Unifies Tegra20/30/114 drivers into a single driver and moves it out
     into common drivers/cpuidle/ directory.

  2. Enables CPU cluster power-down idling state on Tegra30.

  3. Removes CPUIDLE_FLAG_TIMER_STOP from all of the states since that
     flag is not relevant anymore.

In the end there is a quite nice clean up of the Terga CPUIDLE driver(s)
and of the Tegra's arch code in general. Please review, thanks!
