net: phy: add ofnode node to struct phy_device

2018-07-26T19:08:22+00:00

Now the UCLASS_ETH device "node" field is owerwritten by some network drivers in
case of Ethernet PHYs which are linked to UCLASS_ETH device using
"phy-handle" DT property and when Ethernet PHY driver needs to read some
additional information from DT. In such cases following happens (in
general):

- network drivers
	priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev,
				   priv->interface);
	<-- phydev is connected to dev which is UCLASS_ETH device

	if (priv->phy_of_handle > 0)
		dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle);
	<-- phydev->dev->node is overwritten by phy-handle DT node

- PHY driver in .config() callback
	int node = dev_of_offset(dev);
	<-- PHY driver uses overwritten dev->node
        const void *fdt = gd->fdt_blob;

	 if (fdtdec_get_bool(fdt, node, "property"))
		...

As result, UCLASS_ETH device can't be used any more for DT accessing.

This patch adds additional ofnode node field to struct phy_device which can
be set explicitly by network drivers and used by PHY drivers, so
overwriting can be avoided. Also add helper function phy_get_ofnode()
which will check and return phy_device->node or dev_ofnode(phydev->dev) for
backward compatibility with existing drivers.

net: phy: Clean up includes of common.h

2018-07-26T19:08:22+00:00

We want to be able to include some other system headers in phy.h but
that requires us to have included common.h in the top-level first.

Also, common.h includes config.h as the first thing it does, so don't
include it directly.

Prepare for net: phy: prevent uclass_eth device "node" field overwriting
Prepare for [1] so that it doesn't break the build for a bunch of
boards. There are a number of reasons this series broke the build
but none of them depend on changes in the series, so fix up those
situations ahead of applying that series.

net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap

2018-07-26T19:08:21+00:00

The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then bit[7] of Configuration Register 4 (address 0x0031) must
be cleared to 0. This is to ensure proper operation of PHY.

Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property to advertise this and
allow corrective action in software.

net: phy: mv88e61xx: Force CPU port link up

2018-06-13T18:54:17+00:00

When connecting to from a CPU direct to a 88e6097 typically RGMII is
used. In order for traffic to actually pass we need to force the link up
so the CPU MAC on the other end will see the link.

net/phy/cortina: Add support for CS4223 PHY

2018-06-13T18:54:15+00:00

Add support for Cortina CS4223 10G PHY
  - As per the CS4223 specs, an EEPROM module is
    connected to the PHY. At startup the PHY reads
    the firmware line and tries to load the firmware
    into the internal memory.
  - This driver reads the EEPROM status
    and checks if firmware has been loaded

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.
