Subject[PATCH v3 0/3] clocksource/vt8500: Fix hangs in small delays
Date
From: Roman Volkov <rvolkov@v1ros.org>

vt8500 hangs in nanosleep() function, starting from commit
c6eb3f70d4482806dc2d3e1e3c7736f497b1d418, making the system unusable.
Per investigation, looks like set_next_event() now receives too small
delta and fails with -ETIME.

Google group discussion:
https://groups.google.com/forum/#!topic/vt8500-wm8505-linux-kernel/vDMF_mDOb1k

v2:
Address comments by Alexey Charkov. Merge patches to get less amount of
changes (three patches instead of four).

v3:
Address comments by Thomas Gleixner. Edit the changelog.

Tested on my WM8650, no issues in three days uptime.

Roman Volkov (3):
clocksource/vt8500: Use MIN_OSCR_DELTA from PXA
clocksource/vt8500: Remove the 'loops' variable
clocksource/vt8500: Add register R/W functions
