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.

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
