Subject: [PATCH v3 0/2] stm32 clocksource driver rework
Date: Wed, 20 Sep 2017 16:51:05 +0200	[thread overview]
Message-ID: <1505919067-28041-1-git-send-email-benjamin.gaignard@linaro.org> (raw)

version 3:
- fix comments done by Daniel
- use timer_of helper functions

version 2:
- fix uninitialized variable

These patch implements clocksource and clockevent by using only one hardware block.
Getting both clock source and events on the same hardware lead to change quite
a lot driver code.
It also limits usage of clocksource to 32 bits timers because 16 bits ones
aren't enough accurate.
Thanks to timer_fo helpers this series includes minor clean up in structures,
function prototypes and driver name.

Since 16 bits timers become useless it also removes them from stm32f4 and
stm32f7 devicetree.
