2013-09-02crypto: nx - fix limits to sg lists for AES-CBCMarcelo Cerri
This patch updates the nx-aes-cbc implementation to perform several hyper calls if needed in order to always respect the length limits for scatter/gather lists. Two different limits are considered: - "ibm,max-sg-len": maximum number of bytes of each scatter/gather list. - "ibm,max-sync-cop": - The total number of bytes that a scatter/gather list can hold. - The maximum number of elements that a scatter/gather list can have.

2013-08-21crypto: omap-sham - Enable Polling mode if DMA failsLokesh Vutla
For writing input buffer into DATA_IN register current driver has the following state machine: -> if input buffer < 9 : use fallback driver -> else if input buffer < block size : Copy input buffer into data_in regs -> else use dma transfer. In cases where requesting for DMA channels fails for some reason, or channel numbers are not provided in DT or platform data, probe also fails. Instead of returning from driver use cpu polling mode. In this mode processor polls on INPUT_READY bit and writes data into data_in regs when it equals 1. This operation is repeated until the length of message. Now the state machine looks like: -> if input buffer < 9 : use fallback driver -> else if input buffer < block size : Copy input buffer into data_in regs -> else if dma enabled: use dma transfer else use cpu polling mode.

2013-08-21crypto: omap-aes - Add support for cases of unaligned lengthsJoel Fernandes
For cases where offset/length of on any page of the input SG is not aligned by AES_BLOCK_SIZE, we copy all the pages from the input SG list into a contiguous buffer and prepare a single element SG list for this buffer with length as the total bytes to crypt. This is requried for cases such as when an SG list of 16 bytes total size contains 16 pages each containing 1 byte. DMA using the direct buffers of such instances is not possible. For this purpose, we first detect if the unaligned case and accordingly allocate enough number of pages to satisfy the request and prepare SG lists. We then copy data into the buffer, and copy data out of it on completion. Signed-off-by: Joel Fernandes <joelf@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2013-08-21crypto: omap-aes - PIO mode: Add IRQ handler and walk SGsJoel Fernandes
We add an IRQ handler that implements a state-machine for PIO-mode and data structures for walking the scatter-gather list. The IRQ handler is called in succession both when data is available to read or next data can be sent for processing. This process continues till the entire in/out SG lists have been walked. Once the SG-list has been completely walked, the IRQ handler schedules the done_task tasklet. Also add a useful macro that is used through out the IRQ code for a common pattern of calculating how much an SG list has been walked. This improves code readability and avoids checkpatch errors.

2013-08-21crypto: omap-aes - Simplify DMA usage by using direct SGsJoel Fernandes
In early version of this driver, assumptions were made such as DMA layer requires contiguous buffers etc. Due to this, new buffers were allocated, mapped and used for DMA. These assumptions are no longer true and DMAEngine scatter-gather DMA doesn't have such requirements. We simply the DMA operations by directly using the scatter-gather buffers provided by the crypto layer instead of creating our own. Lot of logic that handled DMA'ing only X number of bytes of the total, or as much as fitted into a 3rd party buffer is removed and is no longer required. Also, good performance improvement of atleast ~20% seen with encrypting a buffer size of 8K (1800 ops/sec vs 1400 ops/sec). Improvement will be higher for much larger blocks though such benchmarking is left as an exercise for the reader. Also DMA usage is much more simplified and coherent with rest of the code.

The most important limits in it are: - The total number of bytes that a scatter/gather list can hold. - The maximum number of elements that a scatter/gather list can have.

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input updates from Dmitry Torokhov: "First round of updates for the input subsystem. You will get a new touchsreen driver for Cypress 4th generation devices, a driver for a special controller implementing PS/2 protocol in OLPC devices, and a driver for power key for SiRFprimaII PWRC. HID and bcm5497 now support for the 2013 MacBook Air. EVIOCGKEY and the rest of evdev ioctls now flush events of matching type from the client's event queue so that clients can be sure any events received after issuing EVIOCG* ioctl are new events. And a host of cleanups and improvements in other drivers" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (87 commits) Input: cyttsp4 - kfree xfer_buf on error path in probe() Input: tps6507x-ts - select INPUT_POLLDEV Input: bcm5974 - add support for the 2013 MacBook Air HID: apple: Add support for the 2013 Macbook Air Input: cyttsp4 - leak on error path in probe() Input: cyttsp4 - silence NULL dereference warning Input: cyttsp4 - silence shift wrap warning Input: tps6507x-ts - convert to polled input device infrastructure ARM: davinci: da850-evm: remove vref from touchscreen platform data Input: cyttsp4 - SPI driver for Cypress TMA4XX touchscreen devices Input: cyttsp4 - I2C driver for Cypress TMA4XX touchscreen devices Input: cyttsp4 - add core driver for Cypress TMA4XX touchscreen devices Input: cyttsp - I2C driver split into two modules Input: add OLPC AP-SP driver Input: nspire-keypad - remove redundant dev_err call in nspire_keypad_probe() Input: tps6507x-ts - remove vref from platform data Input: tps6507x-ts - use bool for booleans Input: tps6507x-ts - remove bogus unreachable code Input: samsung-keypad - let device core setup the default pin configuration Input: wacom_i2c - implement hovering capability ...
