This converts the Melfas MMS114 bindings and extend like this: - Require nodename touchscreen@ (this seems to be the case for all in-tree DTS files) - Add the mms134s and mms136 compatibles - Add the avdd and vdd power supplies - Define the I2C clock frequency property Cc: devicetree@xxxxxxxxxxxxxxx Cc: Stephan Gerhold <stephan@xxxxxxxxxxx> Cc: Simon Shields <simon@xxxxxxxxxxxxx> Cc: Tomasz Figa <tfiga@xxxxxxxxxxxx> Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx> --- .../input/touchscreen/melfas,mms114.yaml | 87 +++++++++++++++++++ .../bindings/input/touchscreen/mms114.txt | 42 --------- 2 files changed, 87 insertions(+), 42 deletions(-) create mode 100644 Documentation/devicetree/bindings/input/touchscreen/melfas,mms114.yaml delete mode 100644 Documentation/devicetree/bindings/input/touchscreen/mms114.txt diff --git a/Documentation/devicetree/bindings/input/touchscreen/melfas,mms114.yaml b/Documentation/devicetree/bindings/input/touchscreen/melfas,mms114.yaml new file mode 100644 index 000000000000..62366886fb3e --- /dev/null +++ b/Documentation/devicetree/bindings/input/touchscreen/melfas,mms114.yaml @@ -0,0 +1,87 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/input/touchscreen/melfas,mms114.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Melfas MMS114 family touchscreen controller bindings + +maintainers: + - Linus Walleij <linus.walleij@xxxxxxxxxx> + +allOf: + - $ref: touchscreen.yaml# + +properties: + $nodename: + pattern: "^touchscreen(@.*)?$" + + compatible: + items: + - enum: + - melfas,mms114 + - melfas,mms134s + - melfas,mms136 + - melfas,mms152 + - melfas,mms345l + + reg: + description: I2C address + + clock-frequency: + description: I2C client clock frequency, defined for host + minimum: 100000 + maximum: 400000 + + interrupts: + maxItems: 1 + + avdd-supply: + description: Analog power supply regulator on AVDD pin + + vdd-supply: + description: Digital power supply regulator on VDD pin + + touchscreen-size-x: true + touchscreen-size-y: true + touchscreen-fuzz-x: true + touchscreen-fuzz-y: true + touchscreen-fuzz-pressure: true + touchscreen-inverted-x: true + touchscreen-inverted-y: true + touchscreen-swapped-x-y: true + touchscreen-max-pressure: true + +additionalProperties: false + +required: + - compatible + - reg + - interrupts + - touchscreen-size-x + - touchscreen-size-y + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + i2c { + #address-cells = <1>; + #size-cells = <0>; + touchscreen@48 { + compatible = "melfas,mms114"; + reg = <0x48>; + interrupt-parent = <&gpio>; + interrupts = <39 IRQ_TYPE_EDGE_FALLING>; + avdd-supply = <&ldo1_reg>; + vdd-supply = <&ldo2_reg>; + touchscreen-size-x = <720>; + touchscreen-size-y = <1280>; + touchscreen-fuzz-x = <10>; + touchscreen-fuzz-y = <10>; + touchscreen-fuzz-pressure = <10>; + touchscreen-inverted-x; + touchscreen-inverted-y; + }; + }; + +... diff --git a/Documentation/devicetree/bindings/input/touchscreen/mms114.txt b/Documentation/devicetree/bindings/input/touchscreen/mms114.txt deleted file mode 100644 index 707234cfd7e6..000000000000 --- a/Documentation/devicetree/bindings/input/touchscreen/mms114.txt +++ /dev/null @@ -1,42 +0,0 @@ -* MELFAS MMS114/MMS152/MMS345L touchscreen controller - -Required properties: -- compatible: should be one of: - - "melfas,mms114" - - "melfas,mms152" - - "melfas,mms345l" -- reg: I2C address of the chip -- interrupts: interrupt to which the chip is connected -- touchscreen-size-x: See [1] -- touchscreen-size-y: See [1] - -Optional properties: -- touchscreen-fuzz-x: See [1] -- touchscreen-fuzz-y: See [1] -- touchscreen-fuzz-pressure: See [1] -- touchscreen-inverted-x: See [1] -- touchscreen-inverted-y: See [1] -- touchscreen-swapped-x-y: See [1] - -[1]: Documentation/devicetree/bindings/input/touchscreen/touchscreen.txt - -Example: - - i2c@00000000 { - /* ... */ - - touchscreen@48 { - compatible = "melfas,mms114"; - reg = <0x48>; - interrupts = <39 0>; - touchscreen-size-x = <720>; - touchscreen-size-y = <1280>; - touchscreen-fuzz-x = <10>; - touchscreen-fuzz-y = <10>; - touchscreen-fuzz-pressure = <10>; - touchscreen-inverted-x; - touchscreen-inverted-y; - }; - - /* ... */ - }; -- 2.29.2
