Subject: [PATCH] gpio/pca953x: Add TI TCA9539 support
Date: Wed, 9 Sep 2015 17:23:22 +0200 [thread overview]
Message-ID: <1441812202-1915-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
The TCA9539 is almost identical to the PCA9555 and software-compatible
with this driver. It exposes 16 general purpose I/O pins in two 8-bit
configurations.
