| Linear Technology LTC2632/2634/2636 DAC |
| |
| Required properties: |
| - compatible: Has to contain one of the following: |
| lltc,ltc2632-l12 |
| lltc,ltc2632-l10 |
| lltc,ltc2632-l8 |
| lltc,ltc2632-h12 |
| lltc,ltc2632-h10 |
| lltc,ltc2632-h8 |
| lltc,ltc2634-l12 |
| lltc,ltc2634-l10 |
| lltc,ltc2634-l8 |
| lltc,ltc2634-h12 |
| lltc,ltc2634-h10 |
| lltc,ltc2634-h8 |
| lltc,ltc2636-l12 |
| lltc,ltc2636-l10 |
| lltc,ltc2636-l8 |
| lltc,ltc2636-h12 |
| lltc,ltc2636-h10 |
| lltc,ltc2636-h8 |
| |
| Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt |
| apply. In particular, "reg" and "spi-max-frequency" properties must be given. |
| |
| Optional properties: |
| - vref-supply: Phandle to the external reference voltage supply. This should |
| only be set if there is an external reference voltage connected to the VREF |
| pin. If the property is not set the internal reference is used. |
| |
| Example: |
| |
| vref: regulator-vref { |
| compatible = "regulator-fixed"; |
| regulator-name = "vref-ltc2632"; |
| regulator-min-microvolt = <1250000>; |
| regulator-max-microvolt = <1250000>; |
| regulator-always-on; |
| }; |
| |
| spi_master { |
| dac: ltc2632@0 { |
| compatible = "lltc,ltc2632-l12"; |
| reg = <0>; /* CS0 */ |
| spi-max-frequency = <1000000>; |
| vref-supply = <&vref>; /* optional */ |
| }; |
| }; |
