fe28f5de11 [media] ati_remote: Put timeouts at the accel array
Instead of having the timeouts hardcoded, and getting only the
accel value from the array, put everything in the same place.

That simplifies the logic.

As a side effect, it also cleans several smatch errors:
	include/linux/jiffies.h:359:41: error: strange non-value function or array
	include/linux/jiffies.h:361:42: error: strange non-value function or array
(one per time_after/time_before line)

Rather than having special code cases for diagonal mouse
movements, extend the general purpose code used for the
cardinal directions to handle arbitrary (x,y) deltas.

The deltas themselves are stored in translation table's "code"
field; this is also progress toward the goal of eliminating
the "value" element entirely.

f95589cc41 [media] ati_remote: Delete superfluous input_sync()
It's not necessary, and since both events happen "at the same time"
in response to a single input event, the input device framework prefers
not to have it there.

(It's not a big deal one way or the other, but deleting cruft

20d7e3ca1b [media] ati_remote: Check the checksum
An input report is 4 bytes long, but there are only 12 bits
of actual payload.  The 4 bytes are:
data[0] = 0x14
data[1] = data[2] + data[3] + 0xd5 (a checksum byte)
data[2] = the raw scancode (plus toggle bit in msbit)
data[3] = channel << 4 (the low 4 bits must be zero)

Ignore reports with a bad checksum.

c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

120703f9eb [media] rc-core: document the protocol type
Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

70ef69915b [media] rc: Make probe cleanup goto labels more verbose
Before, labels were simply numbered. Now, the labels are named after the
cleanup action they'll perform (first), based on how the winbond-cir
driver does it. This makes the code a bit more clear and makes changes
in the ordering of labels easier to review.
This change is applied only to the rc drivers that do significant
cleanup in their probe functions: ati-remote, ene-ir, fintek-cir,
gpio-ir-recv, ite-cir, nuvoton-cir.
This commit should not change any code, it just renames goto labels.

c003ab1bed [media] rc-core: add separate defines for protocol bitmaps and numbers
The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.

Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.

Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.

Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).

The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).

This patch separate the different usages in preparation for
upcoming patches.

Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.

The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

5085c99eeb [media] ati_remote: add keymap for Medion X10 OR2x remotes
Add another Medion X10 remote keymap. This is for the Medion OR2x
remotes with the Windows MCE button.

The receiver shipped with this remote has the same USB ID as the other
Medion receivers, but the name is different and is therefore used to
detect this variant.

9d454d48eb [media] ati_remote: add support for Medion X10 Digitainer remote
Add support for another Medion X10 remote. This was apparently
originally used with the Medion Digitainer box, but is now sold
separately without any Digitainer labeling.

A peculiarity of this remote is a scrollwheel in place of up/down
buttons. Each direction is mapped to 8 different scancodes, each
corresponding to 1..8 notches, allowing multiple notches to the same
direction to be transmitted in a single scancode. The driver transforms
the multi-notch scancodes to multiple events of the single-notch
scancode.
(0x70..0x77 = 1..8 notches down, 0x78..0x7f = 1..8 notches up)

Since the scrollwheel scancodes are the same that are used for mouse on
some other X10 (ati_remote) remotes, the driver will now check whether
the active keymap has a keycode defined for the single-notch scancode
when a mouse/scrollwheel scancode (0x70..0x7f) is received. If set,
scrollwheel is assumed, otherwise mouse is assumed.

This remote ships with a different receiver than the already supported
Medion X10 remote, but they share the same USB ID. The only difference
in the USB descriptors is that the Digitainer receiver has the Remote
Wakeup bit set in bmAttributes of the Configuration Descriptor.
Therefore that is used to select the default keymap.

Thanks to Stephan Raue from OpenELEC (www.openelec.tv) for providing me
both a Medion X10 Digitainer remote+receiver and an already supported
Medion X10 remote+receiver. Thanks to Martin Beyss for providing some
useful information about the remote (including the "Digitainer" name).
This patch has been tested by both of them and myself.

5eefb4f09b [media] ati_remote: switch to single-byte scancodes
The ati_remote driver currently uses 2-byte scancodes. However, one of
those bytes is actually a checksum and therefore shouldn't be considered
as part of the scancode.

Fix the driver to only use the actual data byte as a scancode and to
check the checksum itself. Update the bundled keymaps accordingly.

Since ati_remote was only migrated to the rc subsystem for 3.2, the
previous scancodes weren't emitted on any stable kernel.
