This patch adds support for positioning of the FB windows on the LCD screen.
This patchset creates an ioctl and defines a data structure which are
specific to samsung SOCs, to hold the window position.
Just as a note, there are many drivers like mx3fb.c, au1200fb.c and OMAP
seem to be doing window/plane positioning in their driver code.
Is it possible to have this window positioning support at a common place?
For instance, we can have a common struture and ioctl number in
include/linux/fb.h as below:
#define FBIOPOS_OVERLAY_WIN _IOW('F', 0x21, struct fb_overlay_win_pos)
struct fb_overlay_win_pos {
__u32 win_pos_x; /* x-offset of window from LCD(0,0) */
__u32 win_pos_y; /* y-offset of window from LCD(0,0) */
};
where LCD(0,0) means the first pixel of the LCD screen.
Individual drivers can have implementation for this ioctl.
