[PATCH 0/3] of/spi/eeprom: Configure at25 from device tree and autoload its driver.

[David Daney]

From: David Daney <david.daney at cavium.com>

As per the Subject, given a device tree fragment like this:

	spi at 1070000001000 {
		compatible = "cavium,octeon-3010-spi";
		reg = <0x10700 0x00001000 0x0 0x100>;
		interrupts = <0 58>;
		#address-cells = <1>;
		#size-cells = <0>;

		eeprom at 0 {
			compatible = "st,m95256", "atmel,at25";
			reg = <0>;
			spi-max-frequency = <5000000>;
			spi-cpha;
			spi-cpol;

			pagesize = <64>;
			size = <32768>;
			address-width = <16>;
		};
	};

The at25 module is autoloaded and configured from the device tree data.

1/3) Make of_modalias_node() work better for auto loading drivers.

2/3) Use MODALIAS prefixed with "spi:" for SPI drivers so modprobe can
     find the proper driver module.

3/3) Use standard eeprom device tree binding to configure at25,
     convert MODULE_ALIAS(), to equivalent MODULE_DEVICE_TABLE().

David Daney (3):
  of: Add prefix parameter to of_modalias_node().
  spi: Use consistent MODALIAS values.
  eeprom/of: Add device tree bindings to at25.
