2016-08-25Input: elants_i2c - get product id on recovery mode for FW updateJohnny Chuang1-11/+20
We use hw version to construct name of file holding touchscreen firmware, so let's try reading it even if touchscreen initialization fails (the firmware supports reading product/hardware id even when device is in recovery/boot mode).

2016-08-25Input: wm97xx - remove deprecated create_singletheread_workqueueBhaktipriya Shridhar1-1/+1
alloc_ordered_workqueue() replaces deprecated create_singlethread_workqueue(). It queues work items via &wm->ts_reader and &wm->pen_event_work which map to wm97xx_pen_irq_worker (handles a pen down interrupt) and wm97xx_ts_reader (the touchscreen sample reader) respectively. Hence, an ordered dedicated workqueue has been used.

2016-08-25Input: mc13783_ts - remove deprecated create_singletheread_workqueueBhaktipriya Shridhar1-17/+7
The workqueue "workqueue" has a single workitem(&priv->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Workitem is sync cancelled in mc13783_ts_remove() to ensure that there are no workitems pending when the driver is disconnected.

The new(ish) ft6236 simply re-implements the M09 protocol of the (much) older edt-ft5x06.c driver. This commit removes this duplicate driver and adds the i2c ids and dt compatible string to the edt-ft5x06.c driver to keep compatibility.
