Subject: ARM: dts: omap3-beagle-xm: Add fixed 26MHz clock as fck for twl
X-Git-Tag: v4.18-rc1~50^2~48^2~11
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bcddb927fe24469badd4c98042593f59d5cf2c04;p=thirdparty%2Fkernel%2Fstable.git

ARM: dts: omap3-beagle-xm: 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
