| Subject | [PATCH v2] gpio/pca953x: Add TI TCA9539 support |
| Message-ID | <qe0NA-4fJ-15@gated-at.bofh.it> |
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.
Signed-off-by: Thierry Reding <treding@nvidia.com>
