In linux kernel since version 2.6.25 (release Date: 2008-04-16)
Say yes here to provide access to several register-oriented
SMBus I/O expanders, made mostly by NXP or TI. Compatible
models include:
4 bits: pca9536, pca9537
8 bits: max7310, pca9534, pca9538, pca9554, pca9557
16 bits: pca9535, pca9539, pca9555
This driver can also be built as a module. If so, the module
will be called pca953x.
