I do not know regmap api, but I need interface which is easy readable from C
or shell scripts and which can read some registers (numbers 0-N).
These patches I written for Nokia N900. Now I need interface available in
kernel 2.6.28, which is only version working with Maemo (default N900 system).
Of course upstreaming *all* N900 drivers is needed, because I belive that one
day I will download vanilla kernel and run it on N900.
Anton Vorontsov, is simple debugfs interface (files - or only one file - which
have names of register numbers) acceptable for upstreaming (instead this
miscdevice with ioctl)?
