net: sun8i_emac: Retrieve GMAC clock via 'syscon' phandle

2019-04-16T10:59:01Z

Unlike other Allwinner SoC's R40 GMAC clock control register is locate in CCU, but rest located via syscon itself. Since the phandle property for current code look for 'syscon' and it will grab the respective ccu or syscon base address based on DT property defined in respective SoC dtsi. So, use the existing 'syscon' code even for R40 for retrieving GMAC clock via CCU and update the register directly in sun8i_emac_set_syscon instead of writing it separately using ccm base.

sun8i_emac: add support for setting EMAC TX/RX delay

2018-11-23T05:31:09Z

Some boards have the EMAC TX/RX lanes wired with a different length with the clock lane, which can be workarounded by setting a TX/RX delay in the EMAC. This kind of delays are already defined in the newest device tree binding of dwmac-sun8i, which has already entered linux-next. Add support for setting these delays.

net: sun8i-emac: support R40 GMAC

2018-07-16T06:57:27Z

Add support for the GMAC found in the Allwinner R40/V40 SoC. The R40 GMAC interface is not controlled by the syscon register but has a separate configuration register in the CCU. The clock gate and reset bits are in a different register compared to the other SoCs supported by this driver. The driver uses the -gmac suffix for the R40 because the R40 also has a different 100 MBit MAC (EMAC). Signed-off-by: Lothar Felten Reviewed-by: Jagan Teki Tested-by: Jagan Teki

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

net: sun8i-emac: remove support for old binding

2018-04-04T06:01:35Z

The original DT binding used by U-Boot's sun8i-emac driver was not really agreed upon, and deviated from the "official" binding now used by the kernel. Since now all U-Boot users have been converted to the new binding, we can remove support for the old DT nodes from the driver.

net: sun8i-emac: add support for new EMAC DT binding

2018-04-04T06:01:35Z

The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an upstream Linux driver in v4.15. This one uses a slightly different binding from the original one used by the U-Boot driver. The differences to the old binding are: - The "syscon" address is held in a separate node, referenced via a phandle in the "syscon" property. - The reference to the PHY is held in a property called "phy-handle", not "phy". - The PHY register is at offset 0x30 in the syscon device, not at 0. - The internal PHY is activated when the node, which phy-handle points to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node. Teach the U-Boot driver how to find its resources in a "new-style" DT, so that we can use a Linux kernel compatible DT for U-Boot as well. This keeps support for the old binding for now, to allow a smooth transition. Signed-off-by: Andre Przywara Acked-by: Maxime Ripard Reviewed-by: Jagan Teki
