Fix to return the error code from of_get_child_by_name() instaed of 0 in knav_queue_probe().

2020-11-21soc: ti: Fix reference imbalance in knav_dma_probeZhang Qilong1-2/+11
The patch fix two reference leak. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to call put operation will result in reference leak. 2) The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. We fix it by: 1) adding call pm_runtime_put_noidle or pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable in error handling, to keep usage counter and disable depth balanced.

2020-11-21soc: ti: pruss: Remove wrong check against *get_match_data return valueGrzegorz Jaszczyk1-6/+0
Since the of_device_get_match_data() doesn't return error code, remove wrong IS_ERR test. Proper check against NULL pointer is already done later before usage: if (data && data->...). Additionally, proceeding with empty device data is valid (e.g. in case of "ti,am3356-pruss").

With the integration of chip-id detection scheme in kernel[1], there is no specific need to maintain multitudes of SoC specific config options, discussed as per [2], we have deprecated the usage in other places for v5.10-rc1.

2020-11-03soc/fsl/qbman: Add an argument to signal if NAPI processing is required.Sebastian Andrzej Siewior3-10/+14
dpaa_eth_napi_schedule() and caam_qi_napi_schedule() schedule NAPI if invoked from: - Hard interrupt context - Any context which is not serving soft interrupts Any context which is not serving soft interrupts includes hard interrupts so the in_irq() check is redundant. caam_qi_napi_schedule() has a comment about this: /* * In case of threaded ISR, for RT kernels in_irq() does not return * appropriate value, so use in_serving_softirq to distinguish between * softirq and irq contexts. */ if (in_irq() || !in_serving_softirq()) This has nothing to do with RT. Even on a non RT kernel force threaded interrupts run obviously in thread context and therefore in_irq() returns false when invoked from the handler. The extension of the in_irq() check with !in_serving_softirq() was there when the drivers were added, but in the out of tree FSL BSP the original condition was in_irq() which got extended due to failures on RT. The usage of in_xxx() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. Right he is, the above construct is clearly showing why. The following callchains have been analyzed to end up in dpaa_eth_napi_schedule(): qman_p_poll_dqrr() __poll_portal_fast() fq->cb.dqrr() dpaa_eth_napi_schedule() portal_isr() __poll_portal_fast() fq->cb.dqrr() dpaa_eth_napi_schedule() Both need to schedule NAPI. The crypto part has another code path leading up to this: kill_fq() empty_retired_fq() qman_p_poll_dqrr() __poll_portal_fast() fq->cb.dqrr() dpaa_eth_napi_schedule() kill_fq() is called from task context and ends up scheduling NAPI, but that's pointless and an unintended side effect of the !in_serving_softirq() check. The code path: caam_qi_poll() -> qman_p_poll_dqrr() is invoked from NAPI and I *assume* from crypto's NAPI device and not from qbman's NAPI device. I *guess* it is okay to skip scheduling NAPI (because this is what happens now) but could be changed if it is wrong due to `budget' handling. Add an argument to __poll_portal_fast() which is true if NAPI needs to be scheduled. This requires propagating the value to the caller including `qman_cb_dqrr' typedef which is used by the dpaa and the crypto driver.
