2 # Video drivers selection for rockchip soc. These configs only impact the
3 # compile process. You can surely check all the options. In this case, all the
4 # display driver will be compiled, but which drivers finally will be used is
5 # decided by device tree configuration. What's more, enable needed power for
6 # display by configure the device tree, and the vop driver will do the rest.

11 menuconfig VIDEO_ROCKCHIP
12 bool "Enable Rockchip Video Support"
15 Rockchip SoCs provide video output capabilities for High-Definition
16 Multimedia Interface (HDMI), Low-voltage Differential Signalling
17 (LVDS), embedded DisplayPort (eDP) and Display Serial Interface (DSI).
19 This driver supports the on-chip video output device, and targets the
20 Rockchip RK3288 and RK3399.
22 config VIDEO_ROCKCHIP_MAX_XRES
23 int "Maximum horizontal resolution (for memory allocation purposes)"
24 depends on VIDEO_ROCKCHIP
27 The maximum horizontal resolution to support for the framebuffer.
28 This configuration is used for reserving/allocating memory for the
29 framebuffer during device-model binding/probing.
31 config VIDEO_ROCKCHIP_MAX_YRES
32 int "Maximum vertical resolution (for memory allocation purposes)"
33 depends on VIDEO_ROCKCHIP
36 The maximum vertical resolution to support for the framebuffer.
37 This configuration is used for reserving/allocating memory for the
38 framebuffer during device-model binding/probing.
42 config DISPLAY_ROCKCHIP_EDP
44 depends on VIDEO_ROCKCHIP
46 This enables Embedded DisplayPort(EDP) display support.
48 config DISPLAY_ROCKCHIP_LVDS
50 depends on VIDEO_ROCKCHIP
52 This enables Low-voltage Differential Signaling(LVDS) display
55 config DISPLAY_ROCKCHIP_HDMI
58 depends on VIDEO_ROCKCHIP
60 This enables High-Definition Multimedia Interface display support.
62 config DISPLAY_ROCKCHIP_MIPI
64 depends on VIDEO_ROCKCHIP
66 This enables Mobile Industry Processor Interface(MIPI) display
67 support. The mipi controller and dphy on rk3288& rk3399 support
68 16,18, 24 bits per pixel with up to 2k resolution ratio.
