crypto: ccree - split overloaded usage of irq field

2020-01-22T08:21:10Z

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: drivers - Remove dev_err() usage after platform_get_irq()

2019-08-09T05:11:38Z

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

crypto: ccree - drop legacy ivgen support

2019-07-26T04:51:55Z

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. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - prevent isr handling in case driver is suspended

ccree irq may be shared with other devices, in order to prevent ccree isr handling while device maybe suspended we added a check to verify that the device is not suspended. Signed-off-by: Ofir Drang Signed-off-by: Herbert Xu

crypto: ccree - check that cryptocell reset completed

2019-06-27T06:28:00Z

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 Signed-off-by: Herbert Xu
