Subject[PATCH 0/4] clocksource/vt8500: Fix hangs in small delays
From: Roman Volkov <>

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:!topic/vt8500-wm8505-linux-kernel/vDMF_mDOb1k

Roman Volkov (4):
clocksource/vt8500: Use [read\write]l_relaxed()
clocksource/vt8500: Remove the 'loops' variable
clocksource/vt8500: Use MIN_OSCR_DELTA from PXA
clocksource/vt8500: Add register R/W functions
