I am porting our drivers from MV 2.6.10 kernel to Kevin's git kernel. We have 3 different boards using DM355, with different gpio / pinmux setups. So far, our device drivers are modules which fiddle the pinmux registers directly.
I see in the git kernel that pinmux settings are defined in an array per-CPU (i.e. dm355.c) and the board file calls davinci_cfg_reg for those it wants setup. I'd like to build a single kernel which can support all of our board types, possibly detecting which it is running on by a parameter passed from u-boot. I could just update the hacks in our drivers, and our bootloader should setup the muxing right anyway, but if there is a supported "right" way to do this then I'd be interested to hear it. I like the debug warning messages if muxing is changed and feel like I should be using that code. At the moment I am thinking that I might want to split up davinci_cfg_reg into two functions so it's not hardwired to soc_info->pinmux_pins, and I could pass my own mux_config structs in. If this is of interest I can have a go at doing this and submitting the patch here. Any thoughts welcome. thanks. -- Jon Povey [email protected] Racelogic is a limited company registered in England.
