2016-08-24hwrng: omap3-rom - Remove obsoleted functionsPrasannaKumar Muralidharan1-8/+2
Remove omap3_rom_rng_data_present method as it was returning 1 always. Use .read callback instead of .data_read callback. This avoids use of obsolete callbacks. This patch is not tested with hardware as I don't have access to it. Signed-off-by: PrasannaKumar Muralidharan <prasannatsmkumar@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-11-23hwrng: omap3-rom - convert timer to delayed workAaro Koskinen1-6/+7
We cannot put the HW RNG to idle using a timer because we cannot disable clocks from atomic context. Use a delayed work instead. Fixes a warning with CONFIG_DEBUG_MUTEXES on Nokia N900 during boot.

2013-10-16hwrng: OMAP3 ROM Random Number Generator supportPali Rohár1-0/+141
This driver provides kernel-side support for the Random Number Generator hardware found on OMAP34xx processors. This driver comes from Maemo 2.6.28 kernel and was tested on Nokia RX-51. It is platform device because it needs board specific function for smc calls.
