Convert the mtd-physmap binding to DT schema format. The arm-versatile, cypress,hyperflash and intel,ixp4xx-flash are all just an additional compatible string, so they are all merged into the main schema. There doesn't appear to be any users nor support for 'vendor-id' and 'device-id', so these have been dropped.

Flash device on Cortina Systems Gemini SoC
|
|
|
|
This flash is regular CFI compatible (Intel or AMD extended) flash chips with
|
|
some special bits that can be controlled by the machine's system controller.
|
|
|
|
Required properties:
|
|
- compatible : must be "cortina,gemini-flash", "cfi-flash";
|
|
- reg : memory address for the flash chip
|
|
- syscon : must be a phandle to the system controller
|
|
- bank-width : width in bytes of flash interface, should be <2>
|
|
|
|
For the rest of the properties, see mtd-physmap.yaml.
|
|
|
|
The device tree may optionally contain sub-nodes describing partitions of the
|
|
address space. See partition.txt for more detail.
|
|
|
|
Example:
|
|
|
|
flash@30000000 {
|
|
compatible = "cortina,gemini-flash", "cfi-flash";
|
|
reg = <0x30000000 0x01000000>;
|
|
syscon = <&syscon>;
|
|
bank-width = <2>;
|
|
};
