749c61e5b3 dt-bindings: net: micrel: add coma-mode-gpios property
The LAN8814 has a coma mode pin which is used to put the PHY into
isolate and power-down mode. Usually strapped to be asserted by default.
A GPIO is then used to take the PHY out of this mode.

b117c88df0 dt-bindings: net: micrel: Revert latency support and timestamping check
Revert latency support from binding.
Based on the discussion[1], the DT is the wrong place to have the
lantecies for the PHY.

77501a79ce net: phy: micrel: Add KSZ8041FTL fiber mode support
We can't detect the FXEN (fiber mode) bootstrap pin, so configure
it via a boolean device tree property "micrel,fiber-mode".
If it is enabled, auto-negotiation is not supported.
The only available modes are 100base-fx (full duplex and half duplex).

c3a8e1eddd dt/bindings: add clock-select function property to micrel phy binding
Add "micrel,rmii-reference-clock-select-25-mhz" to Micrel ethernet PHY
binding documentation.

This property is needed to properly describe some revisions of Micrel
PHYs which has the function of this configuration bit inverted so that
setting it enables 25 MHz rather than 50 MHz clock mode.

Note that a clock reference ("rmii-ref") is still needed to actually
select either mode.

6d01329444 dt/bindings: reformat micrel eth-phy documentation
Reduce indentation of Micrel PHY binding documentations somewhat.

Also fix "reference input clock" typo while at it.

86dc1342bc net: phy: micrel: add support for clock-mode select to KSZ8081/KSZ8091
Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select
bit, which is used to select 25 or 50 MHz clock mode.

Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of
this bit is inverted so that setting it enables 25 rather than 50 MHz
mode. Add a new device-tree property
"micrel,rmii-reference-clock-select-25-mhz" to describe this.

1fadee0c36 net/phy: micrel: Add clock support for KSZ8021/KSZ8031
The KSZ8021 and KSZ8031 support RMII reference input clocks of 25MHz
and 50MHz. Both PHYs differ in the default frequency they expect
after reset. If this differs from the actual input clock, then
register 0x1f bit 7 must be changed.

Add support for the led-mode property for the following PHYs
which have a single LED mode configuration value.

KSZ8001 and KSZ8041 which both use register 0x1e bits 15,14 and
KSZ8021, KSZ8031 and KSZ8051 which use register 0x1f bits 5,4
to control the LED configuration.
