For the starter only display controllers and devfreq devices are getting interconnect API support, others could be supported later on. The display controllers have the biggest demand for interconnect API right now because dynamic memory frequency scaling can't be done safely without taking into account bandwidth requirement from the displays. In particular this series fixes distorted display output on T30 Ouya and T124 TK1 devices. Changelog: v9: - Squashed "memory: tegra30-emc: Factor out clk initialization" into patch "tegra30: Support interconnect framework". Suggested by Krzysztof Kozlowski. - Improved Kconfig in the patch "memory: tegra124-emc: Make driver modular" by adding CONFIG_TEGRA124_CLK_EMC entry, which makes clk-driver changes to look a bit more cleaner. Suggested by Krzysztof Kozlowski. - Dropped voltage regulator support from ICC and DT patches for now because there is a new discussion about using a power domain abstraction for controlling the regulator, which is likely to happen. - Replaced direct "operating-points-v2" property checking in EMC drivers with checking of a returned error code from dev_pm_opp_of_add_table(). Note that I haven't touched T20 EMC driver because it's very likely that we'll replace that code with a common helper soon anyways. Suggested by Viresh Kumar. - The T30 DT patches now include EMC OPP changes for Ouya board, which is available now in linux-next.
