- Say yes here to support the PCA9539 16-bit I/O port. 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
+ 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 pca9539.
+ will be called pca953x.
