In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".

That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.

This patch renames the "output" field to "src", which much better tells
what the field points to.

Regulator handling for DPI and SDI is currently handled in the core.c,

The DPI and SDI platform devices are currently created with the ID of
-1. The ID doesn't currently affect anything.

However, we have added regulator supply entries for "omapdss_dpi.0" and
"omapdss_sdi.0" to the board files, although these supply entries are
not yet used. As the ID used for the devices is -1, these regulator
supply entries will not work.

To fix the issue, assign ID of 0 to the devices. In the future there may
be more than one DPI or SDI output, so it makes sense to have a proper
ID for them.

OMAPDSS's RFBI encoder driver has not been working for some time. The
Nokia N800 is the only board in the mainline that uses RFBI, but it has
never been fully functional.

The RFBI driver needs to be updated to the new panel model, but as
the driver is rather unmaintained and there's no way to test the
changes, let's mark the driver as broken.

Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs
for the panels. This means that both panel devices cannot be probed at
the same time.

DT will handle this correctly, i.e. the DT data will contain the panel
device only for the add-on board that is attached. However, for the
board file we need a hackish solution: We parse the kernel boot command
line, and see whether lcd43 or lcd35 is set as a default display, and
add the given one. Or, if neither is given, default to lcd43.

4430SDP board has an option for a PicoDLP mini-projector. PicoDLP cannot
be used at the same time as the second LCD, and there are GPIOs that
need to be set/unset when changing the used display.

Managing that kind of board specific setup is not simple without board
file callbacks. As only some 4430SDP boards actually have the PicoDLP
installed, and 4430SDP boards are not that common in the first place,
let's remove PicoDLP data from the board file.

Commit 0713ed0c added
jbd2_journal_file_inode() call into ext4_block_zero_page_range().
However that function gets called from truncate path and thus inode
needn't have jinode attached - that happens in ext4_file_open() but
the file needn't be ever open since mount. Calling
jbd2_journal_file_inode() without jinode attached results in the oops.

We fix the problem by attaching jinode to inode also in ext4_truncate()
and ext4_punch_hole() when we are going to zero out partial blocks.
