Subject: [PATCH 1/7] dt-bindings: mfd: ds90ux9xx: add description of TI DS90Ux9xx ICs
Date: Tue, 9 Oct 2018 00:11:59 +0300 [thread overview]
Message-ID: <20181008211205.2900-2-vz@mleia.com> (raw)
In-Reply-To: <20181008211205.2900-1-vz@mleia.com>
From: Sandeep Jain <Sandeep_Jain@mentor.com>
The change adds device tree binding description of TI DS90Ux9xx
series of serializer and deserializer controllers which support video,
audio and control data transmission over FPD-III Link connection.

+Texas Instruments DS90Ux9xx de-/serializer controllers
+
+Required properties:
+- compatible: Must contain a generic "ti,ds90ux9xx" value and
+ may contain one more specific value from the list:
+ "ti,ds90ub925q",
+ "ti,ds90uh925q",
+ "ti,ds90ub927q",
+ "ti,ds90uh927q",
+ "ti,ds90ub926q",
+ "ti,ds90uh926q",
+ "ti,ds90ub928q",
+ "ti,ds90uh928q",
+ "ti,ds90ub940q",
+ "ti,ds90uh940q".
+
+Optional properties:
+- reg : Specifies the I2C slave address of a local de-/serializer.
+- power-gpios : GPIO line to control supplied power to the device.
+- ti,backward-compatible-mode : Overrides backward compatibility mode.
+ Possible values are "<1>" or "<0>".
+ If "ti,backward-compatible-mode" is not mentioned, the backward
+ compatibility mode is not touched and given by hardware pin strapping.
+- ti,low-frequency-mode : Overrides low frequency mode.
+ Possible values are "<1>" or "<0>".
+ If "ti,low-frequency-mode" is not mentioned, the low frequency mode
+ is not touched and given by hardware pin strapping.
+- ti,video-map-select-msb: Sets video bridge pins to MSB mode, if it is set
+ MAPSEL pin value is ignored.
+- ti,video-map-select-lsb: Sets video bridge pins to LSB mode, if it is set
+ MAPSEL pin value is ignored.
+- ti,pixel-clock-edge : Selects Pixel Clock Edge.
+ Possible values are "<1>" or "<0>".
+ If "ti,pixel-clock-edge" is High <1>, output data is strobed on the
+ Rising edge of the PCLK. If ti,pixel-clock-edge is Low <0>, data is
+ strobed on the Falling edge of the PCLK.
+ If "ti,pixel-clock-edge" is not mentioned, the pixel clock edge
+ value is not touched and given by hardware pin strapping.
+- ti,spread-spectrum-clock-generation : Spread Sprectrum Clock Generation.
+ Possible values are from "<0>" to "<7>". The same value will be
+ written to SSC register. If "ti,spread-spectrum-clock-gen" is not
+ found, then SSCG will be disabled.
+
+TI DS90Ux9xx serializers and deserializer device nodes may contain a number
+of children device nodes to describe and enable particular subcomponents
+found on ICs.
+
+Example:
+
+serializer: serializer@c {
+ compatible = "ti,ds90ub927q", "ti,ds90ux9xx";
+ reg = <0xc>;
+ power-gpios = <&gpio5 12 GPIO_ACTIVE_HIGH>;
+ ti,backward-compatible-mode = <0>;
+ ti,low-frequency-mode = <0>;
+ ti,pixel-clock-edge = <0>;
+ ...
+}
+
+deserializer: deserializer@3c {
+ compatible = "ti,ds90ub940q", "ti,ds90ux9xx";
+ reg = <0x3c>;
+ power-gpios = <&gpio6 31 GPIO_ACTIVE_HIGH>;
+ ...
+}
