First lets get the UART working :) For Hikey's PM, related patches are ready for upstreaming [1]. Previously i'm waiting for merging mailbox driver, after that i plan to send out all DT patches to enable cpuidle/cpufreq/thermal/suspend in one going. Now pending on mailbox driver's merging. If you think it's necessary, i could send out patches to enable cpuidle firstly (actually now PSCI has been enabled yet); for cpufreq and thermal features, need wait until mailbox driver has been merged.
