net: designware: add DMA offset awareness

2023-11-05T21:11:38Z

Older DesignWare Ethernet MAC versions that this driver supports can only work with 32-bit DMA source/destination addresses. Some platforms have no physical RAM at the lowest 4GB address space. For these platforms the driver must translate DMA addresses to/from physical memory addresses. Call translation routines so that properly configured platforms can use the DesignWare Ethernet MAC. For platforms using device-tree this usually means adding dma-ranges property to the bus the device node is in. Signed-off-by: Baruch Siach

net: e1000: Drop e1000_eth_ids[]

2023-11-05T21:11:38Z

e1000_eth_ids holds compatible strings for e1000 devices, but it is meaningless as e1000 is a PCI device and there is no such compatible string assigned to e1000 by the DT bindings community. Drop it. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

net: phy: TI DP83869 fix invalid clock delay configuration

2023-11-05T21:11:38Z

Setting the clock delay from the device tree settings rx-internal-delay-ps and tx-internal-delay-ps was broken: - The expected value in the device tree is suppose to be a delay in picoseconds, but the driver only allowed an array index. - Driver converted this array index to the actual delay in picoseconds and tried to apply this in the device register. This however is not a valid register value. The actual logic here was reversed, it converted an register representation of the delay to the device tree delay in picoseconds. Only when the internal delays were NOT configured in the device tree and they default value of 7 (=2000ps) was used, a valid value was loaded in the register. Signed-off-by: Frank de Brabander

net: add hifemac_mdio MDIO bus driver for HiSilicon platform

2023-11-05T21:11:38Z

It adds the driver for the internal MDIO bus of HIFEMAC Ethernet controller. It's based on the mainstream linux driver. Signed-off-by: Yang Xiwen

net: add hifemac Ethernet driver for HiSilicon platform

2023-11-05T21:11:38Z

It adds the driver for HIFEMAC Ethernet controller found on HiSilicon SoCs like Hi3798MV200. It's based on the mainstream linux driver, but quite a lot of code gets rewritten and cleaned up to adopt u-boot driver model. Signed-off-by: Yang Xiwen

net: mv88e6xxx: add Clause 45 support

2023-11-05T21:11:37Z

Marvell LinkStreet switches support Clause 45 MDIO on the internal bus. C45 read or writes require the register address to be written first to the SMI PHY Data register, and then a special C45 Write Address Register OP is used on the SMI PHY Register before making a C45 Read Data Register OP and being able to actually read the register.

net: mv88e6xxx: use generic bitfield macros for MDIO

2023-11-05T18:28:40Z

Driver is currently defining the mask and bit shifting itself, there is no need for that as U-Boot has generic bitfield macros that help us achieve the same result but in a cleaner way. Signed-off-by: Robert Marko

net: ftgmac100: Add reset control

2023-11-05T18:28:40Z

Add optional reset control, especially for the Aspeed SOC. For the hardware without a reset line, the reset assertion/deassertion will be skipped. Signed-off-by: Dylan Hung Reviewed-by: Ryan Chen Reviewed-by: Ramon Fried

sunxi: remove CONFIG_MACPWR

2023-10-22T22:40:56Z

The CONFIG_MACPWR Kconfig symbol is used to point to a GPIO that enables the power for the Ethernet "MAC" (mostly PHY, really). In the DT this is described with the phy-supply property in the MAC DT node, pointing to a (GPIO controlled) regulator. Since we need Ethernet only in U-Boot proper, and use a DM driver there, we should use the DT instead of hardcoding this. Add code to the sun8i_emac and sunxi_emac drivers to check the DT for that regulator and enable it, at probe time. Then drop the current code from board.c, which was doing that job before. This allows us to remove the MACPWR Kconfig definition and the respective values from the defconfigs. Signed-off-by: Andre Przywara Reviewed-by: Sam Edwards
