I have encountered the same issue(s) on A6A boards.

I couldn't find a patch,  so I wrote this patch to update the device tree
in the davinci_mdio driver in the 3.15.1 tree, it seems to correct it. I
would welcome any input on a different approach.

v4.1-rcX: added hack around CONFIG_OF_OVERLAY
v4.2-rc3+: added if (of_machine_is_compatible("ti,am335x-bone")) so we do
not break dual ethernet am335x devices

BeagleBone DTS : Enable run-time pinmux for HDMI Add cape-universal-hdmi pin

bone-pinmux-helper: Add support for "mode" device-tree parameter The new mode parameter is used to set the initial pinmux mode to something other than "default" or NULL, which is what happens currently. This allows enabling SoC hardware via device-tree which requires specific pinmux settings to function on boot, but still leaves the pinmux register under control of the bone-pinmux- helper driver meaning the pinmux setting can be changed at run time via user-mode access to sysfs.

This adds gpio and pinmux helpers to the majority of available expansion header pins
based on the cape-universal work from Charles Steinkuehler making them userspace
configurable. This is not a substitute for Capemgr as it doesn't perform the
configuration based on cape detection, nor does it enable dynamic configuration of
all types of peripherals that could be on a cape. It does, however, enable many
developers to rapidly experiment with a lesser degree of complexity.

A gpio OF helper driver that allows configuration to be done via
DT.

devm_kfree warned out... why? no idea.

Pinctrl already supports multiple states. Just make them visible.

This patch was derived from 2 commits, but I removed the non-pinmux-helper portions
and added the helper to the bb.org_defconfig:

capemgr: Capemgr makefiles and Kconfig fragments.

Introduce a cape loader using DT overlays and dynamic
DT objects.

And:

Pinmux helper driver.

    That's just a hack to get a pinmux helper driver working.

    Define in the DT

    	helper {
    		compatible = "bone-pinmux-helper";
    		pinctrl-names = "default";
    		pinctrl-0 = <&helper_pins>;
    		status = "okay";
    	};

Add support for the WL1835MOD cape.
This cape conflicts with the eMMC and HDMI on board the BeagleBone Black.

This change requires that the board be booted from the SD card slot by
holding the user/boot button down at power on and reset.

Added pin mux definitions for collision and carrier sense errors coming
from the ethernet phy. Without these two signals the MAC ends up ignoring
the errors detected by the PHY which end up causing a lower throughput
problem when the phy is in half duplex mode such as connected through a hub.

This probably misplaced (in drivers/misc) patch allows use
of device tree overlays on the two kinds of probeable busses
that count nowadays, PCI & USB.

It does so by dynamically creating device nodes for the busses &
devices that are probed and according to user-configuration applying
an overlay when they appear.

It is still a WIP but it's coming along nicely.

Issues: Only PCI works for now, the generated bindings are not
correct according to the openfirmware spec.

Changesets are very powerful, but the lack of a helper API
makes using them cumbersome. Introduce a simple copy based
API that makes things considerably easier.

To wit, adding a property using the raw API.

	struct property *prop;
	prop = kzalloc(sizeof(*prop)), GFP_KERNEL);
	prop->name = kstrdup("compatible");
	prop->value = kstrdup("foo,bar");
	prop->length = strlen(prop->value) + 1;
	of_changeset_add_property(ocs, np, prop);

while using the helper API

	of_changeset_add_property_string(ocs, np, "compatible",
			"foo,bar");

The target facility of an overlay allows the target to be any point
in the live kernel tree, since it usually that's required when
creating overlays for internal SoC devices. The target ends up
to be a single node in the tree.

However when we're dealing with probeable busses this is a problem
since the target node differs according to the bus the plugged
device lies.

Using an overlay creating method using a target root node allows
us to use a single overlay for those cases.
