Touchscreen is unfunctional after reset of the device during fw update.
Touch IC keep in flash mode and skip update due to incomplete query result.
Make touch fw update when driver detects flash mode during probing.
Initial parameters are also neccessary since querying to IC is unavailable.

The touchscreen controllers are field-swappable on both customer
devices and internal reference devices. It is possible to have
multiple Synaptics touch controllers where each controller would
support softkey in a different way. While some touch controllers
support 2-dimensional touch sensor, some others support capacitative
button(0D) sensing. In the former case, the touch sensor reports
native X-Y touch coordinates of the touch sensor in the soft key region.
This is implemented by RMI4 function F11 or F12 and software needs to
translate these coordinates to keycodes. In the latter case, the touch
sensor directly reports the key codes and hence there is no need for
software to do any translation. This is implemented by RMI4 function
F1A or F19.
The current architecture of Synaptics touchscreen driver does not have
support to disambiguate between more than two Synaptics touch controllers
that support 2-dimensional touch sensor for soft keys. To support
this functionality in driver, a device-tree property is defined that
describes the key codes for the soft-key area. The driver calculates
the total soft key area based on the display resolution and touch sensor
dimensions. Based on the total soft-key area and number of keys to be
supported, it calculates the area for each of the soft-keys. It exports
this information to userspace by populating a sysfs file. User-space
programs can then translate the touch coordinates received to key codes.

The touchscreen controllers are field-swappable on both customer
devices and internal reference devices. Current touch driver
architecture for Synaptics does not support dynamic detection
of two or more Synaptics touchscreens having same slave address. The
patch provides a solution for the scenario in which it is required
to swap two Synaptics touchscreens without changing DT. Support of
this is added in driver as follows:
1. During driver probe, touch controller is identified by reading
the Package Id from controller. Package ID in F01_RMI_Query register
comprises of a 16-bit Package ID and a 16-bit Package ID Revision
of which both are unique for a touch controller part. If Package ID
is present,then a RMI read operation in UI Mode at seventeenth
register from F01 Query base returns it. First two bytes of this
Package ID base are used to select the correct Synaptics touch
controller from device tree.
2. Add a new property synaptics,detect-device in DT files which
will allow software to enable this logic to detect correct
touchscreen slave.
3. All such devices are placed as child nodes of Synaptics
Touchpanel node. These child nodes are parsed only if the property
synaptics,detect-device is defined in DT file.

This change removes source files from the kernel tree that
were not being used during make. The list of used files
was generated using an annotated make log and was then
compared with new files added since the public release of
kernel version 3.10.00. New files which were added but
not used have been removed from the tree.
A diff was also run to determine the list of files that had
been modified since the release of kernel version 3.10.00.
These files were then scrubbed based on the current kernel
configuration, removing invalid and unused conditionals.
Some files which support planned functionality or are
useful in debugging have been excluded from this reap.
