[linux-nfc] [PATCH 3/7] dt-bindings: nfc: st,st21nfca: convert to dtschema

[Krzysztof Kozlowski]

Convert the ST ST21NFCA NFC controller to DT schema format.  The
conversion also adds a new required property - interrupts - because it
was missing in the old bindings by mistake.

-* STMicroelectronics : NFC Transceiver ST95HF
-
-ST NFC Transceiver is required to attach with SPI bus.
-ST95HF node should be defined in DT as SPI slave device of SPI
-master with which ST95HF transceiver is physically connected.
-The properties defined below are required to be the part of DT
-to include ST95HF transceiver into the platform.
-
-Required properties:
-===================
-- reg: Address of SPI slave "ST95HF transceiver" on SPI master bus.
-
-- compatible: should be "st,st95hf" for ST95HF NFC transceiver
-
-- spi-max-frequency: Max. operating SPI frequency for ST95HF
-	transceiver.
-
-- enable-gpio: GPIO line to enable ST95HF transceiver.
-
-- interrupts : Standard way to define ST95HF transceiver's out
-	interrupt.
-
-Optional property:
-=================
-- st95hfvin-supply : This is an optional property. It contains a
-	phandle to ST95HF transceiver's regulator supply node in DT.
-
-Example:
-=======
-spi@9840000 {
-	reg = <0x9840000 0x110>;
-	#address-cells = <1>;
-	#size-cells = <0>;
-	cs-gpios = <&pio0 4>;

I already sent a patch for this one.

I missed that new compatible. I'll send a patch adding nxp,nxp-nci-i2c
and try to fix the DTS (missing clock-frequency).

Hmm, this actually looks as mistake in bindings. First, clock-frequency
is a property of a I2C bus, not I2C child device. Second, it should not
be a required property anyway, as I2C will choose a default one matching
driver (e.g. standard speed of 100 kHz).

Except the trf7970a NFC driver, none of other NFC drivers parse the
clock-frequency.

Krzysztof
