Subject: [PATCH 0/7] clocksource: Add NVIDIA Tegra186 timers support
Date: Fri, 20 Mar 2020 14:34:45 +0100 [thread overview]
Message-ID: <20200320133452.3705040-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
This set of patches adds the device tree bindings and a simplified
driver for the timers found on Tegra186 and later SoCs. The driver
itself currently only implements a single watchdog, which in turn
relies on the counter provided by one of the timers. The timers
themselves are not used at the moment because the SoC also has an
architected timer and there's currently no use for the additional
timers provided by this hardware block.
I suggest that patches 1 & 2 go through the clocksource tree, while
I can carry the DTS changes in the Tegra tree for v5.8.
