bcmgenet: Add support for rgmii-rxid

2020-09-08T14:43:48Z

The commit 57805f2270c4 ("net: bcmgenet: Don't set ID_MODE_DIS when not using RGMII") needed to be extended for the case of using the rgmii-rxid. The latest version of the Rasbperry Pi4 dtb files for the 5.4 now specify the rgmii-rxid. Signed-off-by: Jason Wessel Tested-by: Petr Tesarik Signed-off-by: Matthias Brugger

bcmgenet: fix DMA buffer management

2020-09-08T14:43:02Z

This commit fixes a serious issue occurring when several network commands are run on a raspberry pi 4 board: for instance a "dhcp" command and then one or several "tftp" commands. In this case, packet recv callbacks were called several times on the same packets, and send function was failing most of the time. note: if the boot procedure is made of a single network command, the issue is not visible. The issue is related to management of the packet ring buffers (producer / consumer) and DMA. Each time a packet is received, the ethernet device stores it in the buffer and increments an index called RDMA_PROD_INDEX. Each time the driver outputs a received packet, it increments another index called RDMA_CONS_INDEX. Between each pair of network commands, as part of the driver 'start' function, previous code tried to reset both RDMA_CONS_INDEX and RDMA_PROD_INDEX to 0. But RDMA_PROD_INDEX cannot be written from driver side, thus its value was actually not updated, and only RDMA_CONS_INDEX was reset to 0. This was resulting in a major synchronization issue between the driver and the device. Most visible behavior was that the driver seemed to receive again the packets from the previous commands (e.g. DHCP response packets "received" again when performing the first TFTP command). This fix consists in setting RDMA_CONS_INDEX to the same value as RDMA_PROD_INDEX, when resetting the driver. The same kind of fix was needed on the TX side, and a few variables had to be reset accordingly (c_index, tx_index, rx_index). The rx_index and tx_index have only 256 entries so the bottom 8 bits must be masked off.

net: dwc_eth_qos: add Kconfig option to select supported configuration

2020-08-05T03:30:02Z

Add configuration flag to select the supported dwc driver configuration: - CONFIG_DWC_ETH_QOS_TEGRA186 - CONFIG_DWC_ETH_QOS_IMX - CONFIG_DWC_ETH_QOS_STM32 See Linux driver ethernet/stmicro/stmmac and associated glue layers for other configuration examples. This patch removes the not-selected compatibles and lets the linker remove the unused functions to reduce the size of the driver. Signed-off-by: Patrick Delaunay

eth: mtk-eth: enable mt7629 sgmii mode support in mediatek eth driver

2020-07-29T02:44:00Z

The sgmii mode init flow is almost the same for all mediatek SoC, the only difference is the register offset(SGMSYS_GEN2_SPEED) is 0x2028 in the old chip(mt7622) but changed to 0x128 for the newer chip(mt7629 and the following chips). Signed-off-by: MarkLee
