crypto: caam - fix RNG deinstantiation error checking

2017-04-05T13:20:17Z

RNG instantiation was previously fixed by commit 62743a4145bb9 ("crypto: caam - fix RNG init descriptor ret. code checking") while deinstantiation was not addressed. Since the descriptors used are similar, in the sense that they both end with a JUMP HALT command, checking for errors should be similar too, i.e. status code 7000_0000h should be considered successful.

crypto: caam - fix invalid dereference in caam_rsa_init_tfm()

2017-04-05T13:20:16Z

In case caam_jr_alloc() fails, ctx->dev carries the error code, thus accessing it with dev_err() is incorrect. Cc: # 4.8+ Fixes: 8c419778ab57e ("crypto: caam - add support for RSA algorithm") Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam - fix JR platform device subsequent (re)creations

2017-04-05T13:20:15Z

The way Job Ring platform devices are created and released does not allow for multiple create-release cycles. JR0 Platform device creation error JR0 Platform device creation error caam 2100000.caam: no queues configured, terminating caam: probe of 2100000.caam failed with error -12 The reason is that platform devices are created for each job ring: for_each_available_child_of_node(nprop, np) if (of_device_is_compatible(np, "fsl,sec-v4.0-job-ring") || of_device_is_compatible(np, "fsl,sec4.0-job-ring")) { ctrlpriv->jrpdev[ring] = of_platform_device_create(np, NULL, dev); which sets OF_POPULATED on the device node, but then it cleans these up: /* Remove platform devices for JobRs */ for (ring = 0; ring < ctrlpriv->total_jobrs; ring++) { if (ctrlpriv->jrpdev[ring]) of_device_unregister(ctrlpriv->jrpdev[ring]); } which leaves OF_POPULATED set. Use of_platform_populate / of_platform_depopulate instead. This allows for a bit of driver clean-up, jrpdev is no longer needed. Logic changes a bit too: -exit in case of_platform_populate fails, since currently even QI backend depends on JR; true, we no longer support the case when "some" of the JR DT nodes are incorrect -when cleaning up, caam_remove() would also depopulate RTIC in case it would have been populated somewhere else - not the case for now Cc: Fixes: 313ea293e9c4d ("crypto: caam - Add Platform driver for Job Ring") Reported-by: Russell King Suggested-by: Rob Herring Signed-off-by: Horia Geantă Acked-by: Rob Herring Signed-off-by: Herbert Xu

crypto: ccp - Make some CCP DMA channels private

2017-03-24T13:51:34Z

The CCP registers its queues as channels capable of handling general DMA operations. The NTB driver will use DMA if directed, but as public channels can be reserved for use in asynchronous operations some channels should be held back as private. Since the public/private determination is handled at a device level, reserve the "other" (secondary) CCP channels as private. Add a module parameter that allows for override, to be applied to all channels on all devices. CC: # 4.10.x- Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Assign DMA commands to the channel's CCP

2017-03-16T09:43:08Z

The CCP driver generally uses a round-robin approach when assigning operations to available CCPs. For the DMA engine, however, the DMA mappings of the SGs are associated with a specific CCP. When an IOMMU is enabled, the IOMMU is programmed based on this specific device. If the DMA operations are not performed by that specific CCP then addressing errors and I/O page faults will occur. Update the CCP driver to allow a specific CCP device to be requested for an operation and use this in the DMA engine support. Cc: # 4.9.x- Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

scripts/spelling.txt: add "disble(d)" pattern and fix typo instances

2017-03-10T01:01:09Z

Fix typos and add the following to the scripts/spelling.txt: disble||disable disbled||disabled I kept the TSL2563_INT_DISBLED in /drivers/iio/light/tsl2563.c untouched. The macro is not referenced at all, but this commit is touching only comment blocks just in case.
