A little bit of cleanup work for 'wacom_update_name' to make it easier on
the eyes. Creates a temporary 'name' variable on which we'll perform our
edits. Once the name is in its final form, it will be copied (with
appropriate suffix) to 'wacom_wac->name' and 'wacom_wac->pad_name'.

The USB devices that this driver has historically supported segregate the
pen and touch portions of the tablet. Oftentimes the segregation would be
done at the interface level, though on occasion (e.g. Cintiq 24HDT) the
tablet would combine two totally independent USB devices behind an internal
USB hub. Because pen and touch never shared the same interface, it made
sense for the 'device_type' to store a single value: "pen" or "touch".
Recently, however, some I2C devices have been created which combine the
two. A first step to accomodating this is to expand 'device_type' so that
it can represent two (or potentially more) types simultaneously. To do
this, we treat it as a bitfield and set/check individual bits rather
than using the '=' and '==' operators.
This should not result in any functional change since no supported devices
(that I'm aware of, at least) have HID descriptors that indicate both
pen and touch reports on a single interface.

As you mentioned, we are safe right now because there is no device that
shares both pen and touch on the same HID interface (expect the one you
are making the patch series for).
I am just wondering if this will not bite us back when we will have to
use a features->x_pen_max and features_x_touch_max for the same
interface.
No need to change it now (I guess we are fine with HID generic devices
right now), but this is something we might want to have in our heads in
the future.
Cheers,
Benjamin

See my comments on patch 5. I'm in complete agreement -- I don't think
it's an issue (thanks to HID_GENERIC), but the design is a little creaky
given the kinds of devices out there. I'd like to see the driver be more
tool-centric and not have to repeat myself three times in every function
to e.g. set the name of the pen, touch, and pad device.

Historically, both the touch and pad tools would have shared the
'BTN_TOOL_FINGER' type. Any time you needed to distinguish the two, you
had to use some other bit of knowledge (e.g. that the pad was on the same
interface as the pen, and thus 'touch_max' would be zero).
To make these checks more readable, we introduce WACOM_DEVICETYPE_PAD.
Although we still have to rely on other bits of knowledge to set this
bit on the right interface (since it cannot be detected from the HID
descriptor), it can be done just once inside 'wacom_setup_device_quirks'.
This patch introduces no functional changes.

This splits the 'wacom_setup_pentouch_input_capabilites' function into
pieces dedicated to doing setup for just the pen interface and just
the touch interface. This makes it easier to focus on the relevant
piece when making changes.
This patch introduces no functional changes.

Instead of having a single 'input_dev' device that will take either pen
or touch data depending on the type of the device, create seperate devices
devices for each. By splitting things like this, we can support devices
(e.g. the I2C "AES" sensors in some newer tablet PCs) that send both pen
and touch reports from a single endpoint.

Besides the Wacom PAD problem already mentioned in the 0/5 thread (I
will test it tomorrow and come with a following patch if need), I have 2

I know you are not introducing anything new here, but that means that
now, we reserve 3 input devices, while we might not even use one.
I just wonder if we should not start having a smarter input allocation
in wacom.ko where we would create the inputs only if they are needed.
IIRC, I came to use this extra pad input node to have all the bits in
place while parsing the report descriptor, but maybe we could be
smarter.

I've been considering this as well. I was thinking about creating some
kind of structure to allow us to better separate the individual tools
(e.g. a kind of tool-specific "wacom_wac" with name, input device, and
features [addressing your concerns in patch 2]) but haven't come up with
a good design yet. Its on my list of back-burner tasks, though we might
be able to do something about the excess allocations themselves without
quite as much work.

Thanks. There's definitely a chance for subtle interactions, and while I
hope I've covered all my bases I'm glad to have the extra eyes and brain
cells :D

This all seems sensible. I gave a quick look yesterday and could not
found any obvious problem, but I'd like to review it more thoroughly
before giving my rev-by (and do a little bit of testing too).
I don't believe there will be any problems for the series, besides the
Bamboo PAD. Have you tested on this?
Cheers,
Benjamin

I don't have a Bamboo PAD to test with, but carefully looking at each
interface's HID descriptor makes me think you may be right. The debug
interface in particular uses a WACOM_VENDORDEFINED_PEN application
collection and will be marked as WACOM_DEVICETYPE_PEN instead of
WACOM_DEVICETYPE_TOUCH.
The smallest fix that should do the trick would be to just swap the
device_type in 'wacom_setup_device_quirks'. Alternatively, we could only
allow the debug interface to be probed, set the touch device type flag
(in addition to the automatically-set pen flag), and extend the IRQ
function to explicitly handle pen events. The alternative is a bit more
work (and we'd need somebody with a device to test it...) but I think
might make the codepath for the Bamboo PAD a bit easier to follow.

Just a quick update (and I'll review the series, I promise!).
The Bamboo PAD still works with this series. The only difference from
the current code is that now, we have an extra "pen" input node (unused)
attached to the touch interface (it was maybe what you were saying, but
it was not entirely clear for me, sorry :-P ).

Yeah. That is pretty much what we currently have for handling the PAD.
When the parsing has been made, I just revert the tool.

It might be easier to follow, but that would mean to implement a n-th
protocol, while the descriptor already gives us the protocol. So not

So, besides the typo in 5/5, the series is:

I'll send a follow up patch to fix the Bamboo PAD extra interface once
this will land in Jiri's tree.

Just stumbled across a bug with wireless operation (missing pad device).
Hopefully Jiri hasn't merged anything yet :)

Indeed, this was still in my 'hid-todo' queue. Given the comments so far,
I am removing this patchset from it, and waiting for v2 refresh.
