Hi,
One idea as below
struct spi_dss_device {
struct omap_dss_device dss_dev;
struct spi_dss_dev_priv * spi_data;
} spi_dss_dev;
spi_dss_probe.c
spi_probe(spi_device * spi)
{
spi_dss_dev. spi_data = spi;
omap_dss_register_device((spi_ device *) &spi_dss_dev);
}
spi_dss_drv.c
spi_dss_drv_probe(omap_dss_device * dev)
{
my_spi_dss_dev = container_of(dev, struct spi_dss_device, dss_dev);
spi_data = my_spi_dss_dev;
}
