OMAPDSS: hide dss_select_dispc_clk_source()
dss.c currently exposes functions to configure the dispc source clock
and lcd source clock. There are configured separately from the output
drivers.
However, there is no safe way for the output drivers to handle dispc
clock, as it's shared between the outputs. Thus, if, say, the DSI driver
sets up DSI PLL and configures both the dispc and lcd clock sources to
that DSI PLL, the resulting dispc clock could be too low for, say, HDMI.
Thus the output drivers should really only be concerned about the lcd
clock, which is what the output drivers actually use. There's lot to do
to clean up the dss clock handling, but this patch takes one step
forward and removes the use of dss_select_dispc_clk_source() from the
output drivers.
After this patch, the output drivers only configure the lcd source
clock. On omap4+ the dispc src clock is never changed from the default
PRCM source. On omap3, where the dispc and lcd clocks are actually the
same, setting the lcd clock source sets the dispc clock source.

OMAPDSS: DSI: skip odd dividers when pck >= 100MHz
The DSI PLL and HSDivider can be used to generate the pixel clock for
LCD overlay manager, which then goes to DPI output. On the DPI output
pin the voltage of the signal is shifted from the OMAP's internal
minimal voltage to 1.8V range. The shifting is not instant, and the
higher the clock frequency, the less time there is to shift the signal
to nominal voltage.
If the HSDivider's divider is greater than one and odd, the resulting
pixel clock does not have 50% duty cycle. For example, with a divider of
3, the duty cycle is 33%.
When combining high frequency (in the area of 140MHz+) and non-50% duty
cycle, it has been observed the the shifter does not have enough time to
shift the voltage enough, and this leads to bad signal which is rejected
by monitors.
As a workaround this patch makes the divider calculation skip all odd
dividers when the required pixel clock is over 100MHz. The limit of
100MHz is a guesstimate.

Enabling the video output for these operations is not a big problem in

OMAPDSS: DSI: fix dsi_get_dsidev_from_id()
If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.
This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.
Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

This has the undesirable effect of breaking the EFI boot stub because
the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is

It should also be noted that because $(USERINCLUDE) isn't exported by

(1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked
this with Paul Mackerras before I created the patch and he suggested some
extra bits to unexport.
(2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace
applicable, and remove from the UAPI that part of linux/fs.h that was the
reason for linux/blk_types.h being exported in the first place. I
discussed this with Jens Axboe before creating the patch.
(3) The big patch of the series to disintegrate include/linux/*.h as a unit.
This could be split up, though there would be collisions in moving stuff
between the two Kbuild files when the parts are merged as that file is
sorted alphabetically rather than being grouped by subsystem.
Of this set of headers, 17 files have changed in the UAPI exported region
since the 4th and only 8 since the 9th so there isn't much change in this
area - as one might expect.
It should be pretty obvious and straightforward if it does come to fixing
up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
to the same file in the include/uapi/linux/ directory.
If a new file appears then things get a bit more complicated as the
"headers +=" line has to move to include/uapi/linux/Kbuild. Only one new
file has appeared since the 9th and I judge this type of event relatively
unlikely.

ARM: config: sort select statements alphanumerically
As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
