Subject: ARM: dts: omap3-gta04: Add fixed 26MHz clock as fck for twl
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0a6fd4ee8f3245fc758c04ecff14075aef80d374;p=linux.git

ARM: dts: omap3-gta04: Add fixed 26MHz clock as fck for twl

The board uses 26MHz oscillator for the twl4030 HFCLK.
This way we will not depend on the bootloader to configure the
CFG_BOOT:HFCLK_FREQ
