From: Eric van Tassell <evt@evtM17x.(none)>
Since my first attempt at doing this by analogy to what's already in
powerdebug(tree of sysfs files) was rejected because reviewers didn't
want to add a bunch more OMAP specific files to sysfs, I rewrote things
in userland.
There are a few basic chunks to the changes:
1) Add code to parse a CSV-like config file that defines a heirarchy
of whatever form you want where the leaves are fields in mmio
registers. Include decoders for the field values something easy to read
(ex: "off" instead of 0)
2) A code to build a tree that the powerdebug framework walks
from a CSV config file
3) A small bit of code to read the mmio regs via /dev/mem
4) One example config file each for Power & Voltage Domains.
It's all tested on OMAP4430(panda) but the config file mechanism
is completely general.
Eric van Tassell (7):
- add config files to define selected power domain and voltage domain
registers for OMAP4430 add delimi.* to parse config
files with clone of strchrnul
- add support for reading memory mapped I/O registers via /dev/mem
- add support to display fields of memory mapped I/O registers with
optional value decoding as defined by config files
- largest commit of this series. Provide an instance of the tree
abstraction used by powerdebug core that is built by parsing a
config file instead of walking a debugfs tree as, for example,
the sensor functionality does
- add display options for Voltage and Power domains - enable
extended display function call
- add options for power and voltage domains - call tree_mgr_new
to create the objects that implement them
- cleanup
