[PATCH] gpio: Enable pcf857x GPIO expander for Device Tree

2013-06-06 Thread Archit Taneja
Add code to parse the GPIO expander Device Tree node and extract platform data out of it, and populate the struct 'pcf857x_platform_data' maintained by the driver. This enables devices to reference the gpio expander from Device Tree. Add DT binding info in Documentation. CC: Grant Likely Signed-
