The function returns a pointer to a structure describing a format based
on its fourcc. Use the function where applicable instead of hardcoded

The LCDC fb_info structure is only used to retrieve the default video

Instead of accessing the LCDC channel and fb_info structures directly,
use the LCDC notification callback to inform the LCDC driver about
display-related events.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The callback implements 3 notification events:
- SH_MOBILE_LCDC_EVENT_DISPLAY_CONNECT notifies the LCDC that the
display has been connected
- SH_MOBILE_LCDC_EVENT_DISPLAY_DISCONNECT notifies the LCDC that the
display has been disconnected
- SH_MOBILE_LCDC_EVENT_DISPLAY_MODE notifies that LCDC that a display
mode has been detected

As check_var already ensures that the mode is valid there is no need
to do those expensive lookups here again. The only thing that might
change is that the deprecated interface could report slightly
different refresh rates due to rounding errors.

This patch converts the modetables used in viafb to
- remove the strange thing that sync_end and blanking_end contained
the length and not the absolute value
- remove hundreds of useless defines
- use fb_videomode and not our own definition so modes defined in
the subsystem and received via EDID are compatible with ours
As the modes are now stored in a flat structure and no longer in a
tree like thing the lookup time was increased but as it is a rare
event anyway it shouldn't matter. Otherwise the behaviour should be
the same as before.

wait_pending_extra_info_updates() currently does a hacky second check
for extra_info_update_ongoing() at the end of the function to show a
warning if extra_info update is still ongoing. The call to
extra_info_update_ongoing() should really be inside spinlock, but that's
a bit heavy just for verification.
Rather than that, check the return value of the
wait_for_completion_timeout() and print an error if it has timeouted or
returned an error.
Even better would be to return the error value and act on it in the
callers of wait_pending_extra_info_updates. However, it's not clear what
the callers should do in case of an error, as the error should only
happen if there's a bug in the driver or the HW. So we'll just print the
warning for now.

While calculating regm and regmf value add using M2 divider in
the equation.
Formula for calculating:
Output clock on digital core domain:
CLKOUT = (M / (N+1))*CLKINP*(1/M2)
Internal oscillator output clock on internal LDO domain:
CLKDCOLDO = (M / (N+1))*CLKINP
The current code when allows variable M2 values as input
ignores using M2 divider values in calculation of regm and regmf.
so fix it by using M2 in calculation although the default value for
M2 is 1.

This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5
and adds extended timing control setting.
EXYNOS5 FIMD needs extended setting for video timing control.
Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and
VIDOSDxB registers in order to set timing value for lager resolution.
Also, address offset of VIDTCONx registers is changed from 0x0
to 0x20000, thus variable type should be changed to int type
to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.
