Hi, fref_xtal_clk is a clock going out from omap5 chip, sourced directly from the system oscillator. fref_xtal_clk can be used to provide a high frequency clock to some external component, in omap5 setups, typically twl6040 audio chip. Testing done (number of boards on the test farm are currently out of order): am335x-evm : BOOT FAIL! am335x-evmsk : boot am37x-evm : boot am437x-sk : boot am43x-epos-evm : boot am437x-gp-evm : boot am57xx-evm : boot omap3-beagle-xm : boot am335x-boneblack: boot am335x-bone : boot dra72x-evm : boot dra7xx-evm : boot omap5-uevm : boot On omap5, also verified that the new clock node appears under debugfs. am335x-evm failure is due to inability to mount NFS rootfs on the board in question the boot goes fine until that. There are some issues with the u-boot installed on this board currently. -Tero -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
