2014-07-28Input: atmel_mxt_ts - use deep sleep mode when stoppedNick Dyer
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.

2014-07-23Input: atmel_mxt_ts - implement T44 message handlingNick Dyer
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.

The T5 object may have various sizes depending on the objects used on the particular maXTouch chip and firmware version, therefore it can't be hardcoded in the driver.

2014-07-23Input: atmel_mxt_ts - recover from bootloader on probeNick Dyer
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.

2014-07-23Input: atmel_mxt_ts - calculate and check CRC in config fileNick Dyer
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.

2014-07-23Input: atmel_mxt_ts - download device config using firmware loaderNick Dyer
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.

2014-07-23Input: atmel_mxt_ts - move input device init into separate functionNick Dyer
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.

2014-07-23Input: atmel_mxt_ts - initialise IRQ before probingNick Dyer
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.
