Add a power domain framework/uclass Many SoCs allow power to be applied to or removed from portions of the SoC (power domains). This may be used to save power. This API provides the means to control such power management hardware. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

power: Add power domain driver for i.MX8 Add the power domain DM driver for i.MX8, that it depends on the DTB power domain trees to generate the power domain provider devices. Users need to add power domain trees with property "compatible = "nxp,imx8-pd";" When power on a PD device, the driver will power on its ancestor PD devices in power domain tree. When power off a PD device, the driver will check its child PD devices first. Only if all child PD devices are off, then power off the current PD device. Then the driver checks sibling PD devices. If sibling PD devices are off, then it will power off parent PD device. There is no counter maintained in this driver, but a state to hold current on/off state. So the request and free functions are empty. The power domain implementation in i.MX8 DTB set the "#power-domain-cells" to 0, so there is no ID binding with each PD device. We don't use "id" variable in struct power_domain. At the same time, we have to set of_xlate to empty to bypass standard of_xlate in uclass driver.

power: domain: Add the VPU Power Domain driver The Amlogic Meson SoCs embeds a specific Power Domain dedicated to the Video Processing Unit. This patch implements support for this power domain in preparation of the future support for the Video display support in U-Boot. This driver will depend on changes in the clock driver to handle the setup of the VPU and VAPB clocks configured from DT using assigned-clocks entries.

actually doing anything beyond a little error checking.
power domain: add Tegra186 driver In Tegra186, SoC power domains are manipulated using IPC requests to the BPMP (Boot and Power Management Processor). This change implements a driver that does that.

power domain: Introduce TI System Control Interface (TI SCI) power domain driver Some TI Keystone 2 and K3 family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and the Device Management and Security Controller on AM65x SoCs) that manage the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a power domain driver that communicates to the system controller over the TI SCI protocol for performing power management of various devices present on the SoC. Various power domain functionalities are achieved by the means of different TI SCI device operations provided by the TI SCI framework. This code is loosely based on the drivers/soc/ti/ti_sci_pm_domains.c driver of the Linux kernel.
