8f1a5ac797 net: dm: fec: Fix regulator enable when using DM_REGULATOR
When DM_REGULATOR is enabled, the driver attempts to call
regulator_autoset() which expects the regulators to be on at boot
and/or always on and fails if they are not true.
For a more generic approach, this patch just calls
regulator_set_enable() which shouldn't have such restrictions.

binding")

774ec60b74 Enable FEC driver to retrieve PHY address from device tree
Currently if we have more than one phy on the MDIO bus, we do not have a
good mechanism for determining which should be used at runtime. Enable the
FEC driver to determine the address for the PHY from the device tree.

331fcabe4f net: dm: fec: Fix phy-reset-duration clamping and defaults
The DT binding says:
- phy-reset-duration : Reset duration in milliseconds.  Should present
  only if property "phy-reset-gpios" is available.  Missing the property
  will have the duration be 1 millisecond.  Numbers greater than 1000 are
  invalid and 1 millisecond will be used instead.

However the current code:
 - clamps values greater than 1000ms to 1000ms rather than 1.
 - does not initialize the delay if the property does not exist
   (else clause mismatch)
 - returns an error if phy-reset-gpios is not defined

Fix all this and simplify by using dev_read_u32_default()

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

when one wants to set PHY ADDR on a iMX board (FEC + driver model).

This shall be changed to CONFIG_FEC_MXC_PHYADDR, as only when we do have

As a side effect, when CONFIG_FEC_MXC_PHYADDR is not set, we scan PHY bus
for connected PHY devices.

MDIO port. But Some boards share one MDIO port for the two enets. So
introduce a configuration CONFIG_FEC_MXC_MDIO_BASE to indicate
the MDIO port for sharing.
In Kconfig, user needs enable CONFIG_FEC_MXC_SHARE_MDIO first to enter
the CONFIG_FEC_MXC_MDIO_BASE.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

1221ce459d treewide: replace #include <asm/errno.h> with <linux/errno.h>
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

0750701a3f driver/net/fec: support fixed speed connection
If MAC is directly connected to another MAC (like a switch for example)
we don't need to probe for a phy, autoneogation and so on. We simply
have to setup speed.

845a57b4de net: fec_mxc: unregister mdio bus on probe error
If fecmxc_initialize_multi() fails, it frees but does not unregister
the mdio bus, causing subsequent uses of the "mii" command to crash.
Fix this by adding mdio_unregister() calls where needed.

843a3e5893 net: fec_mxc: configure MDIO hold time
If the host clock frequency is higher than 100 MHz, the MDIO hold
time needs to be increased from its current setting of one cycle in
order to meet the specified minium of 10 ns.  Writing an appropriate
value to the HOLDTIME field of the MII_SPEED register achieves this.

1fd92db83d net: cosmetic: Fix var naming net <-> eth drivers
Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.

This cleans up the temporary hacks that were added to this interface
along with the DM support.

This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).
