Move all the semi-mt specific handling shared between the v3 and v4 handling code to a common helper function. Signed-off-by:

Hans de Goede authored
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. Signed-off-by:

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. Signed-off-by:

Hans de Goede authored
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. Signed-off-by:

This fixes 2 fingers at the same height or width on the touchpad getting reported at different y / x coordinates. Note num_bits is always at least 1. Signed-off-by:

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. Signed-off-by:

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). Signed-off-by:

Hans de Goede authored
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. Signed-off-by:

This adds a driver for the touchscreen connected to the Atmel microcontroller on the iPAQ h3xxx series. Based on a driver from handhelds.org 2.6.21 kernel, written by Alessandro GARDICH, with the bulk of the code for the new input architecture rewritten by Dmitry Atamonow, and the final polish by Linus Walleij.

maXTouch chips allow the reading of multiple messages in a single I2C transaction, which reduces bus overhead and improves performance/latency. The number of messages available to be read is given by the value in the T44 object which is located directly before the T5 object. Signed-off-by:

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. Signed-off-by:

By validating the checksum, we can identify if the configuration is corrupt. In addition, this patch writes the configuration in a short series of block writes rather than as many individual values. Signed-off-by:
-
Nick Dyer authored
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. Signed-off-by:

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. Signed-off-by:

Nick Dyer authored
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. Signed-off-by:
