Subject: gpio: mxs: fix duplicate level interrupts
Date: Fri, 21 Oct 2016 15:11:36 +0200 [thread overview]
Message-ID: <20161021131138.10467-1-s.hauer@pengutronix.de> (raw)
We observed that each level interrupt triggers two interrupts. This
is because the driver erroneously uses the IRQSTAT register to
acknowledge level interrupts which according to the reference manual
is not possible. Patch 2/2 fixes that, look for its commit message
for a detailed description what happens and how it is fixed.
