Subject: gpio: pca953x (i2c) handles max7310 too
From: David Brownell <david-b@xxxxxxxxxxx>
The pca953x driver can handle another 8-bit I/O expander, the max7310.
This patch adds that chip to the list of supported IDs in that driver, and
expands the Kconfig helptext accordingly.

+ 16 bits: pca9535, pca9539, pca9555
This driver can also be built as a module. If so, the module
will be called pca953x.
