f0b94c4bcd net: zynq_gem: Dont flush dummy descriptors
Dont flush dummy descriptors as they are already
allocated from a region with dcache off. Tested
this on Zynq(zc702) and ZynqMP(zcu102) boards.

dea004e41a net: zynq_gem: Use wait_for_bit with non breakable
Use wait_for_bit to be non breakable as using it with
breakable causes issue of un interruptible auto negotiation.
This is due to the ctrlc pressed will taken for wait_for_bit()
abort during phy_read() and hence not coming out of
auto negotiation.

b233089787 net: zynq_gem: Do not return -ENOSYS on success
The .read_rom_hwaddr net_ops hook does not check the return value, which
is why it was never caught that we are currently returning 0 if the
read_rom_hwaddr function return -ENOSYS and -ENOSYS otherwise.

In this case we can simplify this by just returning the result of the
function.

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.

2c2ab8d65f net: zynq_gem: Fix masking of supported phydev features
When the zynq_gem driver initializes the phy it sets the supported
features that the phy can support and advertise. However instead of
masking the supported features such that it limits the available
features it sets the phy to have the exact supported features of the
zynq_gem. This is problematic as it will enable features that a phy does
not have or cannot advertise.

Specifically this appears as an issue when using a phy that is only
capable of 10/100, but the zynq_gem driver will override this and try to
enable and advertise 10/100/1000.

15a2acdf85 common: miiphyutil: Work and report phy address in hex in mdio cmd
It is confusing that mdio commands work and report phy id as
decimal value when mii is working with hex values.

For example:
ZynqMP> mdio list
gem:
21 - TI DP83867 <--> ethernet@ff0e0000
ZynqMP> mdio read ethernet@ff0e0000 0
Reading from bus gem
PHY at address 21:
0 - 0x1140
ZynqMP> mii dump 21 0
Incorrect PHY address. Range should be 0-31
...
ZynqMP> mii dump 15
0.     (1140)                 -- PHY control register --
  (8000:0000) 0.15    =     0    reset

U-Boot normally takes hex values that's why this patch is changing mdio
command to handle hex instead of changing mii command to handle decimal
values.
