Hans de Goede c38a448a23 Input: alps - use single touch data when v3 mt data contains only one finger
For v3 protocol devices, use the more accurate single touch data when the
mt data contains only one finger. Note the mt data reporting a finger count
of 1 should never happen, but better safe then sorry.

This brings the v3 bitmap handling in line with what the v4 code does,
allowing to factor out the common bits into a helper function.

Hans de Goede cdf333efdc Input: alps - use standard contact tracking instead of DIY
When there are 2 fingers on the pad we don't know which one is which, so
use input_mt_assign_slots to make sure the right set of coordinates ends
up in the right slot.

Besides ensuring things end up in the right slot, this also results in a
nice cleanup, since sync_frame also handles non mt position and btn_touch
reporting.

Hans de Goede 02d04254a5 Input: alps - use struct input_mt_pos to track coordinates
This is a preparation patch for switching the DIY mt handling to using
input_mt_assign_slots && input_mt_sync_frame.

struct alps_fields is quite large, so while making changes to almost all uses
of it lets put it in our priv data instead of on the stack.

Having it in our priv data also allows using it directly for storing values
which need to be cached, rather then having separate x, y, z, fingers, etc.
copies in our priv data.

Hans de Goede 105affbfd5 Input: alps - process_bitmap: fix counting of high point bits
alps_process_bitmap was resetting the point bit-count as soon as it saw
2 0 bits in a row. This means that unless the high point actually is at
the end of the bitmap, it would always get its num_bits set to 0.

Instead reset num_bits to 0 on a 0->1 transition, so that with > 2 fingers
we only count the number of bits occupied by the highest finger.

Hans de Goede 40e8f53bff Input: alps - process_bitmap: don't invert the Y-axis on Rushmore
Rushmore models don't have the Y-axis data in the bitmap inverted. Since
we now have 2 different Y orientations, make the Y bitmap data processing
use a forward loop like the X bitmap data processing, unifying the 2,
and invert the data later, except on Rushmore.

So far no-one has noticed this because the synaptics driver only uses the
non mt coordinates (except on clickpads, and there are no alps clickpads
using process_bitmap).

Hans de Goede 20bea68bd1 Input: alps - improve 2-finger reporting on v3 models
V3 models only report mt bitmap data when there are 2 or more fingers on
the touchpad. So always generate 2 positions in alps_process_bitmap, and
for v3 models only fall back to st data when there was no mt data in a
mt packet (which should never happen).

This fixes 2 finger scrolling not working when using 2 fingers close to
each other.

Nick Dyer 8efaa5e5a9 Input: atmel_mxt_ts - recover from bootloader on probe
The MXT device may be in bootloader mode on probe, due to:
1) APP CRC failure, either:
  a) flash corruption
  b) bad power or other intermittent problem while checking CRC
2) If the device has been reset 10 or more times without accessing comms
3) Warm probe, device was in bootloader mode already

This code attempts to recover from 1(b) and 3.

There is an additional complexity: we have to try two possible bootloader
addresses because the mapping is not one-to-one and we don't know the exact
model yet.

Nick Dyer 50a77c658b Input: atmel_mxt_ts - download device config using firmware loader
The existing implementation which encodes the configuration as a binary
blob in platform data is unsatisfactory since it requires a kernel
recompile for the configuration to be changed, and it doesn't deal well
with firmware changes that move values around on the chip.

Atmel define an ASCII format for the configuration which can be exported
from their tools. This patch implements a parser for that format which
loads the configuration via the firmware loader and sends it to the MXT
chip.

Nick Dyer 7a53d60926 Input: atmel_mxt_ts - move input device init into separate function
It is useful to initialise the input device later:
- Screen parameters may not be not known yet, for instance if waiting for
  firmware loader to return.
- Device may be in bootloader mode on probe (but could still be recovered by
  firmware download).

In addition, later devices have a different touchscreen object (T100) which
requires handling differently.

This also reduces the complexity of the probe function.

Nick Dyer dd24dcf566 Input: atmel_mxt_ts - initialise IRQ before probing
The maXTouch chips use the CHG line to generate status events in bootloader
mode, and during configuration download, before there is enough information
to configure the input device. Therefore set up the interrupt handler
earlier.

However, this introduces states where parts of the interrupt processing
must not run. Use data->object_table as a way to tell whether the chip
information is valid, and data->input_dev as a way to tell whether it is
valid to generate input report.

Linus Torvalds 90d51d5606 NFS client fixes for Linux 3.16
Highlights include;
 - Stable fix for an NFSv3 posix ACL regression
 - Multiple fixes for regressions to the NFS generic read/write code
   - Fix page splitting bugs that come into play when a small rsize/wsize
     read/write needs to be sent again (due to error conditions or page
     redirty).
   - Fix nfs_wb_page_cancel, which is called by the "invalidatepage" method
 - Fix 2 compile warnings about unused variables.
 - Fix a performance issue affecting unstable writes.

Merge tag 'nfs-for-3.16-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client fixes from Trond Myklebust:
 "Apologies for the relative lateness of this pull request, however the
  commits fix some issues with the NFS read/write code updates in
  3.16-rc1 that can cause serious Oopsing when using small r/wsize.  The
  delay was mainly due to extra testing to make sure that the fixes
  behave correctly.

  Highlights include;
   - Stable fix for an NFSv3 posix ACL regression
   - Multiple fixes for regressions to the NFS generic read/write code:
     - Fix page splitting bugs that come into play when a small
       rsize/wsize read/write needs to be sent again (due to error

       method

Hans de Goede b4e05923f9 Input: add support for Wacom protocol 4 serial tablets
Recent version of xf86-input-wacom no longer support directly accessing
serial tablets. Instead xf86-input-wacom now expects all wacom tablets to
be driven by the kernel and to show up as evdev devices.

This has caused old serial Wacom tablets to stop working for people who still
have such tablets. Julian Squires has written a serio input driver to fix this:
https://github.com/tokenrove/wacom-serial-iv

This is a cleaned up version of this driver with improved Graphire support
(I own an old Graphire myself).
