clk_prepare()/clk_unprepare() must not be called within atomic context. This patch calls clk_prepare() once for all from atmel_sha_probe() and clk_unprepare() from atmel_sha_remove(). Then calls of clk_prepare_enable()/clk_disable_unprepare() were replaced by calls of clk_enable()/clk_disable().

2016-01-25crypto: caam - make write transactions bufferable on PPC platformsHoria Geant?
Previous change (see "Fixes" tag) to the MCFGR register clears AWCACHE[0] ("bufferable" AXI3 attribute) (which is "1" at POR). This makes all writes non-bufferable, causing a ~ 5% performance drop for PPC-based platforms. Rework previous change such that MCFGR[AWCACHE]=4'b0011 (bufferable + cacheable) for all platforms. Note: For ARM-based platforms, AWCACHE[0] is ignored by the interconnect IP.

2015-12-23crypto: atmel-aes - fix the counter overflow in CTR modeCyrille Pitchen
Depending on its hardware version, the AES IP provides either a 16 or a 32 bit counter.

2015-12-23crypto: atmel-aes - create sections to regroup functions by usageCyrille Pitchen
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.

2015-12-23crypto: atmel-aes - improve performances of data transferCyrille Pitchen
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.

2015-12-23crypto: atmel-aes - remove useless AES_FLAGS_DMA flagCyrille Pitchen

2015-12-23crypto: atmel-aes - reduce latency of DMA completionCyrille Pitchen

2015-12-23crypto: atmel-aes - rework crypto request completionCyrille Pitchen
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.

2015-12-23crypto: atmel-aes - make crypto request queue management more genericCyrille Pitchen
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).

2015-12-23crypto: atmel-aes - change atmel_aes_write_ctrl() signatureCyrille Pitchen
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.
