- Say yes here to support the PCA9534 (8-bit), PCA9535 (16-bit),
- PCA9536 (4-bit), PCA9537 (4-bit), PCA9538 (8-bit), and PCA9539
- (16-bit) I/O ports. These parts are made by NXP and TI.
+ Say yes here to provide access to several register-oriented
+ SMBus I/O expanders, made mostly by NXP or TI. Compatible

+
+ 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.

Say yes here to provide access to most "quasi-bidirectional" I2C
some of them. Compatible models include:
