We can annotate the suspend/resume functions with '__maybe_unused' and get rid of the ifdef, which makes the code smaller and simpler. Signed-off-by:

When a kernel has CONFIG_PM=y and CONFIG_PM_SLEEP=n the following warnings are seen: drivers/input/touchscreen/mcs5000_ts.c:252:12: warning: 'mcs5000_ts_suspend' defined but not used [-Wunused-function] static int mcs5000_ts_suspend(struct device *dev) ^ drivers/input/touchscreen/mcs5000_ts.c:262:12: warning: 'mcs5000_ts_resume' defined but not used [-Wunused-function] static int mcs5000_ts_resume(struct device *dev) Protect the suspend/resume functions with CONFIG_PM_SLEEP in order to fix these build warnings.

By writing zero to both the active and idle cycle times the maXTouch device is put into a deep sleep mode when it consumes minimal power. It is unnecessary to change the configuration of any other objects (for example to disable T9 touchscreen). It is counterproductive to reset the chip on resume, it will result in a long delay. However it is necessary to issue a calibrate command after the chip has spent any time in deep sleep. This patch also deals with the situation where the power configuration is zero on probe, which would mean that the device never wakes up to execute commands. Signed-off-by:

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:

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:
