2023-08-18crypto: caam/jr - fix shared IRQ line handlingHoria Geantă
There are cases when the interrupt status register (JRINTR) is non-zero, even though: 1. An interrupt was generated, but it was masked OR 2. There was no interrupt generated at all for the corresponding job ring. 1. The case when interrupt is masked (JRCFGR_LS[IMSK]=1b'1) while other events have happened and are being accounted for, e.g. -JRINTR[HALT]=2b'10 - input job ring underwent a flush of all on-going jobs and processing of still-existing jobs (sitting in the ring) has been halted -JRINTR[HALT]=2b'01 - input job ring is currently undergoing a flush -JRINTR[ENTER_FAIL]=1b'1 - SecMon / SNVS transitioned to FAIL MODE It doesn't matter whether these events would assert the interrupt signal or not, interrupt is anyhow masked. 2. The case when interrupt is not masked (JRCFGR_LS[IMSK]=1b'0), however the events accounted for in JRINTR do not generate interrupts, e.g.: -JRINTR[HALT]=2b'01 -JRINTR[ENTER_FAIL]=1b'1 and JRCFGR_MS[FAIL_MODE]=1b'0 Currently in these cases, when the JR interrupt handler is invoked (as a consequence of JR sharing the interrupt line with other devices - e.g. the two JRs on i.MX7ULP) it continues execution instead of returning IRQ_NONE. This could lead to situations like interrupt handler clearing JRINTR (and thus also the JRINTR[HALT] field) while corresponding job ring is suspended and then that job ring failing on resume path, due to expecting JRINTR[HALT]=b'10 and reading instead JRINTR[HALT]=b'00. Fix this by checking status of JRINTR[JRI] in the JR interrupt handler. If JRINTR[JRI]=1b'0, there was no interrupt generated for this JR and handler must return IRQ_NONE.

2023-08-18crypto: caam - increase the domain of write memory barrier to full systemIuliana Prodan
In caam_jr_enqueue, under heavy DDR load, smp_wmb() or dma_wmb() fail to make the input ring be updated before the CAAM starts reading it. So, CAAM will process, again, an old descriptor address and will put it in the output ring. This will make caam_jr_dequeue() to fail, since this old descriptor is not in the software ring. To fix this, use wmb() which works on the full system instead of inner/outer shareable domains.

2023-08-11crypto: stm32 - Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

The check for hdev being non-NULL can be dropped because hdev is never NULL (or something bad like memory corruption happened and then the check doesn't help any more either).

2023-08-11crypto: stm32 - Properly handle pm_runtime_get failingUwe Kleine-König
If pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, this means the clk wasn't prepared and enabled. Returning early in this case however is wrong as then the following resource frees are skipped and this is never catched up. So do all the cleanups but clk_disable_unprepare(). Also don't emit a warning, as stm32_hash_runtime_resume() already emitted one. Note that the return value of stm32_hash_remove() is mostly ignored by the device core. The only effect of returning zero instead of an error value is to suppress another warning in platform_remove(). So return 0 even if pm_runtime_resume_and_get() failed.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
