Subject: [PATCH 1/5] mfd: sunxi-gpadc-mfd: add TP_UP_PENDING irq
Date: Wed, 20 Jul 2016 10:29:07 +0200	[thread overview]
Message-ID: <1469003351-15263-2-git-send-email-quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <1469003351-15263-1-git-send-email-quentin.schulz@free-electrons.com>

This adds support for TP_UP_PENDING irq in Allwinner SoCs' GPADC's MFD.

This interrupt occurs when a touchscreen is attached and the thing (stylus,
finger) currently touching the touchscreen releases the touch.
