    crypto: mxs - Remove the old DCP driver · c493c044
    Marek Vasut authored
    Remove the old DCP driver as it had multiple severe issues. The driver
    will be replaced by a more robust implementation. Here is a short list
    of problems with this driver:
    
    1) It only supports AES_CBC
    2) The driver was apparently never ran behind anyone working with MXS. ie.:
       -> Restarting the DCP block is not done via mxs_reset_block()
       -> The DT name is not "fsl,dcp" or "fsl,mxs-dcp" as other MXS drivers
    3) Introduces new ad-hoc IOCTLs
    4) The IRQ handler can't use usual completion() in the driver because that'd
       trigger "scheduling while atomic" oops, yes?
