[PATCH v3 2/2] gpio: pca953x: Add support for the PCAL9535

[Jan Kiszka <jan.kiszka@xxxxxxxxxxx>]

From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

The PCAL9535 is compatible to the PCA9535. Additionally, it comes with
interrupt support and input latching. Other features are not supported
by the GPIO subsystem.
