Subject: [PATCHv2 0/7] Non-urgent fixes and improvments for omap3-rom-rng

Hi all,

Here are fixes and improvments for omap3-rom-rng that's been broken for
a while.

The first four patches get it working, and then the last two patches add
support for runtime PM.

I did not add Sebastian's acks from v1 set as many of the patches
changed. Please review again :)

Regards,

Tony

Changes since v1:
- Use clk_prepare_enable() as pointed out by Sebastian
- Simplify runtime PM changes patch
- Add a new patch for devm changes as suggested by Sebastian


Tony Lindgren (7):
  ARM: OMAP2+: Check omap3-rom-rng for GP device instead of HS device
  hwrng: omap3-rom - Fix missing clock by probing with device tree
  hwrng: omap3-rom - Call clk_disable_unprepare() on exit only if not
    idled
  hwrng: omap3-rom - Initialize default quality to get data
  hwrng: omap3-rom - Update to use standard driver data
  hwrng: omap3-rom - Use runtime PM instead of custom functions
  hwrng: omap3-rom - Use devm hwrng and runtime PM
