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 .../devicetree/bindings/rng/omap3_rom_rng.txt | 27 +++ arch/arm/boot/dts/omap3-n900.dts | 6 + arch/arm/mach-omap2/pdata-quirks.c | 14 +- drivers/char/hw_random/omap3-rom-rng.c | 168 +++++++++++------- 4 files changed, 139 insertions(+), 76 deletions(-) create mode 100644 Documentation/devicetree/bindings/rng/omap3_rom_rng.txt Reviewed-by: Tero Kristo Reviewed-by: Sebastian Reichel Tested-by: Aaro Koskinen
