* crypto: ccree - split overloaded usage of irq fieldGilad Ben-Yossef2020-01-221-3/+1
| | | | | | | | | | | | | | We were using the irq field of the drvdata struct in an overloaded fahsion - saving the IRQ number during init and then storing the pending itnerrupt sources during interrupt in the same field. This worked because these usage are mutually exclusive but are confusing. So simplify the code and change the init use case to use a simple local variable.

* crypto: ccree - fix PM race conditionGilad Ben-Yossef2020-01-221-0/+1
| | | | | | | | | | | The PM code was racy, possibly causing the driver to submit requests to a powered down device. Fix the race and while at it simplify the PM code.

| | | | | | | | The define of CC_DEV_SHA_MAX is not needed since we moved to runtime detection of capabilities. Remove it. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ccree - drop legacy ivgen supportGilad Ben-Yossef2019-07-261-10/+0
| | | | | | | | | ccree had a mechanism for IV generation which was not compatible with the Linux seqiv or echainiv iv generator and was never used in any of the upstream versions so drop all the code implementing it.

* crypto: ccree - check that cryptocell reset completedOfir Drang2019-06-271-0/+3
| | | | | | | | | | | In case of driver probe and pm resume we need to check that the cryptocell hardware reset cycle is completed. during the reset cycle that Cryptocell provide read only access to the APB interface which allows to verify through the CC registers that the reset is completed. Until reset completion we assume that any write/crypto operation is blocked. Signed-off-by: Ofir Drang <ofir.drang@arm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ccree - don't map AEAD key and IV on stackGilad Ben-Yossef2019-04-251-0/+1

* crypto: ccree - simplify fragment ICV detectionGilad Ben-Yossef2019-04-251-1/+0
| | | | | | | | | | | | | The code detecting whether the ICV is fragmented was overly complex and limited the number of fragments an ICV may be comprised of with no reason in the current code, casuing the new testmgr tests to fail. This patch removes this legacy limitation and greatly simplifies the code. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | The product signature and HW revision register have different offset on the older HW revisions. This fixes the problem of the driver failing sanity check on silicon despite working on the FPGA emulation systems.
