crypto: ccree - fix resume race condition on init

2019-02-08T07:28:02Z

We were enabling autosuspend, which is using data set by the hash module, prior to the hash module being inited, casuing a crash on resume as part of the startup sequence if the race was lost. This was never a real problem because the PM infra was using low res timers so we were always winning the race, until commit 8234f6734c5d ("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-) Fix this by seperating the PM setup and enablement and doing the latter only at the end of the init sequence.

crypto: ccree - no need to check return value of debugfs_create functions

2019-02-01T06:42:03Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

crypto: ccree - shared irq lines are not a bug

2019-01-25T10:41:51Z

The ccree driver was logging an error if it got an interrupt but HW indicated nothing to do as might happen if sharing an irq line. Remove the error as this is normal and we already have a debug print for the IRR register value. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add support for CryptoCell 703

2018-12-07T06:14:59Z

Add support for Arm TrustZone CryptoCell 703. The 703 is a variant of the CryptoCell 713 that supports only algorithms certified by the Chinesse Office of the State Commercial Cryptography Administration (OSCCA). Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - adjust hash length to suit certain context specifics

2018-11-09T09:36:49Z

Adjust hash length such that it will not be fixed and general for all algs. Instead make it suitable for certain context information. This is preparation for SM3 support. Signed-off-by: Yael Chemla Signed-off-by: Herbert Xu

crypto: ccree - add support for CryptoCell 713

2018-11-09T09:36:49Z

Add support for Arm TrustZone CryptoCell 713. Note that this patch just enables using a 713 in backwards compatible mode to 712. Newer 713 specific features will follow. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - rate limit debug print

2018-07-08T16:33:36Z

A debug print about register status post interrupt can happen quite often. Rate limit it to avoid cluttering the log. Signed-off-by: Gilad Ben-Yossef Reported-by: Geert Uytterhoeven Tested-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - silence debug prints

2018-05-30T16:13:50Z

The cache parameter register configuration was being too verbose. Use dev_dbg() to only provide the information if needed. Signed-off-by: Gilad Ben-Yossef Reviewed-by: Simon Horman Signed-off-by: Herbert Xu

crypto: ccree - better clock handling

2018-05-30T16:13:49Z

Use managed clock handling, differentiate between no clock (possibly OK) and clock init failure (never OK) and correctly handle clock detection being deferred. Suggested-by: Geert Uytterhoeven Signed-off-by: Gilad Ben-Yossef Reviewed-by: Simon Horman Signed-off-by: Herbert Xu
