* net: phy: micrel: Add workaround for bad autonegPhilipp Zabel2016-02-041-1/+22
| | | | | | | | | | | | | Based on kernel commit d2fd719bcb0e ("net/phy: micrel: Add workaround for bad autoneg") by Nathan Sullivan <nathan.sullivan@ni.com>: Very rarely, the KSZ9031 will appear to complete autonegotiation, but will drop all traffic afterwards. When this happens, the idle error count will read 0xFF after autonegotiation completes. Reset the PHY when in that state.

| | | | | | | | | | | | | This commit changes the behaviour of the 'miitool'.

| | | | | | | | | | | | | Change the way PHY devices are named upon creation. This commit replaces sequentialy numbered "/dev/phy%d" with "/dev/mdio%d-phy%02x". This way it is significanlty easier to identify which PHY in real-life (e.g. on a schematic) corresponds to which device in /dev. Also, replace asprintf with xasprintf to provide some form of memory allocation failure checking.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ax_skb receive buffer unalignment leads to consequent unalignment data access in network stack routines, especially in net_checksum(). By-turn unalignment data accesses lead to performance penalty. Moreover on classic MIPS CPUs without hardware unalignment access support this leads to undesirable exceptions. At the moment barebox on MIPS can't parry these unalignment access exceptions, so the Asix USB Ethernet chips, that need receive fixup workaround, are completely unusable on MIPS without this patch.

| * net: designware: Don't hang in reset with powered down phyTrent Piepho2015-11-131-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dw MAC requires that all clock domains to be running for it to finish a MAC reset. This include the clock provided by the PHY. If the PHY is powered down, bit BMCR_PDOWN set, then it won't be generating a clock. And so the MAC never comes out of reset. On shutdown, Linux will put the PHY in powerdown mode, so it can easily be the case that the PHY is powered down on boot. See Linux kernel commit 2d871aa07136fe6e576bde63072cf33e2c664e95. Currently the MAC reset is done before the phy is probed. We can't power up the phy until it's probed, so the resets must be in the opposite order. The MAC reset is in device init but the PHY probe is in device open. Device init is done first, always, while open is done later, and only if the device is used. Rather than move the phy probe to init, this moves the MAC reset to open. It seems better to speed up boots that doesn't use ethernet by skipping MAC reset than to slow them down by adding PHY probe.

Without this reset some devices fail to initialise correctly on system startup. N.B. DM9000B on MIPS Creator CI20 board needs additional workaround (see the 'Make all GPIO pins outputs' and 'Power internal PHY' lines). This workaround was taken from this U-boot's commit: commit fbcb7ece0ea1e364180f1cf963e0fa0ce7f6560d Author: Remy Bohmer <linux@bohmer.net> Date: Tue Jun 3 15:26:24 2008 +0200 DM9000: Improve eth_reset() routine According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the reset procedure must be done twice to properly reset the DM9000 by means of software.
