Cc: Dudley Du, bleung, jmmahler, devicetree, linux-input, linux-kernel
V0 patches mainly have following updates:
1) Add Gen6 trackpad device support;
2) Add report proximity data function support for Gen5 and Gen6 devices;
3) Fully support runtime suspend/resume power management;
4) Add of_match_table mechanism support.
This patch series is mainly amied to add new gen6 trackpad devices support,
and also new function to report proximity data/vent for Gen5 and Gen6 trackpad
devices.
Dudley Du (7):

The purpose of adding the proximity interface is: 1. User can apply the use of the proximity function as they want. Some productions may need the proximity function, but some may not. And for product, the requirements may be also different in the different usage time. so through this interface, user can apply their specific strategy to use the proximity function as required instead of the default behaver. The purpose of adding the interrupt interface is: 1. For temporary disable the trackpad device, user can disable the trackpad device to report data through the interrupt interface. And keep the trackpad device scanning when the data report is disabled, so when re-enable the report data of the device, the trackpad device can be re-enabled immediately without the disturb re-initialize processing. It may helpful in firmware debugging.
