This series adds the support of LP1 suspend mode for Tegra. V3: * setting up CCLK burst policy to PLLX in LP1 resume code for Tegra114 too * moving the CCLKG burst policy resume code to tegra_cpu_car_ops for Tegra114 V2: * double confirm each patch can be built with all the combination of Tegra SoCs by bisect * and make sure the function is still OK with above testing Verified on Seaboard, Cardhu and Dalmore. And tested with THUMB2_KERNEL as well. P.S. A known issue on Dalmore, the LP1 resume may take 10 ~ 15 seconds due to the 792MHz BCT. It can't be reproduced on Seaboard or Cardhu. And the root cause of this is about the default settings of EMC registers that cause the DRAM can't leave self-refresh mode immediately. If you want to test with quick LP1 resume on Dalmore, I can provide another HACK for this.
