#8 [Patch] Support for ELO touchscreen using General Touch ST6001S controller.

[Gareth Randall]

Hi. This is a patch in order to ask the Linux kernel to support a variant of the ELO touchscreen that requires a different initialisation string in order to function.

The patch allows inputattach to select a different ELO id parameter (4).

The kernel patch for the Linux change is not yet merged but the code for it can be seen in this post to the relevant mailing list:
https://lore.kernel.org/linux-input/83a934eb-e1ee-fd79-33ee-76413be2e6ea@virgin.net/T/#m6caed1d2c1bb262440cd7950207c7fa67b17edb1

I have posted this as a feature request as the "Patch" option does not appear to be enabled for Tickets. I hope this is okay.

The patch is both pasted below for your reference and also attached.

Thank you.
