soc: renesas: r8a77990-sysc: Fix initialization order of 3DG-{A,B}

2019-12-13T07:52:29+00:00

[ Upstream commit b0d7fbf8b174168c580bb310964c3c809e5569a9 ]

The workaround for the wrong hierarchy of the 3DG-{A,B} power
domains on R-Car E3 ES1.0 corrected the parent domains.
However, the 3DG-{A,B} power domains were still initialized and powered
in the wrong order, causing 3DG operation to fail.

Fix this by changing the order in the table at runtime, when running on
an affected SoC.

soc: renesas: r8a77980-sysc: Correct A3VIP[012] power domain hierarchy

2019-12-13T07:52:17+00:00

[ Upstream commit 160bfa7c724b348a90a12dd9694f351927a15b8e ]

The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018)
renamed the A3VIP power domain on R-Car V3H to A3VIP0, and clarified the
power domain hierarchy for the A3VIP[012] power domains.

As the definition for the A3VIP0 domain is not yet used from DT, it can
just be renamed.

[ Upstream commit 97473bc85b22ac610b1810b6a9a4669a6cb0b7b0 ]

The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018)

A2DP1.

The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018)
renamed the A2IR2 and A2IR3 power domains on R-Car V3M to A2DP resp.
A2CN.

As these definitions are not yet used from DT, they can just be renamed.

While at it, fix the indentation of the A3IR definition.

drivers: soc: Allow building the amlogic drivers without ARCH_MESON

[ Upstream commit 41bb5769b7f4b7a85e4b92c37429228279b4f569 ]

The current condition makes it difficult to compile the amlogic/
drivers with COMPILE_TEST, or without ARCH_MESON in general.

Fixes kbuild errors with patch series that depend on drivers in that
directory, for instance the meson video decoder.

soc: bcm: brcmstb: Fix re-entry point with a THUMB2_KERNEL

[ Upstream commit fb14ada11d62fb849fc357a25ef8016ba438ba10 ]

When the kernel is built with CONFIG_THUMB2_KERNEL we would set the
kernel's resume entry point to be a function that is already built as
Thumb-2 code while the boot agent doing the resume is in ARM mode, so
this does not work. There is a header label defined: cpu_resume_arm
which we can use to do the switching for us.

active request and during invalidate of the sleep and wake TCS.
