Hi,
I noticed that my board-overo.c file (for Gumsix Overo Fire TI OMAP
3530 device) is missing the ads7846_vaux_control.
Is this a recent change that will impact the responsiveness of the
touchscreen controller?
Best regards,
Elvis

Hi,
I just noticed that after incorporating the SR reflex and the
recent patches from 187 onwards (using git format patch master on
the pm branch),
my ADS7846 touchscreen controller's response has become modified.
Any possible links or is there some dependency between the SR reflex
patches and the pm patches for the ADS7846 touchscreen controller?
Best regards,
Elvis
