2014-03-10crypt: bfin_crc - Remove useless SSYNC instruction and cache flush to DMA ↵Sonic Zhang1-34/+11
coherent memory 1) SSYNC instruction is blackfin specific and takes no effect in this driver. 2) DMA descriptor and SG middle buffer are in DMA coherent memory. No need to flush. 3) Turn kzalloc, ioremap and request_irq into managed device APIs respectively.

2013-01-20crypto: bfin_crc - reposition free_irq to avoid access to invalid dataJulia Lawall1-3/+3
The data referenced by an interrupt handler should not be freed before the interrupt is ended. The handler is bfin_crypto_crc_handler. It may refer to crc->regs, which is released by the iounmap. Furthermore, the second argument to all calls to free_irq is incorrect. It should be the same as the last argument of request_irq, which is crc, rather than crc->dev. The semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @fn exists@ expression list es; expression a,b; identifier f; @@ if (...) { ... when any free_irq(a,b); ... when any f(es); ... when any return ...; } @@ expression list fn.es; expression fn.a,fn.b; identifier fn.f; @@ *f(es); ... when any *free_irq(a,b); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-06-12crypto: bfin_crc - CRC hardware driver for BF60x family processors.Sonic Zhang1-0/+780
The CRC peripheral is a hardware block used to compute the CRC of the block of data. This is based on a CRC32 engine which computes the CRC value of 32b data words presented to it. For data words of < 32b in size, this driver pack 0 automatically into 32b data units. This driver implements the async hash crypto framework API.
