*	hwrng: timeriomem - update to support more than one device	Alexander Clouter	2013-04-25	1	-5/+0
\| \| \| \| \| \| \| \| \|	timeriomem_rng only supports a single device instance. This patch enables multiple timeriomem_rng devices to coexist as well as adds some additional error checking.

*	hwrng: timeriomem - Use phys address rather than virt	Alexander Clouter	2009-03-27	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	There is no ioremap'ing or anything in timeriomem-rng.c as I foolishly used already remapped virtual addresses instead of passing the physical address to be polled. This patch fixes this flaw and lets developers do the Right Thing(tm). Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
*	hwrng: timeriomem - New driver	Alexander Clouter	2009-02-22	1	-0/+21
	Some hardware platforms, the TS-7800[1] is one for example, can supply the kernel with an entropy source, albeit a slow one for TS-7800 users, by just reading a particular IO address. This source must not be read above a certain rate otherwise the quality suffers. The driver is then hooked into by calling platform_device_(register\|add\|del) passing a structure similar to: ------ static struct timeriomem_rng_data ts78xx_ts_rng_data = { .address = (u32 __iomem) TS_RNG, .period = 1000000, / one second */ }; static struct platform_device ts78xx_ts_rng_device = { .name = "timeriomem_rng", .id = -1, .dev = { .platform_data = &ts78xx_ts_rng_data, }, .num_resources = 0, }; ------ [1] http://www.embeddedarm.com/products/board-detail.php?product=TS-7800 Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
