The LTC2654 devices are 4-channel, 16-/12-bit DACs with an internal reference and SPI interface. They use the same 24-bit SPI command format as the LTC2632/2634/2636 family. The 16-bit variants (LTC2654-L16 and LTC2654-H16) require new compatible strings, as no existing compatibles support 16-bit resolution. The 12-bit variants (LTC2654-L12 and LTC2654-H12) are register- compatible with LTC2634-L12 and LTC2634-H12 respectively, and can use them as fallback compatibles. Changes added for: - lltc,ltc2654-l16: 16-bit, 2.5V internal reference - lltc,ltc2654-l12: 12-bit, 2.5V internal reference (fallback to lltc,ltc26= 34-l12) - lltc,ltc2654-h16: 16-bit, 4.096V internal reference - lltc,ltc2654-h12: 12-bit, 4.096V internal reference (fallback to lltc,ltc= 2634-h12) Signed-off-by: David Marinovic Acked-by: Conor Dooley --- .../bindings/iio/dac/lltc,ltc2632.yaml | 57 ++++++++++++------- 1 file changed, 35 insertions(+), 22 deletions(-) diff --git a/Documentation/devicetree/bindings/iio/dac/lltc,ltc2632.yaml b/= Documentation/devicetree/bindings/iio/dac/lltc,ltc2632.yaml index 733edc7d6d17..50a9cbb44e36 100644 --- a/Documentation/devicetree/bindings/iio/dac/lltc,ltc2632.yaml +++ b/Documentation/devicetree/bindings/iio/dac/lltc,ltc2632.yaml @@ -4,36 +4,49 @@ $id: http://devicetree.org/schemas/iio/dac/lltc,ltc2632.yaml# $schema: http://devicetree.org/meta-schemas/core.yaml# =20 -title: Linear Technology LTC263x 12-/10-/8-Bit Rail-to-Rail DAC +title: Linear Technology LTC263x and LTC2654 Rail-to-Rail DAC =20 maintainers: - Michael Hennerich =20 description: | - Bindings for the Linear Technology LTC2632/2634/2636 DAC - Datasheet can be found here: https://www.analog.com/media/en/technical-d= ocumentation/data-sheets/LTC263[246].pdf + Bindings for the Linear Technology LTC2632/2634/2636/2654 DAC + Datasheet can be found here: + https://www.analog.com/media/en/technical-documentation/data-sheets/LT= C263[246].pdf + https://www.analog.com/media/en/technical-documentation/data-sheets/26= 54f.pdf =20 properties: compatible: - enum: - - 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 + oneOf: + - enum: + - 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 + - lltc,ltc2654-l16 + - lltc,ltc2654-h16 + - items: + - enum: + - lltc,ltc2654-l12 + - const: lltc,ltc2634-l12 + - items: + - enum: + - lltc,ltc2654-h12 + - const: lltc,ltc2634-h12 =20 reg: maxItems: 1 --=20 2.50.1
