This patch converts (and removes it) this file to fsl,imx28-saif.yaml. Changes for the mxs-saif.txt: - Adds 'clocks', '#clock-cells' and '#sound-dai-cells' properties - Provide device description Signed-off-by: Lukasz Majewski Reviewed-by: Conor Dooley --- Changes for v4: - Change file name to match compatible (fsl,imx28-saif.yaml) - Remove 'saif0' and 'saif1' labels as those are not needed in the example node Changes for v3: - Add #clock-cells property Changes for v2: - Remove mxs-saif.txt - Add description with information about extensions required for this device's current DTS description --- .../bindings/sound/fsl,imx28-saif.yaml | 82 +++++++++++++++++++ .../devicetree/bindings/sound/mxs-saif.txt | 41 ---------- 2 files changed, 82 insertions(+), 41 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/fsl,imx28-saif.yaml delete mode 100644 Documentation/devicetree/bindings/sound/mxs-saif.txt diff --git a/Documentation/devicetree/bindings/sound/fsl,imx28-saif.yaml b/Documentation/devicetree/bindings/sound/fsl,imx28-saif.yaml new file mode 100644 index 000000000000..b2c73a9b7a55 --- /dev/null +++ b/Documentation/devicetree/bindings/sound/fsl,imx28-saif.yaml @@ -0,0 +1,82 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/sound/fsl,imx28-saif.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale MXS Serial Audio Interface (SAIF) + +maintainers: + - Lukasz Majewski + +allOf: + - $ref: dai-common.yaml# + +description: + The SAIF is based on I2S module that is used to communicate with audio codecs, + but only with half-duplex manner (i.e. it can either transmit or receive PCM + audio). + +properties: + compatible: + const: fsl,imx28-saif + + reg: + maxItems: 1 + + "#sound-dai-cells": + const: 0 + + interrupts: + maxItems: 1 + + dmas: + maxItems: 1 + + dma-names: + const: rx-tx + + "#clock-cells": + description: Configure the I2S device as MCLK clock provider. + const: 0 + + clocks: + maxItems: 1 + + fsl,saif-master: + description: Indicate that saif is a slave and its phandle points to master + $ref: /schemas/types.yaml#/definitions/phandle + +required: + - compatible + - reg + - "#sound-dai-cells" + - interrupts + - dmas + - dma-names + - clocks + +unevaluatedProperties: false + +examples: + - | + saif@80042000 { + compatible = "fsl,imx28-saif"; + reg = <0x80042000 2000>; + #sound-dai-cells = <0>; + interrupts = <59>; + dmas = <&dma_apbx 4>; + dma-names = "rx-tx"; + #clock-cells = <0>; + clocks = <&clks 53>; + }; + saif@80046000 { + compatible = "fsl,imx28-saif"; + reg = <0x80046000 2000>; + #sound-dai-cells = <0>; + interrupts = <58>; + dmas = <&dma_apbx 5>; + dma-names = "rx-tx"; + clocks = <&clks 53>; + fsl,saif-master = <&saif0>; + }; diff --git a/Documentation/devicetree/bindings/sound/mxs-saif.txt b/Documentation/devicetree/bindings/sound/mxs-saif.txt deleted file mode 100644 index 7ba07a118e37..000000000000 --- a/Documentation/devicetree/bindings/sound/mxs-saif.txt +++ /dev/null @@ -1,41 +0,0 @@ -* Freescale MXS Serial Audio Interface (SAIF) - -Required properties: -- compatible: Should be "fsl,-saif" -- reg: Should contain registers location and length -- interrupts: Should contain ERROR interrupt number -- dmas: DMA specifier, consisting of a phandle to DMA controller node - and SAIF DMA channel ID. - Refer to dma.txt and fsl-mxs-dma.txt for details. -- dma-names: Must be "rx-tx". - -Optional properties: -- fsl,saif-master: phandle to the master SAIF.
