[PATCH v2 0/3] hw_random: timeriomem_rng: Migrate to new API and improve performance

[Rick Altherr]

AST2400 can generate 32-bits of random data every 1us.  Original driver
was limited to one 32-bit read every jiffie due to deprecated API and use
of timers.  Migrating to new hwrng API and switching to hrtimers
improves read performance of /dev/hwrng to 13Mb/s.

Changes in v2:
- Split API migration into separate patch
- Split type and variable renames into separate patch
- Split performance improvements into separate patch

Rick Altherr (3):
  hw_random: Migrate timeriomem_rng to new API
  hw_random: timeriomem_rng: Shorten verbose type and variable names
  hw_random: timeriomem_rng: Improve performance for sub-jiffie update
    periods
