+Mitsubishi "AA070MC01 7.0" WVGA TFT LCD panel
+
+Required properties:
+- compatible: should be "mitsubishi,aa070mc01-ca1"
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
--- /dev/null
+Tianma Micro-electronics TM070RVHG71 7.0" WXGA TFT LCD panel
+
+Required properties:
+- compatible: should be "tianma,tm070rvhg71"
+- power-supply: single regulator to provide the supply voltage
+- backlight: phandle of the backlight device attached to the panel
+
+Required nodes:
+- port: LVDS port mapping to connect this display
+
+This panel needs single power supply voltage. Its backlight is conntrolled
+via PWM signal.
+
+Example:
+--------
+
+Example device-tree definition when connected to iMX6Q based board
+
+ panel: panel-lvds0 {
+ compatible = "tianma,tm070rvhg71";
+ backlight = <&backlight_lvds>;
+ power-supply = <®_lvds>;
+
+ port {
+ panel_in_lvds0: endpoint {
+ remote-endpoint = <&lvds0_out>;
+ };
+ };
+ };
Required properties:
- compatible: value should be one of the following
"rockchip,rk3036-vop";
+ "rockchip,rk3126-vop";
"rockchip,rk3288-vop";
"rockchip,rk3368-vop";
"rockchip,rk3366-vop";
- "lcd" for the clock feeding the output pixel clock & IP clock.
- resets: reset to be used by the device (defined by use of RCC macro).
Required nodes:
- - Video port for RGB output.
+ - Video port for DPI RGB output: ltdc has one video port with up to 2
+ endpoints:
+ - for external dpi rgb panel or bridge, using gpios.
+ - for internal dpi input of the MIPI DSI host controller.
+ Note: These 2 endpoints cannot be activated simultaneously.
* STMicroelectronics STM32 DSI controller specific extensions to Synopsys
DesignWare MIPI DSI host controller
now have DRM_DEV_* variants of the drm print macros, so we can start to convert
those drivers back to using drm-formwatted specific log messages.
+Before you start this conversion please contact the relevant maintainers to make
+sure your work will be merged - not everyone agrees that the DRM dmesg macros
+are better.

This option enables the framework for buffer-sharing between
multiple drivers. A buffer is associated with a file using driver

* 2. Userspace passes this file-descriptors to all drivers it wants this buffer
* to share with: First the filedescriptor is converted to a &dma_buf using
- * dma_buf_get(). The the buffer is attached to the device using
+ * dma_buf_get(). Then the buffer is attached to the device using
* dma_buf_attach().
*
* Up to this stage the exporter is still free to migrate or reallocate the
* backing storage.
*
- * 3. Once the buffer is attached to all devices userspace can inniate DMA
+ * 3. Once the buffer is attached to all devices userspace can initiate DMA
* access to the shared buffer. In the kernel this is done by calling
* dma_buf_map_attachment() and dma_buf_unmap_attachment().
*
* Returns sg_table containing the scatterlist to be returned; returns ERR_PTR
* on error. May return -EINTR if it is interrupted by a signal.
*
- * A mapping must be unmapped again using dma_buf_map_attachment(). Note that
+ * A mapping must be unmapped by using dma_buf_unmap_attachment(). Note that
* the underlying backing storage is pinned for as long as a mapping exists,
* therefore users/importers should not hold onto a mapping for undue amounts of
