From mboxrd@z Thu Jan 1 00:00:00 1970 From: quentin.schulz@free-electrons.com (Quentin Schulz) Date: Wed, 20 Jul 2016 10:29:07 +0200 Subject: [PATCH 1/5] mfd: sunxi-gpadc-mfd: add TP_UP_PENDING irq In-Reply-To: <1469003351-15263-1-git-send-email-quentin.schulz@free-electrons.com> References: <1469003351-15263-1-git-send-email-quentin.schulz@free-electrons.com> Message-ID: <1469003351-15263-2-git-send-email-quentin.schulz@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
