Only couple drivers need to get the -ENODEV error code and majority of drivers need to explicitly initialize the performance state. Add new common helper which sets up OPP table for these drivers.

Document sub-nodes which describe Tegra SoC clocks that require a higher voltage of the core power domain in order to operate properly on a higher clock rates. Each node contains a phandle to OPP table and power domain.

The root PLLs and system clocks don't have any specific device dedicated to them, clock controller is in charge of managing power for them.

Add runtime PM and OPP support to the Host1x driver. For the starter we will keep host1x always-on because dynamic power management require a major refactoring of the driver code since lot's of code paths are missing the RPM handling and we're going to remove some of these paths in the future.

The HDMI on Tegra belongs to the core power domain and we're going to enable GENPD support for the core domain. Now HDMI driver must use OPP API for driving the controller's clock rate because OPP API takes care of reconfiguring the domain's performance state based on HDMI clock rate. Add OPP support to the HDMI driver.

CDMA must be stopped before hardware is suspended. Add channel stopping to RPM suspend callback. Add system level suspend-resume callbacks.

Runtime PM initialization is moved to host1x client init phase because RPM callback now uses host1x channel that is available only when host1x client is registered.

The SPI on Tegra belongs to the core power domain and we're going to enable GENPD support for the core domain. Now SPI driver must use OPP API for driving the controller's clock rate because OPP API takes care of reconfiguring the domain's performance state in accordance to the rate. Add OPP support to the driver.

Memory access must be blocked before hardware reset is asserted and before power is gated, otherwise a serious hardware fault is inevitable. Add reset for memory clients to the GR2D, GR3D and Host1x nodes.

MPE, VI, EPP and ISP were never used and we don't have drivers for them. Since these modules are enabled by default in a device-tree, a device is created for them, blocking voltage scaling because there is no driver to bind, and thus, state of PMC driver is never synced. Disable them.
