be stacked on top of a "real" block driver, and catches
all write operations on their way from the file systems
layer above to the real driver below, effectively shielding
the lower driver from those write accesses. The requests are
then diverted to an ordinary file, located somewhere else
(configurable). Later read requests are checked to see whether
they can be serviced by the "real" block driver below, or
must be pulled in from the diverted location. More information

Staging: panel: Add support for TI CLCD interface
On TI DA850/OMAP-L138 EVM, HD44780 (24x2) LCD panel is being
used[1], but it is interfaced through the SoC specific LCD
interface and not through parallel port. A parallel port
driver has been developed which interfaces to the panel driver
through the SoC specific LCD interface.
Basically, both the serial and parallel interfaces supported
by the panel driver do not suit the specific interface SoC is
supporting so, a new interface type has been introduced.
Ideally the panel driver should be de-coupled from parallel
and serial port related items but this patch is something
that can be merged in the meantime.
