* fsl/fman: remove unnecessary set_dma_ops() call and HAS_DMA dependencyMadalin Bucur2018-03-26
| | | | | | | | | | The platform device is no longer used for DMA mapping so the (questionable) setting of the DMA ops done here is no longer needed. Removing it together with the HAS_DMA dependency that it required. Signed-off-by: Madalin Bucur <madalin.bucur@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* fsl/fman: Remove some useless codeChristophe JAILLET2017-11-07
| | | | | | | | | | | | | | There is no need to release explicitly some devm_ allocated resources. If the 'mac_probe()' probe function fails, they will be released automatically, as already done in the other error handling paths of this function. Also goto '_return_of_get_parent' as in the other error handling paths. This is useless (priv->fixed_link is NULL at this point), but at least it is consistent.

* dpaa_eth: change device usedMadalin Bucur2017-10-18
| | | | | | | | | | Change device used for DMA mapping to the MAC device that is an of_device, with proper DMA ops. Using this device for the netdevice should also address the issue with DSA scenarios that need the netdevice to be backed by an of_device.

* fsl/fman: remove of_nodeMadalin Bucur2017-10-18
| | | | | | | | | | | | | | | | | The FMan MAC driver allocates a platform device for the Ethernet driver to probe on. Setting pdev->dev.of_node with the MAC node triggers the MAC driver probing of the new platform device. While this fails quickly and does not affect the functionality of the drivers, it is incorrect and must be removed. This was added to address a report that DSA code using of_find_net_device_by_node() is unable to use the DPAA interfaces. Error message seen before this fix: fsl_mac dpaa-ethernet.0: __devm_request_mem_region(mac) failed fsl_mac: probe of dpaa-ethernet.0 failed with error -16 Signed-off-by: Madalin Bucur <madalin.bucur@nxp.com> Signed-off-by: David S.

| * fsl/man: Inherit parent device and of_nodeFlorian Fainelli2017-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Junote Cai reported that he was not able to get a DSA setup involving the Freescale DPAA/FMAN driver to work and narrowed it down to of_find_net_device_by_node(). This function requires the network device's device reference to be correctly set which is the case here, though we have lost any device_node association there. The problem is that dpaa_eth_add_device() allocates a "dpaa-ethernet" platform device, and later on dpaa_eth_probe() is called but SET_NETDEV_DEV() won't be propagating &pdev->dev.of_node properly. Fix this by inherenting both the parent device and the of_node when dpaa_eth_add_device() creates the platform device.

It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
