> This patch adds the chip_select as parameter to
> omap_ads7846_init.
> All existing omap2-boards use chip select 0 on
> different spi busses. I work on bringing a board
> mainline where the ads7846 is connected to
> chip select 1. This patch prepares the omap_ads7846_init

This seems OK to me until we have device tree bindings for
this.
