This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5

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.

The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen

monitor's native mode.

ovl->enable/disable are meant to be synchronous so that they can handle
the configuration of fifo sizes. The current kernel doesn't configure
fifo sizes yet, and so the code doesn't need to block to function (from
omapdss driver's perspective).

However, for the users of omapdss a non-blocking ovl->disable is
confusing, because they don't know when the memory area is not used
any more.

Furthermore, when the fifo size configuration is added in the next merge
window, the change from non-blocking to blocking could cause side
effects to the users of omapdss. So by making the functions block
already will keep them behaving in the same manner.

And, while not the main purpose of this patch, this will also remove the
compile warning:

For DSS clock domain to transition from idle to active state. It's necessary
to enable the optional clock DSS_FCLK before we enable the module using the
MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register.

This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led
to DSS clock domain not getting out of idle when pm_runtime_get_sync() was
called for hdmi's platform device.

Since the clock domain failed to change it's state to active, the hwmod code
disables any clocks it had enabled before for this hwmod. This led to the clock
'dss_48mhz_clk' gettind disabled.

When hdmi's runtime_resume() op is called, the call to dss_runtime_get()
correctly enables the DSS clock domain this time. However, the clock
'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was
disabled previously, the driver fails when it tries to enable HDMI's PHY.

Fix this for now by ensuring that dss_runtime_get() is called before we call
pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would
be to modify the DSS related hwmod's mainclks, and also some changes in how
opt clocks are handled in the DSS driver.

This fixes the issue of HDMI not working when it's the default display. The
issue is not seen if any other display is already enabled as the first display
would have correctly enabled the DSS clockdomain.

When a PMIC is not found, this driver is unable to obtain its
'vdds_dsi_reg' regulator.  Even through its initialization function
fails, other code still calls its enable function, which fails to
check whether it has this regulator before asking for it to be enabled.

This fixes the oops, however a better fix would be to sort out the
upper layers to prevent them calling into a module which failed to
initialize.

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

In au1100fb.c, the probe function now returns -ENODEV on failure.

The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.

The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.

To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

Before:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 remove   /2-1.2:1.0/graphics/fb0 (graphics)

After:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)

LCDC functional clock may or may not be derived from CPU/MPU DPLL,
For example,
AM335x => Separate independent DPLL for LCDC
Davinci => Same DPLL as MPU

So, on platforms where LCDC functional clock is not derived from CPU/MPU
PLL it is not required to reset LCDC module as its functional clock does
not change with DVFS.

This patch adds check to do reset only if functional clock changes
between pre and post notifier callbacks with DVFS.
