* ramips: improve ethernet driver performance with GRO/TSOFelix Fietkau2018-06-193-76/+105
| | | | | | | | | | | GRO stores packets as fraglist. If they are routed back to the ethernet device, they need to be re-segmented if the driver does not support sending fraglists. Add the missing support for that, along with a missing feature flag that allows full routed GRO->TSO offload. Considerably reduces CPU utilization for routing Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ramips: mt7621: fix mtu setting with kernel 4.14Mathias Kresin2018-06-161-11/+7
| | | | | | | | | | Since kernel 4.10 commit 61e84623ace3 ("net: centralize net_device min/max MTU checking"), the range of mtu is [min_mtu, max_mtu], which is [68, 1500] by default. It's necessary to set a max_mtu if a mtu > 1500 is supported. Signed-off-by: Mathias Kresin <dev@kresin.me>

* ramips: mmc: Sync with staging driverRosen Penev2018-05-185-3417/+2693
| | | | | | | | | | | | | | Mostly whitespace cleanups. Some unneeded code was removed. MMC init was also moved to the probe function as in 6069bdd The cleanup commits are over 100, making it hard to do them individually. Tested on GnuBee PC1 with an SD card being used as swap.

* ramips: remove unnecessary resource details.NeilBrown2018-05-141-15/+2
| | | | | | | | These resources are extracted from devicetree, so they aren't needed here. Signed-off-by: NeilBrown <neil@brown.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* ramips: remove conditional compilation.NeilBrown2018-05-141-58/+8
| | | | | | | | | | | | | Code currently defines: and then compiles code only if they are defined. We might want to disable some of these via devicetree one day, but for now just remove the #defines and the conditions - all the code for different ports is easy to identify.

* ramips: improve interrupt mappingNeilBrown2018-05-141-65/+9
| | | | | | | | | | | | | | As the Interrupts for the PCI adapters are listed in devicetree we shouldn't need to have them explicit in the code. The simplest way to do this is to use of_irq_parse_and_map_pci() and specify an interrupt-map which identifies the different PCI hosts by bus/slot numbers. This has the advantage that the hwirq number are mapped to virq numbers for us, so the ugly hack can go.

* ramips: mtk-mmc: don't advertise highmem support.NeilBrown2018-04-051-0/+1
| | | | | | | | | | | | | | | | of_dma_configure() sets a default ->dma_mask of DMA_BIT_MASK(32), claiming devices can DMA from the full 32bit address space. The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space). Setting ->dma_mask to NULL causes mmc_setup_queue() to fall-back to using BLK_BOUNCE_HIGH to tell the block layer to use a bounce-buffer for any highmem pages requiring IO.
