-Ilitek ILI9322 TFT panel driver with SPI control bus
-
-This is a driver for 320x240 TFT panels, accepting a variety of input
-streams that get adapted and scaled to the panel. The panel output has
-960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
-VCOMH outputs.
-
-Required properties:
-  - compatible: "dlink,dir-685-panel", "ilitek,ili9322"
-    (full system-specific compatible is always required to look up configuration)
-  - reg: address of the panel on the SPI bus
-
-Optional properties:
-  - vcc-supply: core voltage supply, see regulator/regulator.txt
-  - iovcc-supply: voltage supply for the interface input/output signals,
-    see regulator/regulator.txt
-  - vci-supply: voltage supply for analog parts, see regulator/regulator.txt
-  - reset-gpios: a GPIO spec for the reset pin, see gpio/gpio.txt
-
-  The following optional properties only apply to RGB and YUV input modes and
-  can be omitted for BT.656 input modes:
-
-  - pixelclk-active: see display/panel/display-timing.txt
-  - de-active: see display/panel/display-timing.txt
-  - hsync-active: see display/panel/display-timing.txt
-  - vsync-active: see display/panel/display-timing.txt
-
-The panel must obey the rules for a SPI slave device as specified in
-spi/spi-bus.txt
-
-The device node can contain one 'port' child node with one child
-'endpoint' node, according to the bindings defined in
-media/video-interfaces.txt. This node should describe panel's video bus.
-
-Example:
-
-panel: display@0 {
-	compatible = "dlink,dir-685-panel", "ilitek,ili9322";
-	reg = <0>;
-	vcc-supply = <&vdisp>;
-	iovcc-supply = <&vdisp>;
-	vci-supply = <&vdisp>;
-
-	port {
-		panel_in: endpoint {
-			remote-endpoint = <&display_out>;
-		};

-SHARP LS037V7DW01 TFT-LCD panel
-===================================
-
-Required properties:
-- compatible: "sharp,ls037v7dw01"
-
-Optional properties:
-- label: a symbolic name for the panel
-- enable-gpios: a GPIO spec for the optional enable pin.
-  This pin is the INI pin as specified in the LS037V7DW01.pdf file.
-- reset-gpios: a GPIO spec for the optional reset pin.
-  This pin is the RESB pin as specified in the LS037V7DW01.pdf file.
-- mode-gpios: a GPIO
-  ordered MO, LR, and UD as specified in the LS037V7DW01.pdf file.
-
-Required nodes:
-- Video port for DPI input
-
-This panel can have zero to five GPIOs to configure to change configuration
-between QVGA and VGA mode and the scan direction. As these pins can be also
-configured with external pulls, all the GPIOs are considered optional with holes
-in the array.
-
-Example
--------
-
-Example when connected to a omap2+ based device:
-
-lcd0: display {
-	compatible = "sharp,ls037v7dw01";
-	power-supply = <&lcd_3v3>;
-	enable-gpios = <&gpio5 24 GPIO_ACTIVE_HIGH>;	/* gpio152, lcd INI */
-	reset-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>;	/* gpio155, lcd RESB */
-	mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH	/* gpio154, lcd MO */
-		      &gpio1 2 GPIO_ACTIVE_HIGH		/* gpio2, lcd LR */
-		      &gpio1 3 GPIO_ACTIVE_HIGH>;	/* gpio3, lcd UD */
-
-	port {
-		lcd_in: endpoint {
-			remote-endpoint = <&dpi_out>;
-		};

 The three main components of this are: (1) dma-buf, representing a
 sg_table and exposed to userspace as a file descriptor to allow passing
 between devices, (2) fence, which provides a mechanism to signal when
-one device as finished access, and (3) reservation, which manages the
+one device has finished access, and (3) reservation, which manages the
 shared or exclusive fence(s) associated with the buffer.
 
 Shared DMA Buffers

  - implements and manages operations in :c:type:`struct dma_buf_ops
    <dma_buf_ops>` for the buffer,
  - allows other users to share the buffer by using dma_buf sharing APIs,
