Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware User's Manual rev. 0.53E. Hence remove it from the power area table when not running on ES1.x. This is in line with the goal to: 1. Support both the ES1.x and ES2.0 SoC revisions in a single binary for now, 2. Make it clear which code supports ES1.x, so it can easily be identified and removed later, when production SoCs are deemed ubiquitous. Signed-off-by:

The same SoC may have different power areas, depending on SoC revision. One option is to use different sets of power area tables for each SoC revision. However, if the differences are small, it is much more space-efficient to have a single set of tables, and fix those up at runtime instead. Hence provide a helper to NULLify power areas that do not exist on some revisions (NULLified power areas are skipped during the registration phase), and support for an optional initialization callback to e.g. fix up power area tables.

The r8a7795 SYSC driver manages PM Domains, and thus is initialized from an early_initcall(). However, this means the driver cannot check the SoC revision, as the SoC device hasn't been registered yet. Change renesas_soc_init() from a core_initcall() to an early_initcall() to fix this (renesas-soc.o is listed before rcar-sysc.o in the Makefile). Signed-off-by:

On i.MX6QP, due to hardware erratum ERR009619, the PRE clocks may be stalled during the power up sequencing of the PU power domain. As this may lead to a complete loss of display output, the recommended workaround is to keep the PU domain enabled during normal system operation. Implement this by rejecting the domain power down request on the affected SoC. Signed-off-by:

This moves the ICST clock divider helper library from arch/arm/common to drivers/clk/versatile so it is maintained with the other clock drivers. We keep the structure as a helper library intact and do not fuse it with the clk-icst.c Versatile ICST clock driver: there may be other users out there that need to use this library for their clocking, and then it will be helpful to keep the library contained. (The icst.[c|h] files could just be moved to drivers/clk/lib or a similar location to share the library.) Acked-by:

Introduce a ti_sci_pm_domains driver to act as a generic pm domain provider to allow each device to attach and associate it's ti-sci-id so that it can be controlled through the TI SCI protocol. This driver implements a simple genpd where each device node has a phandle to the power domain node and also must provide an index which represents the ID to be passed with TI SCI representing the device using a single phandle cell. The driver manually parses the phandle to get the cell value. Through this interface the genpd dev_ops start and stop hooks will use TI SCI to turn on and off each device as determined by pm_runtime usage. Reviewed-by:

Add a generic power domain implementation, TI SCI PM Domains, that will hook into the genpd framework and allow the TI SCI protocol to control device power states. Also, provide macros representing each device index as understood by TI SCI to be used in the device node power-domain references. These are identifiers for the K2G devices managed by the PMMC.

There is no reason that a platform genpd driver registered using of_genpd_add_provider_simple needs to be constrained to having no cells in the "power-domains" phandle. Currently the genpd framework will fail if any arguments are passed with for a simple provider but the framework does not actually care, so remove the check for phandle argument count. This will allow greater flexibility for genpd providers to use their own arguments that are passed in the phandle and interpret them however they see fit. Acked-by:

Tegra132 and Tegra210 support the flowctrl module and so add initial support for these devices. Please note that Tegra186 does not support the flowctrl module, so update the initialisation function such that we do not fall back and attempt to map the 'hardcoded' address range for Tegra186. Furthermore 64-bit Tegra devices have always had the flowctrl node defined in their device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra devices. Signed-off-by:

The flowctrl driver is required for both ARM and ARM64 Tegra devices and in order to enable support for it for ARM64, move the Tegra flowctrl driver into drivers/soc/tegra. By moving the flowctrl driver, tegra_flowctrl_init() is now called by via an early initcall and to prevent this function from attempting to mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()' is also added.

The Makefiles currently controlling compilation of this code is: drivers/soc/tegra/Makefile:obj-y += fuse/ drivers/soc/tegra/fuse/Makefile:obj-y += fuse-tegra.o ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit.
