@@ -746,6 +746,10 @@ The following options need to be configured:
CONFIG_PCA953X - use NXP's PCA953X series I2C GPIO
CONFIG_PCA953X_INFO - enable pca953x info command
+ The CONFIG_SYS_I2C_PCA953X_WIDTH option specifies a list of
+ chip-ngpio pairs that tell the PCA953X driver the number of
+ pins supported by a particular chip.

Note that if the GPIO device uses I2C, then the I2C interface
must also be configured. See I2C Support, below.
