Now that the IOMMU driver has been introduced, it prevents any access from a DMA master going through it that hasn't properly mapped the pages, and that link is set up through the iommus property. Unfortunately we forgot to add that property to the video engine node when adding the IOMMU node, so now any DMA access is broken.

No callers of imx_add_imx_dma() need an error IRQ, so they supply 0 as "irq_err", which means we register a resource of IRQ 0, which is invalid and causes a warning if used. Remove the "irq_err" argument altogether so there's no chance of trying to use the invalid IRQ 0.

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build (see our Travis link below). Clang 8 was chosen as a minimum version for this check because there were some improvements around __builtin_constant_p in that release. In reality, MIPS was not even buildable until clang 9 so that check was not technically necessary. Just remove all compiler checks and just assume that we have a working compiler.

In case devlink reload failed, it is possible to trigger a use-after-free when querying the kernel for device info via 'devlink dev info' [1]. This happens because as part of the reload error path the PCI command interface is de-initialized and its mailboxes are freed. When the devlink '->info_get()' callback is invoked the device is queried via the command interface and the freed mailboxes are accessed. Fix this by initializing the command interface once during probe and not during every reload. This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c') and also allows user space to query the running firmware version (for example) from the device after a failed reload.

We should not trigger a warning when a memory allocation fails. Remove the WARN_ON().

Nicolas Ferre says: ==================== net: macb: Wake-on-Lan magic packet fixes and GEM handling Here is a split series to fix WoL magic-packet on the current macb driver. Only fixes in this one based on current net/master. Changes in v5: - Addressed the error code returned by phylink_ethtool_set_wol() as suggested by Russell. If PHY handles WoL, MAC doesn't stay in the way. - Removed Florian's tag on 3/5 because of the above changes. - Correct the "Fixes" tag on 1/5. Changes in v4: - Pure bug fix series for 'net'. GEM addition and MACB update removed: will be sent later. Changes in v3: - Revert some of the v2 changes done in macb_resume(). Now the resume function supports in-depth re-configuration of the controller in order to deal with deeper sleep states. Basically as it was before changes introduced by this series - Tested for non-regression with our deeper Power Management mode which cuts power to the controller completely Changes in v2: - Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()") needed for keeping phy state consistent - Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent putting the macb in runtime pm suspend mode when WoL is used - Collect review tags on 3 first patches from Florian: Thanks! - Review of macb_resume() function - Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers ==================== Signed-off-by: David S.

The calls to pm_runtime_force_suspend/resume() functions are only relevant if the device is not configured to act as a WoL wakeup source. Add the device_may_wakeup() test before calling them.

As we now use the phylink call to phylink_stop() in the non-WoL path, there is no need for this call to netif_carrier_off() anymore. It can disturb the underlying phylink FSM.
