2014-11-06crypto: caam - fix missing dma unmap on error pathCristian Stoica1-15/+14
If dma mapping for dma_addr_out fails, the descriptor memory is freed but the previous dma mapping for dma_addr_in remains. This patch resolves the missing dma unmap and groups resource allocations at function start.

2014-09-24crypto: ccp - Check for CCP before registering crypto algsTom Lendacky2-0/+18
If the ccp is built as a built-in module, then ccp-crypto (whether built as a module or a built-in module) will be able to load and it will register its crypto algorithms. If the system does not have a CCP this will result in -ENODEV being returned whenever a command is attempted to be queued by the registered crypto algorithms. Add an API, ccp_present(), that checks for the presence of a CCP on the system. The ccp-crypto module can use this to determine if it should register it's crypto alogorithms.

2014-08-25crypto: caam - change starting entropy delay valueAlex Porosanu2-1/+10
The entropy delay (the length in system clocks of each entropy sample) for the RNG4 block of CAAM is dependent on the frequency of the SoC. By elaborate methods, it has been determined that a good starting value for all platforms integrating the CAAM IP is 3200. Using a higher value has additional benefit of speeding up the process of instantiating the RNG, since the entropy delay will be increased and instantiation of the RNG state handles will be reattempted by the driver. If the starting value is low, for certain platforms, this can lead to a quite lengthy process. This patch changes the starting value of the length of the entropy sample to 3200 system clocks. In addition to this change, the attempted entropy delay values are now printed on the console upon initialization of the RNG block. While here, a safeguard for yielding the processor was added for ensuring that in very adverse cases, the CPU isn't hogged by the instantiation loop.

2014-08-25crypto: caam - disable RNG oscillator maximum frequency checkAlex Porosanu2-2/+3
The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

2014-07-24crypto: ccp - Remove "select OF" from KconfigTom Lendacky1-1/+0
The addition of the "select OF if ARM64" has led to a Kconfig recursive dependency error when "make ARCH=sh rsk7269_defconfig" was run. Since OF is selected by ARM64 and the of_property_read_bool is defined no matter what, delete the Kconfig line that selects OF.

2014-07-24of: Reorder device tree changes and notifiersGrant Likely1-22/+8
Currently, devicetree reconfig notifiers get emitted before the change is applied to the tree, but that behaviour is problematic if the receiver wants the determine the new state of the tree. The current users don't care, but the changeset code to follow will be making multiple changes at once. Reorder notifiers to get emitted after the change has been applied to the tree so that callbacks see the new tree state. At the same time, fixup the existing callbacks to expect the new order. There are a few callbacks that compare the old and new values of a changed property. Put both property pointers into the of_prop_reconfig structure. The current notifiers also allow the notifier callback to fail and cancel the change to the tree, but that feature isn't actually used. It really isn't valid to ignore a tree modification provided by firmware anyway, so remove the ability to cancel a change to the tree.
