This isn't working for me.
Testing linus master e99cfa2d0634881b8a41d56c48b5956b9a3ba162 plus:
ARM: dts: exynos4: add port sub-nodes to exynos usb host modules
ARM: dts: exynos4412-odroidx: enable common hardware blocks
ARM: dts: exynos4412-odroidx: add support for USB (phy, host, device)
ARM: dts: refactor Odroid DTS file and add support for Odroid X2 and U2/U3
Testing on ODROID-U2.
I apply the first patch here (clk: samsung: exynos4: Add missing
CPU/DMC clock hierarchy) and things continue to work. Now when I add
the second patch "clk: samsung: exynos4: Add CLKOUT clock hierarchy"
boot hangs at:
[ 4.753740] s3c-rtc 10070000.rtc: setting system clock to

[ 4.753809] ### dt-test ### No testcase data in device tree; not
running tests
[ 4.791155] gps-power-domain: Power-off latency e
Any ideas?
Thanks
Daniel
