X-Git-Tag: v2009.03-rc1~2^2^2~4
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=288f3cd912918b97919d13b6f7fb13fbddf74d68;p=u-boot

OMAP3: Overo: Clean up pin mux and GPIO configuration

* Make Overo GPIO114 an input for touchscreen PENDOWN
* Make Overo GPIO144-147 readable
* Make Overo EHCI pinmux match beagle rev c setup
* Adjust pinmux for SMSC911X network chip support
* Remove unnecessary GPIO setup
* Fix merge error in Makefile
