Merge mainline to add prerequisite for ARM ux500 crypto support.
2012-04-27hwrng: omap - use devm_request_and_ioremapJulia Lawall
Using devm_request_and_ioremap is more concise. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2012-02-24ARM: OMAP: Remove plat/io.h by splitting it into mach/io.h and mach/hardware.hTony Lindgren
This is needed to minimize io.h so the SoC specific io.h for ARMs can removed. Note that minimal driver changes for DSS and RNG are needed to include cpu.h for SoC detection macros.

2011-06-30hwrng: omap - add missing clk_putJulia Lawall
Convert a return to a jump to an existing label that calls clk_put. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2; statement S; @@ e1 = clk_get@p1(...); ... when != e1 = e2 when != clk_put(e1) when any if (...) { ... when != clk_put(e1) when != if (...) { ... clk_put(e1) ... } * return@p3 ...; } else S // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Matt Mackall <mpm@selenic.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2011-02-16hwrng: omap - Convert release_resource to release_region/release_mem_regionJulia Lawall
Request_region should be used with release_region, not release_resource. The local variable mem, storing the result of request_mem_region, is dropped and instead the pointer res is stored in the drvdata field of the platform device. This information is retrieved in omap_rng_remove to release the region. The drvdata field is not used elsewhere. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ ( *x = request_region(...) | *x = request_mem_region(...) ) ... when != release_region(x) when != x = E * release_resource(x); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-09-24omap: rng: Use resource_size instead of manual calculationTobias Klauser
Use the resource_size function instead of manually calculating the resource size. This reduces the chance of introducing off-by-one-errors. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2009-06-02hwrng: omap - Move probe function to .devinit.textUwe Kleine-König
A pointer to omap_rng_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

2008-04-21[HWRNG] omap: Minor updatesDavid Brownell
Minor cleanups to the OMAP RNG: - Comment update re RNG status: * yes, it works on 16xx; "rngtest" is quite happy * it's fast enough that polling vs IRQ is a non-issue - Get rid of BUG_ON - Help GCC not be stupid about inlining (object code shrink) - Remove "sparse" warning - Cope with new hotplug rule requiring "platform:" modalias And make the file header match kernel conventions.

2008-01-11[HWRNG]: move status polling loop to data_present callbacksPatrick McHardy
Handle waiting for new random within the drivers themselves, this allows to use better suited timeouts for the individual rngs. Signed-off-by: Patrick McHardy <kaber@trash.net> Acked-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2007-10-19Convert files to UTF-8 and some cleanupsJan Engelhardt
* Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>

2006-08-06[PATCH] omap-rng build fixDavid Brownell
