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 2000-01-01 02:43:30 UTC (946694610) [ 4.753809] ### dt-test ### No testcase data in device tree; not running tests [ 4.791155] gps-power-domain: Power-off latency e Any ideas?
