dt-bindings: mtd: drop mtd/cortina,gemini-flash.txt 



Drop mtd/cortina,gemini-flash.txt since it is nearly already handled by
Documentation/devicetree/bindings/mtd/mtd-physmap.yaml.

We add jedec-flash to list of compatible because one board (gemini-dlink-dns-313.dts) needs it.
See commit a10d862e ("ARM: dts: Fix the DNS-313 flash compatible")
The flash on the DNS-313 needs to be probed as JEDEC, it does not conform to the common CFI standard.

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>;

};
