Subject: [PATCH 4/4] input: TSC: ti_tscadc: Remove definition of End Of Interrupt register
Date: Wed, 22 Aug 2012 16:49:40 +0530 [thread overview]
Message-ID: <1345634380-29928-1-git-send-email-rachna@ti.com> (raw)
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.
