[PATCH 4/4] input: TSC: ti_tscadc: Remove definition of End Of Interrupt register

[Patil, Rachna]

The touchscreen IP uses level sensitive interrupts rather
than edge sensitive interrupts and therefore the is no need
to use the EOI register to have the module re-strobe the
interrupt line if there pending interrupts exist.
