A failure to locate the external subdev for a non memory-to-memory
pipeline is a fatal error, don't ignore it.

Memory-to-memory pipelines have no external subdev, we shouldn't try to
locate one and validate its configuration. The driver currently works by
chance due to another bug that results in failure to locate the external
subdev being ignored.
This gets rid of the "omap3isp omap3isp: can't find source, failing now"
error message in the kernel log when operating on a memory-to-memory
pipeline.

Drop the vid_limit module option: there is really no need to limit this.
No other driver does that. If you try to allocate more buffers then vb2
will automatically reduce the number of buffers anyway.
Also add sanity checks if the size in the fmt argument is going to be
used and drop the code that checks against *nbuffers == 0: this can
never happen (the vb2 framework ensures that) and the code was wrong
anyway since *nbuffers should have been set to the minimum number of
required buffers which is 1 for this driver.
Since vivi is often used as a template driver it is good to have this
driver be as compliant as possible. This broken code was for example
copied to the s2255 driver (which is being fixed as well).

The sequence counting was not reset to 0 between each streaming run,
and it was increased only every other frame. This is incorrect behavior:
the confusion is with FIELD_ALTERNATE systems where each field is transmitted
separately and only when both fields have been received is the frame
sequence number increased.

Add support for 32-bit ioctls with v4l-subdev device nodes.
Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.
We keep forgetting to add new ioctls, so this is a more robust solution.
In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.
So for the raw NEC data:
(LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)
We now generate the scancodes:
(MSB) 0x0000AACC (LSB) (normal NEC)
(MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
(MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)
Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.
The TiVo keymap is updated accordingly.

Add and document a generic sysfs based scancode filtering interface for
making use of IR data matching hardware to filter out uninteresting
scancodes. Two filters exist, one for normal operation and one for
filtering scancodes which are permitted to wake the system from suspend.
The following files are added to /sys/class/rc/rc?/:
- filter: normal scancode filter value
- filter_mask: normal scancode filter mask
- wakeup_filter: wakeup scancode filter value
- wakeup_filter_mask: wakeup scancode filter mask
A new s_filter() driver callback is added which must arrange for the
specified filter to be applied at the right time. Drivers can convert
the scancode filter into a raw IR data filter, which can be applied
immediately or later (for wake up filters).

There are reports[1] that on some motherboards loading the nuvoton-cir
disables PS/2 keyboard input. This is caused by an erroneous write of
CIR_INTR_MOUSE_IRQ_BIT to ACPI control register.
According to datasheet the write enables mouse power management event
interrupts which will probably have ill effects if the motherboard has
only one PS/2 port with keyboard in it.
The cir hardware does not need mouse interrupts to function and should
not touch them. This patch removes the illegal writes and registry
definitions.

But the proper error code for unknown errors is -EIO.

are according to Mauro Carvalho Chehab's tests related to i2c clock
stretching and return -EIO for the rest.

Add a raw decoder for the Sharp protocol. It uses a pulse distance
modulation with a pulse of 320us and a bit period of 2ms for a logical 1
and 1ms for a logical 0. The first part of the message consists of a
5-bit address, an 8-bit command, and two other bits, followed by a 40ms
gap before the echo message which is an inverted version of the main

Since v3.12, specifically 153a60bb0fac ([media] rc: add feedback led
trigger for rc keypresses), an LED trigger is activated on IR keydown
whether or not a keypress is generated (i.e. even if there's no matching
keycode). However the repeat and keyup logic isn't used unless there is
a keypress, which results in non-keypress keydown events turning on the
LED and not turning it off again.
On the assumption that the intent was for the LED only to light up on
valid key presses (you probably don't want it lighting up for the wrong
remote control for example), move the led_trigger_event() call inside
the keycode check.

This applies to HDMI-map register 0x69.
So far we have been using HPA manual mode.
This way we had control of HPA which could be
set after EDID had been programmed.
Using a Mac Mini with mini-displayport to DVI-D converter as source
caused the adv7842 to lock up and fail to detect any further signals.
After experimenting with different configurations it was found that
using the HPA auto mode and in addition letting RX-termination
be controlled by HPA prevented this error from occuring.
I was not able to re-create this problem on the adv7604.
