This patch adds gpio-pcal9535a.c and gpio-pcal9535a.h files, which support access to I2C-based PCAL9535A GPIO controller configuration register through a function interface. The PCAL9535A is a low-voltage 16-bit GPIO expander with interrupt and reset for I2C-bus/SMBus applications. It contains the PCA9535 register set of four pairs of 8-bit Configuration, Input, Output, and Polarity Inversion registers, and additionally, the PCAL9535A has Agile I/O, which are additional features specifically designed to enhance the I/O. More about PCAL9535A can be found in its datasheet[1]. This driver is needed in order to configure Galileo pinmux. [1] - http://www.nxp.com/documents/data_sheet/PCAL9535A.pdf
