[PATCH 1/9] arm64: renesas: Enable GPIOLIB to allow GPIO driver selection

[PATCH 1/9] arm64: renesas: Enable GPIOLIB to allow GPIO driver selection

[Simon Horman]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

The R-Car GPIO driver cannot be enabled when Renesas SoC's ARCH configs
(ARCH_RENESAS, ARCH_R8A7795, ARCH_R8A7796 and ARCH_R8A77965) are enabled
only.

As GPIOs are a critical resource for proper operation on Renesas
platforms, this patch selects GPIOLIB, just like is done for other SoC
vendors, and on Renesas arm32 SoCs.

[PATCH 2/9] ARM: shmobile: Restrict SCU support to SoCs that have it

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Currently support for the ARM Cortex-A9 Snoop Control Unit is included
unconditionally, while only Renesas multicore Cortex-A9 SoCs have this
kind of SCU.

This decreases kernel image size by ca. 300 bytes on SoCs without such
an SCU.

[PATCH 5/9] ARM: shmobile: Hide ARCH_RZN1 to improve consistency

From: Geert Uytterhoeven <geert+renesas@glider.be>

Unlike all other family-specific Kconfig symbols for Renesas ARM SoCs,
ARCH_RZN1 is user-visible.  As this symbol is already selected by the
SoC-specific ARCH_R9A06G032 symbol, there is no need for that.

Hide ARCH_RZN1 from the user, and move it up, where all other
family-specific Kconfig symbols live.  Drop the select of CPU_V7, as
this is already implied by the dependency of ARCH_RENESAS on
ARCH_MULTI_V7.

[GIT PULL] Renesas ARM Based SoC Updates for v4.21

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC updates for v4.21.


Usually I separate SoC changes for ARM and arm64 into separate branches.
On this occasion I have applied them to a single branch and pull request.
The reason for this is that moving SoC Konfig symbols for both ARM and
arm64 creates a dependency and a combined branch is a clean way to resolve
this.

If separate branches are required then I propose deferring the movement
of ARM (but not arm64) SoC Kconfig symbols to v4.22.


The following changes since commit 651022382c7f8da46cb4872a545ee1da6d097d2a:

[PATCH 6/9] arm64: renesas: Move SoC Kconfig symbols to drivers/soc/renesas/

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for
Renesas SoCs, while other vendors have only a single Kconfig symbol.

Increase consistency with other vendors by moving the SoC-specific
Kconfig symbols to drivers/soc/renesas/Kconfig.

Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by
introducing a family-specific Kconfig symbol for R-Car Gen3
(ARCH_RCAR_GEN3), which enables family-specific hardware features.
While so far only a single family (R-Car Gen3 and derivatives) of
Renesas arm64 SoCs is supported by Linux, this will make it easier
to add support for other SoC families later.

[GIT PULL] Renesas ARM Based SoC Updates for v4.21

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC updates for v4.21.


Usually I separate SoC changes for ARM and arm64 into separate branches.
On this occasion I have applied them to a single branch and pull request.
The reason for this is that moving SoC Konfig symbols for both ARM and
arm64 creates a dependency and a combined branch is a clean way to resolve
this.

If separate branches are required then I propose deferring the movement
of ARM (but not arm64) SoC Kconfig symbols to v4.22.


The following changes since commit 651022382c7f8da46cb4872a545ee1da6d097d2a:

[PATCH 6/9] arm64: renesas: Move SoC Kconfig symbols to drivers/soc/renesas/

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for
Renesas SoCs, while other vendors have only a single Kconfig symbol.

Increase consistency with other vendors by moving the SoC-specific
Kconfig symbols to drivers/soc/renesas/Kconfig.

Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by
introducing a family-specific Kconfig symbol for R-Car Gen3
(ARCH_RCAR_GEN3), which enables family-specific hardware features.
While so far only a single family (R-Car Gen3 and derivatives) of
Renesas arm64 SoCs is supported by Linux, this will make it easier
to add support for other SoC families later.

[PATCH 7/9] ARM: shmobile: Move SoC Kconfig symbols to drivers/soc/renesas/

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

For consistency with arm64, where vendors have a single Kconfig symbol
in arch/arm64/Kconfig.platforms.

[PATCH 8/9] ARM: shmobile: R-Mobile: Clean up struct rmobile_pm_domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Commit 59b89af1d5551c12 ("ARM: shmobile: sh7372: Remove Legacy C
SoC code") removed the last user of the rmobile_pm_domain.resume()
callback.

Commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1") removed the last user of the rmobile_pm_domain.no_debug
flag and of the "pm-rmobile.h" header file (outside the actual driver).

Hence remove no longer used rmobile_pm_domain members, and absorb the
header file into the driver.

[PATCH 8/9] ARM: shmobile: R-Mobile: Clean up struct rmobile_pm_domain

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Commit 59b89af1d5551c12 ("ARM: shmobile: sh7372: Remove Legacy C
SoC code") removed the last user of the rmobile_pm_domain.resume()
callback.

Commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1") removed the last user of the rmobile_pm_domain.no_debug
flag and of the "pm-rmobile.h" header file (outside the actual driver).

Hence remove no longer used rmobile_pm_domain members, and absorb the
header file into the driver.

[PATCH 9/9] ARM: shmobile: R-Mobile: Move pm-rmobile to drivers/soc/renesas/

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

The pm-rmobile driver is really a driver for the System Controller
(SYSC) found in R-Mobile SoCs.  An equivalent driver for R-Car SoCs is
already located under drivers/soc/renesas/.

Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and rename it to rmobile-sysc.

Enable compile-testing on non-ARM and non-R-Mobile SoCs.
