Subject: [PATCH 1/2] gpio: axp209: use correct register for GPIO input status
Date: Wed, 23 Nov 2016 14:27:48 +0100	[thread overview]
Message-ID: <20161123132749.11666-2-quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <20161123132749.11666-1-quentin.schulz@free-electrons.com>

The GPIO input status was read from control register
(AXP20X_GPIO[210]_CTRL) instead of status register (AXP20X_GPIO20_SS).
