While it is not yet understood why a TX underflow can easily occur
for SGMII interfaces resulting in a TX wedge. It has been found that
disabling/re-enabling the LMAC resolves the issue.

The configuration of the OCTEONTX XCV_DLL_CTL register via
xcv_init_hw() is such that the RGMII RX delay is bypassed
leaving the RGMII TX delay enabled in the MAC:
/* Configure DLL - enable or bypass
* TX no bypass, RX bypass
*/
cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
cfg &= ~0xFF03;
cfg |= CLKRX_BYP;
writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);
This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
and not PHY_INTERFACE_MODE_RGMII.
Fixing this allows RGMII PHY drivers to do the right thing (enable
RX delay in the PHY) instead of erroneously enabling both delays in the
PHY.

set_edid never wrote the new EDID to state->edid.edid, it was only
written to the hardware. Since get_edid returned state->edid.edid,
it was never returning the right EDID.

Remove the sky2 ethernet device node from the pcie controller which was
invalid to begin with.
The original intent was to allow the bootloader to populate the MAC via
dt but this requires the PCI bus topology to be complete in dt as well
and as these boards have an expansion connector that topology is dynamic
and can't be represented here.

All of the Gateworks Ventana boards based on the IMX6 SoC except for the
GW54xx use the LTC3676 PMIC. Add a device-tree node with interrupt support
for this PMIC. Additionally remove the simple-bus notation in the regulator

bc677ff42e adds a device-tree property
to specify that an external watchdog reset is used to reset other
portions of the board and not just the IMX6 SoC.
This adds the property to the proper watchdog as well as the pinmux for
the Gateworks Ventana boards that use this external watchdog reset to
reset the PMIC which will reset all the PMIC power rails and not just
a chip-level IMX6 reset. This helps to work around various system issues
that can cause a hang when coming out of reset.
