2018-07-27Input: wdt87xx_i2c - replace mdelay() with msleep() in wdt87xx_resume()Jia-Ju Bai1-1/+1
wdt87xx_resume() is never called in atomic context. It calls mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2018-01-16Input: remove unneeded MODULE_VERSION() usage in touchscreen driversGreg Kroah-Hartman1-2/+0
MODULE_VERSION is useless for in-kernel drivers, so just remove all usage of it in the touchscreen drivers. Along with this, some DRV_VERSION macros were removed as they are also pointless.

2017-09-29Input: wdt87xx_i2c - use managed devm_device_add_groupAndi Shyti1-9/+1
Commit 57b8ff070f98 ("driver core: add devm_device_add_group() and friends") has added the managed version for creating sysfs group files. Use devm_device_add_group instead of sysfs_create_group and remove the relative sysfs_remove_group.

2016-09-05Input: wdt87xx_i2c - fix the flash erase issueHungNien Chen1-2/+3
The spec says that flash erase time is 30ms typical/200ms max, so let's replace current 50ms wait with 200ms to avoid potential failures. Signed-off-by: HungNien Chen <hn.chen@weidahitech.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2015-07-11Input: wdt87xx_i2c - change the sleep time to 2500ms after the sw resetHungNien Chen1-1/+2
The original wait time was 200ms which was enough for the firmware to finish loading and boot. After that the firmware will perform initialization and touch calibration, which will take about 1.1 second. The touch calibration will change controller frequency to scan at the most optimal frequency and during calibration/frequency switching process we may run into i2c data errors. To avoid them we extend the sleep to 2500ms after issuing the sw reset. Signed-off-by: HungNien Chen <hn.chen@weidahitech.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
