These bindings model the device as an MFD, and support the GPIO expander and PWM functions. These bindings support the GPIO and PWM functions. Drop the existing adi,adp5585 and adi,adp5585-02 compatible strings from trivial-devices.yaml. They have been added there by mistake as the driver that was submitted at the same time used different compatible strings. We can take them over safely. Reviewed-by: Krzysztof Kozlowski Signed-off-by: Laurent Pinchart --- I've limited the bindings to GPIO and PWM as I lack hardware to design, implement and test the rest of the features the chip supports. Changes since v5: - Fix gpio-reserved-ranges definition Changes since v4: - Drop the right comment in trivial-devices.yaml Changes since v3: - Fix prefix and drop redundant text in subject line - Rename node in example from mfd@ to io-expander@ Changes since v2: - Drop gpio property from required - Drop second example Changes since v1: - Squash "dt-bindings: trivial-devices: Drop adi,adp5585 and adi,adp5585-02" into this patch - Merge child nodes into parent node --- .../devicetree/bindings/mfd/adi,adp5585.yaml | 92 +++++++++++++++++++ .../devicetree/bindings/trivial-devices.yaml | 4 - MAINTAINERS | 7 ++ 3 files changed, 99 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/adi,adp5585.yaml diff --git a/Documentation/devicetree/bindings/mfd/adi,adp5585.yaml b/Documentation/devicetree/bindings/mfd/adi,adp5585.yaml new file mode 100644 index 000000000000..f9c069f8534b --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/adi,adp5585.yaml @@ -0,0 +1,92 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/adi,adp5585.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Analog Devices ADP5585 Keypad Decoder and I/O Expansion + +maintainers: + - Laurent Pinchart + +description: + The ADP5585 is a 10/11 input/output port expander with a built in keypad + matrix decoder, programmable logic, reset generator, and PWM generator. + +properties: + compatible: + items: + - enum: + - adi,adp5585-00 # Default + - adi,adp5585-01 # 11 GPIOs + - adi,adp5585-02 # No pull-up resistors by default on special pins + - adi,adp5585-03 # Alternate I2C address + - adi,adp5585-04 # Pull-down resistors on all pins by default + - const: adi,adp5585 + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + vdd-supply: true + + gpio-controller: true + + '#gpio-cells': + const: 2 + + gpio-reserved-ranges: true + + "#pwm-cells": + const: 3 + +required: + - compatible + - reg + - gpio-controller + - "#gpio-cells" + - "#pwm-cells" + +allOf: + - if: + properties: + compatible: + contains: + const: adi,adp5585-01 + then: + properties: + gpio-reserved-ranges: false + else: + properties: + gpio-reserved-ranges: + maxItems: 1 + items: + items: + - const: 5 + - const: 1 + +additionalProperties: false + +examples: + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + io-expander@34 { + compatible = "adi,adp5585-00", "adi,adp5585"; + reg = <0x34>; + + vdd-supply = <®_3v3>; + + gpio-controller; + #gpio-cells = <2>; + gpio-reserved-ranges = <5 1>; + + #pwm-cells = <3>; + }; + }; + +... diff --git a/Documentation/devicetree/bindings/trivial-devices.yaml b/Documentation/devicetree/bindings/trivial-devices.yaml index 0a419453d183..8a6056323545 100644 --- a/Documentation/devicetree/bindings/trivial-devices.yaml +++ b/Documentation/devicetree/bindings/trivial-devices.yaml @@ -38,10 +38,6 @@ properties: - ad,adm9240 # AD5110 - Nonvolatile Digital Potentiometer - adi,ad5110 - # Analog Devices ADP5585 Keypad Decoder and I/O Expansion - - adi,adp5585 - # Analog Devices ADP5585 Keypad Decoder and I/O Expansion with support for Row5 - - adi,adp5585-02 # Analog Devices ADP5589 Keypad Decoder and I/O Expansion - adi,adp5589 # Analog Devices LT7182S Dual Channel 6A, 20V PolyPhase Step-Down Silent Switcher diff --git a/MAINTAINERS b/MAINTAINERS index 958e935449e5..4fe8bd8752a5 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -526,6 +526,13 @@ F: drivers/leds/leds-adp5520.c F: drivers/mfd/adp5520.c F: drivers/video/backlight/adp5520_bl.c +ADP5585 GPIO EXPANDER, PWM AND KEYPAD CONTROLLER DRIVER +M: Laurent Pinchart +L: linux-gpio@vger.kernel.org +L: linux-pwm@vger.kernel.org +S: Maintained +F: Documentation/devicetree/bindings/*/adi,adp5585*.yaml + ADP5588 QWERTY KEYPAD AND IO EXPANDER DRIVER (ADP5588/ADP5587) M: Michael Hennerich S: Supported
