Good to have the warning splat silenced.
This series brings initial support for memory interconnect to Tegra20, Tegra30 and Tegra124 SoCs. 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: v11: - Added acks from Georgi Djakov. - CC'ed devicetree@vger.kernel.org in order to make the dt-bindings patch ("Document opp-supported-hw property") visible to the DT maintainers. - Rebased on a recent linux-next, note that some of v10 DT patches were already applied by Thierry into tegra tree, as well as one devfreq patch which removed the older tegra20-devfreq driver was applied by Chanwoo Choi to the devfreq tree. - Note that patch "memory: tegra20: Support hardware versioning and clean up OPP table initialization" fixes the noisy (but harmless) warning which happens because DT patches were applied before the code changes. This problem was spotted in current linux-next by Jonathan Hunter, hence could be worthwhile to pick up this patch for the v5.11. v10 - In a longer run it will be much nicer if we could support EMC hardware versioning on Tegra20 and it's not late to support it now. Hence I added these new patches: dt-bindings: memory: tegra20: emc: Document opp-supported-hw property memory: tegra20: Support hardware versioning and clean up OPP table initialization - Removed error message from tegra30-devfreq driver about missing OPP properties in a device-tree because EMC driver already prints that message and it uses OPP API error code instead of checking DT directly, which is a more correct way of doing that. 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.
