Adds CPU/core voltage bump before system is rebooted. 2. Adds new devm_tegra_core_dev_init_opp_table() helper and switches Tegra memory drivers to use it. 3. Adds compile-testing support to the Tegra memory drivers. 4. Adds Tegra SoC core power domain support. Changelog: v4: - Fixed misplaced prototypes of tegra_pmc_core_domain_state_synced(), which I noticed only after sending out v3. This fixes building with !CONFIG_PM_SLEEP. v3: - Dropped "Detach coupled regulator before coupling count is dropped" patch that was added in v2 since it missed regulator locking and it should be more reasonable to add a new generic hook for syncing before detaching. For now it's optional to sync Tegra SoC regulators before detaching since it's not something that happens in practice, hence it's more optimal to simply drop that feature. - Added more stubs for T210 clk driver which should fix compile-testing problem reported for v2 by kernel robot. - Added COMMON_CLK for COMPILE_TEST of memory drivers since for today the problem of compile-testing of legacy platforms that use HAVE_LEGACY_CLK isn't solved, we will be able to remove it after fixing the legacy platforms. - Factored out new PMC driver state syncing feature into a separate patch "pmc: Add driver state syncing", which was requested by Ulf Hansson in a review comment to v2. - Added r-b from Ulf Hansson to the PMC binding-update patch that he gave to v2. v2: - Added more clk stubs that should fix build error reported by the kernel bot to v1 for the T210 memory driver. - Added r-b from Krzysztof Kozlowski to the memory patches. - Added back voltage restore on detaching of coupled regulators to the T20 regulator coupler which previously got missed by accident. - Added new patch: regulator: core: Detach coupled regulator before coupling count is dropped It fixes skipped voltage balancing on detaching of regulators which I happened to notice due to the recent regression of the MAX77620 driver that made driver to re-probe and detach coupled regulators. v1: - Merged previous patches into this single series. - Added ack from Rob Herring to the core domain DT binding patch. - Implemented suggestions that were given by Krzysztof Kozlowski: - Factored out soc_is_tegra() stub into standalone patch. - Updated tags of the "Fix compilation warnings on 64bit platforms" patch, added reported-by from lkp robot and removed suggested-by from Nathan Chancellor. - Switched to use use BIT() macro. - Added r-b from Krzysztof Kozlowski to "Enable compile testing for all drivers" patch. - Added r-b from Nathan Chancellor. - Dropped voltage floor/ceiling from devm_tegra_core_dev_init_opp_table() since only memory drivers now need to initialize voltage vote and they don't need floor/ceil. This was suggested by Viresh Kumar.
