Philipp Tomsich 89b2b6186d rockchip: video: Kconfig: set MAX_XRES and MAX_YRES via Kconfig
This introduces two new Kconfig options that configure the maximum
allowable framebuffer size (i.e. the memory reservation/allocation for
the framebuffer):
 - VIDEO_ROCKCHIP_MAX_XRES
 - VIDEO_ROCKCHIP_MAX_YRES
The resulting memory allocation will cover 4 byte per pixel for these
resolutions.

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

Rockchip SoCs provide video output capabilities for High-Definition
Multimedia Interface (HDMI), Low-voltage Differential Signalling
(LVDS), embedded DisplayPort (eDP) and Display Serial Interface (DSI).
This driver supports the on-chip video output device, and targets the
Rockchip RK3288 and RK3399.
