V4L2 LCD device drivers?
I've seen several video capture V4L2 drivers in the mainline kernel...just trying to gain
some a grip on the arch between V4L2 and FB drivers..
I specifically have 2 qs:
1. Are there any V4L2 drivers for LCD panels?
Is there a tutorial/howto on writing them?
2. How exactly do V4L2 and FB (framebuffer) drivers fit together architecture-wise?
Or do they at all?
Is it the case that V4L2 drivers are (always/sometimes) layered above the fb driver? Any info
The v4l2 drivers are only for analog capture cards, and the tuner and audio chips found on some capture cards. If you want a driver for a LCD display panel (not a monitor), you need to find the driver based on the make of the LCD display.
I know nothing about framebuffers.
