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.

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
