From 7325e0995f414af1cfa38be965dc47248cb4ec45 Mon Sep 17 00:00:00 2001 From: Xu Yang Date: Wed, 30 Apr 2025 17:45:00 +0800 Subject: [PATCH] dt-bindings: phy: imx8mq-usb: add imx95 tuning support The parameter value of below 3 properties are USB PHY specific. i.MX8MP and i.MX95 USB PHY has different meanings. This will enlarge parameters value and add constraints for them. - fsl,phy-tx-vref-tune-percent - fsl,phy-tx-rise-tune-percent - fsl,phy-comp-dis-tune-percent Reviewed-by: Jun Li Signed-off-by: Xu Yang Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250430094502.2723983-2-xu.yang_2@nxp.com Signed-off-by: Vinod Koul --- .../bindings/phy/fsl,imx8mq-usb-phy.yaml | 34 +++++++++++++++++-- 1 file changed, 31 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml b/Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml index c468207eb951..22dd91591a09 100644 --- a/Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml +++ b/Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml @@ -43,15 +43,15 @@ properties: fsl,phy-tx-vref-tune-percent: description: Tunes the HS DC level relative to the nominal level - minimum: 94 + minimum: 90 maximum: 124 fsl,phy-tx-rise-tune-percent: description: Adjusts the rise/fall time duration of the HS waveform relative to its nominal value - minimum: 97 - maximum: 103 + minimum: 90 + maximum: 120 fsl,phy-tx-preemp-amp-tune-microamp: description: @@ -111,6 +111,34 @@ allOf: reg: maxItems: 1 + - if: + properties: + compatible: + enum: + - fsl,imx8mq-usb-phy + - fsl,imx8mp-usb-phy + then: + properties: + fsl,phy-tx-vref-tune-percent: + minimum: 94 + fsl,phy-tx-rise-tune-percent: + minimum: 97 + maximum: 103 + + - if: + properties: + compatible: + contains: + enum: + - fsl,imx95-usb-phy + then: + properties: + fsl,phy-tx-vref-tune-percent: + maximum: 108 + fsl,phy-comp-dis-tune-percent: + minimum: 94 + maximum: 104 + - if: required: - orientation-switch -- 2.47.3
