Subject: [PATCH v2 0/4] Ethernet PHY reset GPIO updates for Amlogic SoCs

While trying to add the Ethernet PHY interrupt on the X96 Max I found
that the current reset line definition is incorrect. Patch #1 fixes
this.

Since the fix requires moving from the deprecated "snps,reset-gpio"
property to the generic Ethernet PHY reset bindings I decided to move
all Amlogic boards over to the non-deprecated bindings. That's what
patches #2 and #3 do.

Finally I found that Odroid-N2 doesn't define the Ethernet PHY's reset
GPIO yet. I don't have that board so I can't test whether it really
works but based on the schematics it should. 

This series is a partial successor to "stmmac: honor the GPIO flags
for the PHY reset GPIO" from [0]. I decided not to take Linus W.'s
Reviewed-by from patch #4 of that series because I had to change the
wording and I want to be sure that he's happy with that now.

One quick note regarding patches #1 and #4: I decided to violate the
"max 80 characters per line" (by 4 characters) limit because I find
that the result is easier to read then it would be if I split the
line.


Changes since v1 at [1]:
- fixed the reset deassert delay for RTL8211F PHYs - spotted by Robin
  Murphy (thank you). according to the public RTL8211E datasheet the
  correct values seem to be: 10ms assert, 30ms deassert
- fixed the reset assert and deassert delays for IP101GR PHYs. There
  are two values given in the public datasheet, use the higher one
  (10ms instead of 2.5)
- update the patch descriptions to quote the datasheets (the RTL8211F
  quotes are taken from the public RTL8211E datasheet because as far
  as I can tell the reset sequence is identical on both PHYs)
