[PATCH 3.16 217/294] Input: joystick - use get_cycles on ARMv8

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <broonie@xxxxxxxxxx>

commit a6b48699ae50ccce700506ced863ba1f5ce2af11 upstream.

As with ARM the ARMv8 architecture provides a cycle counter which can be
used to provide a high resolution time for the joystick driver and
silence the build warning that results from not having a precise timer
on ARMv8, making allmodconfig and allyesconfig quieter.
