Subject: soc/tegra: fuse: Add Tegra186 support

Tegra210 and Tegra186 are mostly compatible from a fuses point of view.
However, speedo support is implemented in the BPMP firmware, hence the
implementation needs to be skipped in the fuses driver.

Subject: soc/tegra: fuse: Move register mapping check

The tegra_read_chipid() function can be called from places other than
tegra_get_chip_id(), so the check for a valid mapping of the MISC
registers needs to be moved to tegra_read_chipid() to catch all
potential accesses.

Subject: soc/tegra: fuse: Warn if accessing unmapped registers

If the FUSE registers are accessed but the region is not mapped, warn
and return 0. This potentially catches hard to diagnose bugs because the
accesses happen before any kernel log output.

Subject: soc/tegra: fuse: Add Tegra186 chip ID support

The register region containing chip ID information has been relocated in
Tegra186 and changed in backwards-incompatible ways. Add a compatible
string to allow the driver to make the distinction.

Subject: soc/tegra: pmc: Parameterize driver

Parameterize some aspects of the driver in preparation for Tegra186 PMC
support. Initially the Tegra186 driver had been split off into an extra
driver, but it turns out the backwards-compatibility break isn't as bad
as originally assumed, so with a little parameterization the same code
can be used to keep supporting all SoC generations.

Subject: soc/tegra: pmc: Consolidate Tegra186 support

Move Tegra186 support to the consolidated PMC driver to reduce some of
the duplication and also gain I/O pad functionality on the new SoC as a
side-effect.

Subject: soc: renesas: rcar-sysc: Keep wakeup sources active during system
 suspend

If an R-Car SYSC slave device is part of the CPG/MSTP or CPG/MSSR Clock
Domain and to be used as a wakeup source, it must be kept active during
system suspend.

Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source.  However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.

Note that this will only affect devices configured as wakeup sources.

Subject: soc: mediatek: extend bus protection API

MT2712 add "set/clear" bus control register to each control register set
instead of providing only one "enable" control register, we could avoid
the read-modify-write racing by declaring "bus_prot_reg_update" as "false"
in scp_soc_data or declaring as "true" to use the legacy update method.
By improving the mtk-infracfg bus protection implementation to
support set/clear bus protection control method by IC configuration.

FUSE driver doesn't configure DMA channel properly, because of it DMA
transfer is never issued and tegra20_fuse_read() always return 0x0.

Subject: soc/tegra: fuse: Explicitly request DMA channel from APB DMA driver

Currently fuse driver requests DMA channel from an arbitrary DMA device,
it is not a problem since there is only one DMA provider for Tegra20 yet,
but it may become troublesome if another provider will appear.

Subject: soc: Add SoC driver for Gemini

This adds an SoC driver for the Gemini. Currently there
is only one thing not fitting into any other framework,
and that is the bus arbitration setting.

All Gemini vendor trees seem to be setting this register to
exactly the same arbitration so we just add a small code
snippet to do this at subsys_init() time before any other
drivers kick in.
