This series adds support for the MediaTek SCPSYS unit. The SCPSYS unit handles several power management related tasks such as thermal measurement, DVFS, interrupt filter and low level sleep control. The initial support only contains the generic power domain handling. This is needed to turn on power to the different power domains. The driver is quite straight forward now. Due to the lack of a better place I have put it to drivers/soc/mediatek. As the SCPSYS unit has several other tasks that also do not fit into some specific subsystem this probably is a good place for this driver. Please review, any input welcome. Sascha changes since v2: - Add missing include/linux/soc/mediatek/infracfg.h file - rename VDE -> VDEC, VEN -> VENC, DIS -> DISP and VEN2 -> VENC_LT to make the abbreviatons more clear - make of_device_id const - remove double loop - fix hunk in wrong patch - Fix order of domains. Some domains depend on other domains. Reorder the domains so that all domains can be turned on in order when CONFIG_PM is disabled. Also fixes earlier mixups in the domain array - Do not allow compilation as modules. pm_domains cannot be removed, so compilation as module is not that useful - reorder Kconfig items alphabetically - reorder #includes alphabetically - select MTK_INFRACFG instead of depending on it - Use only two clocks as dependencies for the domains. The previously used 5 clocks are not necessary as confirmed by the hardware designers - use 'genpd' as variable name for struct generic_pm_domain like done in other pm code changes since v1: - make MFG_ASYNC a subdomain of MFG_2D and MFG_2D a subdomain of MFG - Add (now hopefully properly) infracfg register handling again - Add clock handling - Fix on/off mixup in error message - Make readonly data const - Fix MODULE_LICENSE to GPL v2 changes since RFC: - add a commit log to driver patch - drop manipulating infracfg registers for now, can be added (properly) later - Add warning messages when errors occur - add NULL pointer check for kmalloc -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
