Subject: [PATCH RESEND 4/8] input: TSC: ti_tscadc: Remove definition of End Of Interrupt register
Date: Tue, 16 Oct 2012 12:55:41 +0530	[thread overview]
Message-ID: <1350372345-27108-5-git-send-email-rachna@ti.com> (raw)
In-Reply-To: <1350372345-27108-1-git-send-email-rachna@ti.com>

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.
