    Add support for PCA953x I2C gpio devices · e92739d3
    Peter Tyser authored
    Initial support for NXP's 4 and 8 bit I2C gpio expanders
    (eg pca9537, pca9557, etc). The CONFIG_PCA953X define
    enables support for the devices while the CONFIG_CMD_PCA953X
    define enables the pca953x command. The CONFIG_CMD_PCA953X_INFO
    define enables an 'info' sub-command which provides summary
    information for the given pca953x device.
