Also when warm reboot, uboot can not access the sd slot Cause: Identified by Robin Murphy @ ARM. The Card Detect on rk3288 devices is pulled up by vccio-sd; so when the regulator powers this off, card detect gives spurious errors. A second problem, is during power down, vccio-sd apprears to be powered down. This causes a problem when warm rebooting from the sd card. This was identified by Jonas Karlman. History: A common fault on these rk3288 board, which impliment the reference design. When this arose before: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/281153.html And Ulf and Jaehoon clearly said this was a broken card detect design, which should be solved via polling Solution: Hence broken-cd is set as a property. This cures the errors. The powering down of vccio-sd during reboot is cured by adding regulator-boot-on. This solutions has been fairly widely reviewed and tested.

When looking at all the users of this function, I discovered that all instances pass in only 0 and 6 for these arguments. Instead of having this function handle different cases that are never used, simply rewrite it to return the first 6 arguments of a system call. This should help out the performance of tracing system calls by ptrace, ftrace and perf.

The end result is that the boards can no longer obtain an IP address via UDHCP, for example. Quoting Andrew Lunn: "The problem here is, all the DTs were broken since day 0. However, because the PHY driver was also broken, nobody noticed and it worked. Now that the PHY driver has been fixed, all the bugs in the DTs now become an issue" To fix this problem, the phy-mode property needs to be "rgmii-id", which has the following meaning as per Documentation/devicetree/bindings/net/ethernet.txt: "RGMII with internal RX and TX delays provided by the PHY, the MAC should not add the RX or TX delays in this case)" Tested on imx6-sabresd, imx6sx-sdb and imx7d-pico boards with successfully restored networking. Based on the initial submission from Steve Twiss for the imx6qdl-sabresd.

This patch adds a small delay, so when the 3.3V regulator comes on it delays a bit before the subsequent regulators can come on. This reduces the inrush current a bit on the external DC power supply to help prevent a situation where the sourcing power supply cannot source enough current and overloads and the kit fails to start.

But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC are pointing towards the same internal PCS. Therefore nobody is controlling the internal PCS of eTSEC0. Upon initial ndo_open, the SGMII link is ok by virtue of U-boot initialization. But upon an ifdown/ifup sequence, the code path from ndo_open -> init_phy -> gfar_configure_serdes does not get executed for the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII link remains down for eTSEC0. On the LS1021A-TWR board, to signal this failure condition, the PHY driver keeps printing '803x_aneg_done: SGMII link is not ok'. Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match mdio1 device.
