Do not lock driver mutex in the global LED panel brightness sysfs accessors brightness_show() and brightness_store(). The mutex locking is unnecessary here. The I2C transfers are guarded by I2C core locking mechanism, and the LED commands itself do not interfere with other commands.

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.

2023-08-18drm: bridge: samsung-dsim: Fix init during host transferFrieder Schrempf
In case the downstream bridge or panel uses DSI transfers before the DSI host was actually initialized through samsung_dsim_atomic_enable() which clears the stop state (LP11) mode, all transfers will fail. This happens with downstream bridges that are controlled by DSI commands such as the tc358762. As documented in [1] DSI hosts are expected to allow transfers outside the normal bridge enable/disable flow. To fix this make sure that stop state is cleared in samsung_dsim_host_transfer() which restores the previous behavior. We also factor out the common code to enable/disable stop state to samsung_dsim_set_stop_state().
