From: Fabio Estevam <festevam@xxxxxxx> i.MX1 has three UART interrupts instead of a single one like other i.MX devices. Take this into account for properly describing the i.MX1 UART interrupts. This fixes the following dt-schema warning: imx1-ads.dtb: serial@206000: interrupts: [[30], [29], [26]] is too long from schema $id: http://devicetree.org/schemas/serial/fsl-imx-uart.yaml#yaml# Signed-off-by: Fabio Estevam <festevam@xxxxxxx> --- .../bindings/serial/fsl-imx-uart.yaml | 29 +++++++++++++++---- 1 file changed, 24 insertions(+), 5 deletions(-) diff --git a/Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml b/Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml index 83035553044a..9c6dc16f88a6 100644 --- a/Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml +++ b/Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml @@ -9,10 +9,6 @@ title: Freescale i.MX Universal Asynchronous Receiver/Transmitter (UART) maintainers: - Fabio Estevam <festevam@xxxxxxxxx> -allOf: - - $ref: serial.yaml# - - $ref: rs485.yaml# - properties: compatible: oneOf: @@ -68,7 +64,11 @@ properties: - const: tx interrupts: - maxItems: 1 + items: + - description: UART RX Interrupt + - description: UART TX Interrupt + - description: UART RTS Interrupt + minItems: 1 wakeup-source: true @@ -110,6 +110,25 @@ required: - clock-names - interrupts +allOf: + - $ref: serial.yaml# + - $ref: rs485.yaml# + + - if: + properties: + compatible: + contains: + const: fsl,imx1-uart + then: + properties: + interrupts: + minItems: 3 + maxItems: 3 + else: + properties: + interrupts: + maxItems: 1 + unevaluatedProperties: false examples: -- 2.34.1
