[PATCH net-next 0/3] net: phy: dap8211r: add LED hardware control

[Artem Shimko <a.shimko.dev@gmail.com>]

Hello,

This series adds support for hardware-controlled LEDs on the DAP8211R
Gigabit Ethernet PHY.

The first patch documents the optional "leds" node in the Device Tree
binding. The second patch introduces a small helper to write extended
registers, since the LED registers are accessed indirectly via
EXT_ADD/EXT_DATA. The third patch implements the three LED callbacks
required by the PHY library.

$ make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/dptel,dap8211r.yaml
  SCHEMA  Documentation/devicetree/bindings/processed-schema.json

  DTEX    Documentation/devicetree/bindings/net/dptel,dap8211r.example.dts
  DTC [C] Documentation/devicetree/bindings/net/dptel,dap8211r.example.dtb

Required:
CONFIG_NEW_LEDS=y
    CONFIG_LEDS_CLASS=y
    CONFIG_LEDS_TRIGGERS=y
        CONFIG_LEDS_TRIGGER_NETDEV=y

Testing:
$ ip link set eth1 up
$ ls /sys/class/leds/
stmmac-1:01:amber:lan  stmmac-1:01:green:lan
$ echo eth1 > /sys/class/leds/stmmac-1:01:green:lan/device_name
$ echo 1 > /sys/class/leds/stmmac-1:01:green:lan/link_1000
$ cat /sys/class/leds/stmmac-1:01:green:lan/offloaded

$ echo eth1 > /sys/class/leds/stmmac-1:01:amber:lan/device_name
$ echo 1 > /sys/class/leds/stmmac-1:01:amber:lan/tx
$ echo 1 > /sys/class/leds/stmmac-1:01:amber:lan/rx
$ cat /sys/class/leds/stmmac-1:01:amber:lan/offloaded

$ ip addr add PEER_IP_ADDR dev eth1
$ ping -I eth1 ELP_ID_ADDR
