* net: designware: eqos: stm32: drop no longer needed syscfg-clkAhmad Fatoum2020-02-191-2/+1
| | | | | | | | | | | | The upstream device tree no longer lists "syscfg-clk" and the syscon node contains a clocks property that the barebox syscon driver now automatically clocks before access. Thus drop the requirement that "syscfg-clk" is specified.

* net: designware: socfpga: fix possible invalid pointer derefAhmad Fatoum2020-02-121-10/+8
| | | | | | | | | | | | | | In cases where the reset controller specification in the device tree is malformed, we get an error pointer back from reset_control_get. This compares unequal to NULL and would cause an access violation when passed to reset_control_(de)?assert. Fix this by propagating the error. When the reset controller is missing, reset_control_(de)?assert will be passed NULL pointers, rendering them no-ops.

* net: designware: eqos: don't funnel all MDIO writes to register 0Ahmad Fatoum2020-01-201-3/+3
| | | | | | | | | | | | | | | | eqos_mdio_write ended up using the addr parameter instead of the computed miiaddr variable, which would've factored in the reg parameter. This had the effect that all writes went to PHY register 0, which was fine as long as there were only register 0 writes. As soon there are more writes, e.g. because a PHY driver was enabled, register 0 became clobbered and erratic behavior ensued. Fix the typo and while at it rename the val parameter to a more descriptive name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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".

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>

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.
