* Input: elan_i2c - reduce the resume time for controller in Whiteboxjingle.wu2021-09-062-1/+3
| | | | | | | | | | | Similar to controllers found Voxel, Delbin, Magpie and Bobba, the one found in Whitebox does not need to be reset after issuing power-on command, and skipping reset saves resume time.

| * | Input: elantech - Prepare a complete software node for the deviceHeikki Krogerus2021-04-101-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creating a software node and supplying that for the device instead of only the device properties in it. A software node was always created in any case to hold the additional device properties, so this change does not have any real effect. This change makes it possible to remove support for the problematic "dangling" device properties from i2c subsystem, i.e. the "properties" member from struct i2c_board_info. The problems caused by them are not related to this driver.

| * | | Input: elan_i2c - add support for high resolution reportsJingle Wu2020-07-214-59/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer controllers (identified as "pattern" version 2) send higher resolution reports, with 16-bit X and Y coordinates (previous generations used 12-bit values). These new high resolution reports use report ID of 0x60. SMbus controllers use the same buffer size for both the new and old reports, and because of that high resolution reports no longer carry area of contact data with SMbus.

| | | | | | | | | | | | | | | | | | | | | | | | We do not need to constantly re-query pattern ID, we can instead query it once and then pass to methods that need it. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds firmware size and page sizes for ic types 0x11, 0x13 and 0x14. IC 0x14 uses 512-byte firmware page size. Signed-off-by: Jingle Wu <jingle.wu@emc.com.tw>. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer ICs with IC type value starting with 0x0D and newer bootloader code use 128-byte firmware pages. Their bootloader also needs to be switched to proper mode before executing firmware update. Signed-off-by: Jingle Wu <jingle.wu@emc.com.tw> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Older controllers in bootloader mode need a different command to retrieve the IAP version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend fetching and parsing parameters of the controllers to devices with "patterns" above 1 (which currently should be handled in the same fashion as devices with pattern 1).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On older controllers IC type is reported in the 2nd byte of ETP_I2C_OSM_VERSION_CMD, however if controller's firmware is not flashed correctly it may return incorrect data. Fortunately there is also ETP_I2C_IAP_VERSION_P0_CMD command that can be used when controller in either normal or IAP mode, and which is guaranteed to return accurate data, so let's use it.
