From: David Daney <david.daney@xxxxxxxxxx>
As per the Subject, given a device tree fragment like this:
spi@1070000001000 {
compatible = "cavium,octeon-3010-spi";
reg = <0x10700 0x00001000 0x0 0x100>;
interrupts = <0 58>;
#address-cells = <1>;
#size-cells = <0>;
eeprom@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.
