Subject: [PATCH 00/11] Add support for software nodes to gpiolib

This series attempts to add support for software nodes to gpiolib, using
software node references that were introduced recently. This allows us
to convert more drivers to the generic device properties and drop
support for custom platform data:

static const struct software_node gpio_bank_b_node = {
|-------.name = "B",
};

static const struct property_entry simone_key_enter_props[] = {
|-------PROPERTY_ENTRY_U32("linux,code", KEY_ENTER),
|-------PROPERTY_ENTRY_STRING("label", "enter"),
|-------PROPERTY_ENTRY_REF("gpios", &gpio_bank_b_node, 123, GPIO_ACTIVE_LOW),
|-------{ }
};

If we agree in principle, I would like to have the very first 3 patches
in an immutable branch off maybe -rc8 so that it can be pulled into
individual subsystems so that patches switching various drivers to
fwnode_gpiod_get_index() could be applied.

Thanks,
Dmitry

Dmitry Torokhov (11):
  gpiolib: of: add a fallback for wlf,reset GPIO name
  gpiolib: introduce devm_fwnode_gpiod_get_index()
  gpiolib: introduce fwnode_gpiod_get_index()
  net: phylink: switch to using fwnode_gpiod_get_index()
  net: mdio: switch to using fwnode_gpiod_get_index()
  drm/bridge: ti-tfp410: switch to using fwnode_gpiod_get_index()
  gpliolib: make fwnode_get_named_gpiod() static
  gpiolib: of: tease apart of_find_gpio()
  gpiolib: of: tease apart acpi_find_gpio()
  gpiolib: consolidate fwnode GPIO lookups
  gpiolib: add support for software nodes
