[PATCH 0/2] video: s3c-fb: Add window positioning support

[Ajay Kumar <ajaykumar.rs@samsung.com>]

These patches are created against "for-next" branch of Kukjin Kim's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git

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.
