arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindings
The snps,reset-gpio bindings are deprecated in favour of the generic
"Ethernet PHY reset" bindings.
Replace snps,reset-gpio from the ðmac node with reset-gpios in the
ethernet-phy node. The old snps,reset-active-low property is now encoded
directly as GPIO flag inside the reset-gpios property.
snps,reset-delays-us is converted to reset-assert-us and
reset-deassert-us. reset-assert-us is the second cell from
snps,reset-delays-us while reset-deassert-us was the third cell.
Instead of blindly copying the old values (which seems strange since
they gave the PHY one second to come out of reset) over this also
updates the delays based on the datasheets:
- the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet
mentions: "For a complete PHY reset, this pin must be asserted low
for at least 10ms") and a 30ms deassert delay (the datasheet
mentions: "Wait for a further 30ms (for internal circuits settling
time) before accessing the PHY register". This applies to the
following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95
variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox
A1, GXM Q200, GXM RBox Pro boards.
- the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet
mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms
as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock
output ready after reset released | 10ms"). This applies to the GXBB
Nexbox A95X board.
- the Micrel KSZ9031 seems to require a 100us delay but use the same
(seemingly safe) values from RTL8211F due to lack of a board to verify
this. This applies to the GXBB P200 board.
The GXBB P201 board is left out from this conversion because it doesn't
have a dedicated PHY node (because it's not clear which PHY is used on
that board).
