[PATCH v5 0/6] Touchscreen performance related fixes

From: Vignesh R
Date: Wed Dec 24 2014 - 02:06:04 EST


This series is rebase of v4 onto v3.19-rc1. It also fixes concerns
expressed on v4 wrt simultaneous use of IIO and TSC.

I have tested this patch series on am335x-evm and Beaglebone black
with lcd7-cape.

Note that, these patches do not work as expected on Beaglebone Black
with BB-View 4.3 Cape from Farnell due to a hardware issue in the cape.

Change log:

v5:
- Rebased onto v3.19-rc1
- minor changes in patch 2,3 and 5.

v3:
- Replace delta filtering logic in TSC driver with median filtering
as suggested by Richard.
- Addressed Lee Jones comments.

v2:
- Addressed comments by Hartmut Knaack
- patch 2 was split into two as per Lee Jones comment
