This patch calls clk_prepare() once for all from atmel_aes_probe() and clk_unprepare() from atmel_aes_remove().

* crypto: atmel-aes - fix the counter overflow in CTR modeCyrille Pitchen2015-12-231-2/+115
| | | | | | | | | | Depending on its hardware version, the AES IP provides either a 16 or a 32 bit counter. However the CTR mode expects the size of the counter to be the same as the size of the cipher block, ie 128 bits for AES. This patch detects and handles counter overflows.

* crypto: atmel-aes - create sections to regroup functions by usageCyrille Pitchen2015-12-231-102/+108
| | | | | | | | | | | | | | | | This patch only creates sections to regroup functions by usage. This will help to integrate the GCM support patch later by making the difference between shared/common and specific code. Hence current sections are: - Shared functions: common code which will be reused by the GCM support. - CPU transfer: handles transfers monitored by the CPU (PIO accesses). - DMA transfer: handles transfers monitored by the DMA controller. - AES async block ciphers: dedicated to the already supported block ciphers - Probe functions: used to register all crypto algorithms.

* crypto: atmel-aes - improve performances of data transferCyrille Pitchen2015-12-231-378/+386
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch totally reworks data transfer. 1 - DMA The new code now fully supports scatter-gather lists hence reducing the number of interrupts in some cases. Also buffer alignments are better managed to avoid useless copies. 2 - CPU The new code allows to use PIO accesses even when transferring more than one AES block, so futher patches could tune the DMA threshold (ATMEL_AES_DMA_THRESHOLD). Moreover, CPU transfers now have a chance to be processed synchronously, hence reducing the latency by avoiding context switches when possible (less interrupts to process, less scheduling of the 'done' task). Indeed the 'DATA READY' bit is polled only one time in the Interrupt Status Register before enabling then waiting for the associated interrupt. In some condition, this single poll is enough as the data have already been processed by the AES hardware and so are ready.

| | | | | | | | | | | | | This patch introduces a new callback 'resume' in the struct atmel_aes_dev. This callback is run to resume/complete the processing of the crypto request when woken up by I/O events such as AES interrupts or DMA completion.

* crypto: atmel-aes - make crypto request queue management more genericCyrille Pitchen2015-12-231-26/+49
| | | | | | | | | | | | | | | | This patch changes atmel_aes_handle_queue() to make it more generic. The function argument is now a pointer to struct crypto_async_request, which is the common base of struct ablkcipher_request and struct aead_request. Also this patch introduces struct atmel_aes_base_ctx which will be the common base of all the transformation contexts. Hence the very same queue will be used to manage both block cipher and AEAD requests (such as gcm and authenc implemented in further patches).

* crypto: atmel-aes - change atmel_aes_write_ctrl() signatureCyrille Pitchen2015-12-231-14/+10
| | | | | | | | | | | | | | | | This patch changes the signature of atmel_aes_write_ctrl() to make it more generic. This will be used by future patches when implementing new block cipher modes such as GCM. Especially atmel_aes_hw_init() is now called outside atmel_aes_write_ctrl(): this allows to call atmel_aes_write_ctrl() many times, still initializing the hardware only once. Indeed, the support of GCM will require to update the Mode Register and the IV when processing a single request.

* crypto: atmel-aes - sync the buf used in DMA or CPULeilei Zhao2015-04-081-4/+12
| | | | | | | | | | | | | | | | | | The input buffer and output buffer are mapped for DMA transfer in Atmel AES driver. But they are also be used by CPU when the requested crypt length is not bigger than the threshold value 16. The buffers will be cached in cache line when CPU accessed them. When DMA uses the buffers again, the memory can happened to be flushed by cache while DMA starts transfer. So using API dma_sync_single_for_device and dma_sync_single_for_cpu in DMA to ensure DMA coherence and CPU always access the correct value. This fix the issue that the encrypted result periodically goes wrong when doing performance test with OpenSSH.

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.

* crypto: drivers - remove cra_list initializationJussi Kivilinna2012-08-011-2/+0
| | | | | | | | | | | | | | | | | | | Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/drivers/'.
