2014-11-17dmaengine: at_xdmac: fix missing spin_unlockLudovic Desroches1-0/+1
Lock taken when entering the function but unlock missing before it returns. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2014-11-17dmaengine: at_xdmac: fix a bug in transfer residue computationCyrille Pitchen1-1/+3
The total size of the transfer was wrong in at_xdmac_prep_slave_sg() resulting in bad computation of the transfer residue by at_xdmac_tx_status().

2014-11-17dmaengine: at_xdmac: fix software lockup at_xdmac_tx_status()Cyrille Pitchen1-5/+12
According to the Atmel eXtended DMA controller datasheet, requesting a DMA transfer flush for a channel is only revelant when this transfer is source peripheral synchronized. So we have to check this condition before requesting a channel flush by writing the channel bit into the Global channel SoftWare Flush (GSWF) register then waiting for flush to complete by monitoring the end of Flush Interrupt Status (FIS) bit in the Channel Interrupt Status (CIS) register. Indeed, for non source peripheral synchronized transfer, writing the channel bit into the GSWF register does nothing. Especially, the FIS bit is never set into the CIS register. The former code looped forever waiting for this bit to be set.

2014-11-17dmaengine: at_xdmac: prefer usage of readl/writel_relaxedLudovic Desroches2-5/+5
_relaxed version of readl and writel are not implemented on all architecture so COMPILE_TEST has to be removed in order to not cause some build failures. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

2014-11-17dmaengine: at_xdmac: fix usage of read, write wrappersVinod Koul1-4/+4
This driver uses read_relaxed and writel_relaxed to read, write to IO memory. the config defines COMPILE_TEST so gets compiled on different archs. This causes issue as few archs like x86 etc don't define it. So use readl/writel which is defined in all archs Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
