Device Tree

  • Added device tree support for imx6 clock based common-clk-v3 series
    • and Grant's device tree binding series (RFC).
  • Addressed Sascha's comments on imx6 clock DT support.
  • Added mc13892-regulator device tree support based on Rajendra's
    • series which has been applied on regulator/for-next.

Consolidation and cleanup

  • Reviewed Mike's common-clk-v3 series.


  • Collected mxs saif-recording patches.

  • Knowledge sharing session on DT.
  • Further planning for DT on Snowball.

Rajendra Nayak <rnayak>


  • Regulator core DT support patches pulled in by Mark Brown.
    • Pushed to linux-next.
  • Posted v2 of omap-serial DT support series with all outstanding
    • issues fixed.
  • Working on pinconf support (pull up/down configuration) for OMAP
    • based on the latest v3 pinconf-core support series from LinusW. Should have patches out early this week.
  • Working on moving the omap clock data into DT based on the latest
    • clock bindings from Grant. Mike Turquette already has a port of omap clock framework to use common clock infrastructure.


  • Repost TWL regulator support. (Still waiting for a repost of omap
    • i2c/twl DT support patches)
  • Work on pinconf/pinmux support for OMAP and align with Tony who is
    • working on moving the data into DT and creating function/pin-gp information dynamically.
  • Other driver DT support for OMAP.

Activity Summary

  • Reviewing of Pawel's versatile express patches and related discussions
  • Proposed a more unified approach for manipulating instruction opcodes
    • inside the kernel in the presence of multiple ISA and endianness cofigurations.
  • Started to sketch out a unified unwind/backtrace interface for the
    • ARM kernel (or, possibly, the whole kernel) in response to upstream discussions regarding ftrace -- ftrace doesn't support unwind tables, but really there should be a unified interface so nobody has to care.
  • Reported a couple of binutils bugs


  • Move miscellaneous outstanding DT issues (bindings, drivers) forward.
