| * net: eqos: extend Designware Ethernet QoS for Tegra 186 supportAhmad Fatoum2019-11-063-0/+354
| | | | | | | | | | | | | | | | | | | | | | | | The U-Boot dwc_eth_qos driver ported in the previous commit had support for both the Tegra 186/194 and STM32MP variants of the EQOS IP. The barebox Tegra supported doesn't include the 186, but as the driver was nevertheless ported along with the rest, lets include it in the source tree.

| * net: add Designware Ethernet QoS for STM32MPAhmad Fatoum2019-11-065-1/+1227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have Designware NIC support in barebox, but for the DWMAC1000, the DWMAC4 (also called GMAC4), no support was mainline so far. The DWMAC4 is different enough that sharing code with the DWMAC1000 is not really that helpful, because even basics like MDIO registers have different layout. Instead of coding bit masks and shifts into the driver data, like Linux does, we'll keep both driver kinds separate. Nevertheless, we collect functions that are not SoC-specific into a separate 'library' file. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | net: designware: socfpga: fix phy setup for Arria10Steffen Trumtrar2019-10-182-16/+118
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Barebox-version of the Linux v5.2 patch: 40ae25505fe834648ce4aa70b073ee934942bfdb net: stmmac: socfpga: fix phy and ptp_ref setup for Arria10/Stratix10 On the Arria10, Agilex, and Stratix10 SoC, there are a few differences from the Cyclone5 and Arria5: - The emac PHY setup bits are in separate registers. - The PTP reference clock select mask is different. - The register to enable the emac signal from FPGA is different. Thus, this patch creates a separate function for setting the phy modes on Arria10/Agilex/Stratix10. The separation is based a new DTS binding: "altr,socfpga-stmmac-a10-s10".

| | | | | | | | | | | | | | | | | | | | | | | | | | Ethernet support for ar9331 is upstream now. So, drop every thing what is provided by upstream devicetree and rename compatible in the driver. barebox network driver will need more work to be upstream compliant. For example we should not request or touch the gmac register directly. Since currently it is not clear how this should be implemented, patch the upstream dts with reg-names = "ge0", "gmac".

| * net: dsa: mv88e6xxx: Wait for EEPROM done after HW resetAndrey Smirnov2019-10-145-0/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a unpublished patch from Andrew Lunn: When the switch is hardware reset, it reads the contents of the EEPROM. This can contain instructions for programming values into registers and to perform waits between such programming. Reading the EEPROM can take longer than the 100ms mv88e6xxx_hardware_reset() waits after deasserting the reset GPIO. So poll the EEPROM done bit to ensure it is complete.

* net: cpsw: adopt to upstream device tree changesSascha Hauer2019-07-101-6/+10
| | | | | | | | | | | | | | | | | Upstream device trees no longer have a "cpsw-phy-sel" property to find the phy_sel register, instead they have a child device of the pinctrl node compatible to "ti,am3352-phy-gmii-sel". Also the "rmii-clock-ext" property is no longer global to the cpsw but instead can be selected per slave. To adopt to these changes take the short way out for now and find the new node by its compatible and hardcode the "rmii-clock-ext" setting (which is set to true in am33xx-l4.dtsi and not overwritten by any board). This makes the cpsw driver work again. Tested on Beaglebone black board. Fixes: 1dc748b3b2 ("dts: update to v5.1-rc1") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* / ARM: at91: replace __raw_{readl, writel} of peripherals with readl, writelAhmad Fatoum2019-05-242-6/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Use the potentially endianness-changing readl, writel and siblings directly. They looks prettier and are the correct thing to do, as even if the CPU is in big-endian mode, the peripherals are little-endian. Unlike Linux, barebox readl,writel are the same Linux' {readl,writel}_relaxed (they don't imply memory barriers) and thus there shouldn't be any functional change. Patch was generated by a mass search and replace. I looked it over, adjust some whitespace and further verified by reviewing the output of git diff HEAD~1 --word-diff | \ perl -pe 's/\[-(.*?)__raw_/{+$1/; s/-\]\{\+/+}{+/;' \ -e 's/(\{\+.*?\+\})\1/__ALL_IS_WELL__/' | grep '+}{+' which filters out the common case of lines where a single __raw_{readT,writeT} had its __raw_ prefix stripped without any further changes.

The clock signal must meet the RGMII requirements to ensure the correct data transmission between the MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle requirement if the phy is configured as slave. For a complete describtion look at the errata sheets: DS80000691D or DS80000692D. The errata sheet recommends to force the phy into master mode whenever there is a 1000Base-T link-up as work around. Only set the "micrel,force-master" property if you use the phy reference clock provided by CLK125_NDO pin as MAC reference clock in your application. Attenation, this workaround is only usable if the link partner can be configured to slave mode for 1000Base-T.
