Subject: [PATCH v3 17/25] dt-bindings: panel: Add Bananapi S070WV20-CT16 ICN6211 MIPI-DSI to RGB bridge
Date: Fri, 26 Oct 2018 20:13:36 +0530 [thread overview]
Message-ID: <20181026144344.27778-18-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181026144344.27778-1-jagan@amarulasolutions.com>
Bananapi S070WV20-CT16 ICN6211 is 800x480, 4-lane MIPI-DSI to RGB
bridge panel, which is available on same PCB with 24-bit RGB interface.
So, this patch adds DSI specific binding details on existing
dt-bindings file.
Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

Changes for v3:
- Use existing binding doc and update dsi details
Changes for v2:
- none

Banana Pi 7" (S070WV20-CT16) TFT LCD Panel
+S070WV20-CT16 is 7" 800x480 panel connected through a 24-bit RGB interface.
+
+Depending on the variant, the PCB attached to the panel module either
+supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via
+an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel
+itself
+
Required properties:
-- compatible: should be "bananapi,s070wv20-ct16"
+- compatible:
+ for 24-bit RGB interface, use "bananapi,s070wv20-ct16"
+ for ICN6211 MIPI-DSI to RGB bridge, use "bananapi,s070wv20-ct16-icn6211"
+
+Required properties for RGB:
- power-supply: see ./panel-common.txt
+Required properties for MIPI-DSI to RGB:
+- reg: for DSI virtual channel used by that screen
+- avdd-supply: analog regulator dc1 switch
+- dvdd-supply: 3v3 digital regulator
+- reset-gpios: a GPIO phandle for the reset pin
+
Optional properties:
-- enable-gpios: see ./simple-panel.txt
+- enable-gpios: see ./simple-panel.txt(not available in MIPI-DSI to RGB bridge)
- backlight: see ./simple-panel.txt
This binding is compatible with the simple-panel binding, which is specified
in ./simple-panel.txt.
+
+Example:
+panel@0 {
+ compatible = "bananapi,s070wv20-ct16-icn6211";
+ reg = <0>;
+ avdd-supply = <®_dc1sw>;
+ dvdd-supply = <®_dldo1>;
+ reset-gpios = <&pio 3 6 GPIO_ACTIVE_HIGH>; /* PD6 */
+ backlight = <&backlight_dsi>;
+};
