2009-02-24i.MX31: add a simple gpio driverGuennadi Liakhovetski
This is a minimal driver, so far only managing output. It will be used by the mxc_spi.c driver. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
2008-12-19Add support for PCA953x I2C gpio devicesPeter Tyser
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. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
