Dear Marek Vasut,
I'm submitting hereby the initial code for the driver model. This is a RFC patch, please give it a spin and scream :-)
The GPIO api should now use the new approach on the sandbox target. There's also "dm" command, that allows dumping the driver tree.
Expanding CC ... guys, please start ripping us to shreds :-)
Marek Vasut (5): dm: sandbox: Add necessary linker sections dm: sandbox: Add necessary GD sections dm: REMOVE: sandbox binding experiment dm: gpio: Add draft GPIO core and convert sandbox to use it dm: Add "dm dump" command
Pavel Herrmann (2): dm: Add skeleton support for cores and drivers dm: add dummy demo driver and core
