[ACTIVITY] (Linus Walleij) 2011-11-26 - 2011-12-02

[Linus Walleij]

== Linus Walleij linusw ==

=== Highlights ===

* Sent out v5 of the pin config patch series after some further
  discussion: as usual nVidia provide the most challenging
  feedback.

* Discussed pinmux maps proliferation with Arnd Bergmann
  and Haojian Zhuang (PXA pinmux maintainer) and came up
  with patches to address the issue of being able to tag
  pinmux maps as __initdata so they are discarded after boot.
  We also added the possibility to incrementally add several
  sets of pinmux mappings, doing away with the "once and
  for all" approach to registering maps.

* Discussed DT mappings to pin controllers with Stephen
  Warren and Tony Lindgren. No consensus reached.

* Ux500 mainlining since too little is happening:
  - AB8500 RTC patches iterated with Andrew Morton and
    accepted into his tree.
  - Fixed up patches for some movearound in the abx500
    include headers directory.
  - Clean-up and forward-ported AB5500 high voltage
    LEDs driver.
  - The two latter will be sent off ASAP, just awaiting some
    optional internal feedback.

* Read and commented on a few patches on various mailing
  lists to keep uptodate.

=== Plans ===

* Drive generalization of Nomadik GPIO
 by using the pinctrl framework.
 drivers/gpio/gpio-nomadik.c

* Test the PL08x patches on the Ericsson Research
 PB11MPCore and submit platform data for using
 pl08x DMA on that platform.

* Look into other Ux500 stuff in need of mainlining...
  like the HWMON stuff.

=== Issues ===

* Risk of pin controller subimplementations being delayed due
  to the time it takes to reach consensus. Would be good if
  the people who really need the pin config stuff got involved
  with the discussion and start ACK:ing patches when they
  like them, and tell me what I'm doing wrong and if they agree
  with the critics. Active participation in discussions would be
  appreciated. NOTE: I'm worthless in soft motivational-aspects
  of leadership (get people to actively do stuff). The only person
  I can motivate to discuss pin control is myself...

Thanks,
