[PATCH 0/2] OMAP2+: misc. defconfig cleanups for 2.6.37

[Kevin Hilman]

A couple of small defconfig changes for 2.6.37 with the goal of working
towards a smaller default kernel image.

Kevin Hilman (2):
  OMAP2+: defconfig: disable CPUfreq
  OMAP2+: defconfig: modularize bluetooth, audio and WLAN

[PATCH 1/2] OMAP2+: defconfig: disable CPUfreq

[Kevin Hilman]

Disable CPUfreq since

1) is not yet supported in mainline, and
2) the current driver fails to suspend properly

[PATCH 2/2] OMAP2+: defconfig: modularize bluetooth, audio and WLAN

[Kevin Hilman]

In working towards a smaller default kernel, only devices used for
early boot should be built in.  Toward that end, build the following
as modules by default:

- bluetooth
- audio: ALSA, ASoC
- WLAN

Uncompressed kernel size comparison:

Thanks, adding both to omap-for-linus.
