Gregory Nutt	1f023fa31a	drivers/sensors: Fix more naming of configurations to be compliant for two more drivers. Still a few more to go.	2017-08-24 10:10:00 -06:00
Gregory Nutt	e9a5477506	Add an instance argument to the SPIDEV definitions.	2017-04-29 12:26:52 -06:00
Jussi Kivilinna	dffb8a67e3	Add entropy pool and strong random number generator ... Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output. Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.	2017-03-30 07:38:37 -06:00

Gregory Nutt	27bc1a2221	drivers/sensors: Change some *err() message to *info() messages if what was a *dbg() message does not indicate and error condition.	2016-06-11 18:21:49 -06:00
Gregory Nutt	a1469a3e95	Add CONFIG_DEBUG_ERROR. Change names of *dbg() * *err()	2016-06-11 15:50:49 -06:00
Gregory Nutt	3e7b2d617a	All drivers that use SPI must call SPI_LOCK and SPI_UNLOCK. This is not optional.	2016-05-26 14:56:10 -06:00
Gregory Nutt	7edf921c5e	Remove CONFIG_SPI_OWNBUS: Now it is not just a good idea, it is the law	2016-01-23 18:54:36 -06:00
Gregory Nutt	f6e49caba8	All SPI-based device drivers needs to call SPI_HWFEATURES() with zero in order to co-exist with drivers that use H/W features	2016-01-23 16:18:13 -06:00
