2018-01-18hwrng: imx-rngc - simplify the power management definitionsMartin Kaiser
Use the SIMPLE_DEV_PM_OPS() macro instead of populating a struct dev_pm_ops directly. The suspend and resume functions will now be used for both hibernation and suspend to ram. If power management is disabled, SIMPLE_DEV_PM_OPS() evaluates to nothing, The two functions won't be used and won't be included in the kernel. Mark them as __maybe_unused to clarify that this is intended behaviour. With these modifications in place, we don't need the #ifdefs for power management any more.

2018-01-18crypto: marvell/cesa - Fix DMA API misuseRobin Murphy
phys_to_dma() is an internal helper for certain DMA API implementations, and is not appropriate for drivers to use. It appears that what the CESA driver really wants to be using is dma_map_resource() - admittedly that didn't exist when the offending code was first merged, but it does now.

2018-01-18ASoC: bcm2835: fix hw_params error when device is in prepared stateMatthias Reichl
If bcm2835 is configured as bitclock master calling hw_params() after prepare() fails with EBUSY. This also makes it impossible to use bcm2835 in full duplex mode. The error is caused by the split clock setup: clk_set_rate is called in hw_params, clk_prepare_enable in prepare. As hw_params doesn't check if the clock was already enabled clk_set_rate fails with EBUSY. Fix this by moving clock startup from prepare to hw_params and let hw_params properly deal with an already set up or enabled clock.

2018-01-18spi: a3700: Add full-duplex supportMaxime Chevallier
The armada 3700 SPI controller has support for full-duplex transfers, but it can only be done without using the hardware FIFOs. A full duplex transfer is done by shifting 4 bytes at a time, or even one byte at a time for transfers less than 4 bytes long. While this method is perfectly suitable for small transfers, it is still slower than using the FIFOs. This commit implement full-duplex support, making sure that half-duplex transfers are still done using the FIFOs with the existing method. Some setup functions were moved around to make sure the controller is properly configured before beginning each transfer. This was tested on EspressoBin with a logical analyser, and a simple setup where MISO is connected on MOSI. Transfers were made from userspace using spidev and spi-pipe from the spi-tools project Signed-off-by: Maxime Chevallier <maxime.chevallier@smile.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
