ARM: shmobile: r8a7779 Marzen multiplatform cleanup V3
[PATCH v3 01/04] ARM: shmobile: r8a7779: Generic SMP ops
[PATCH v3 02/04] ARM: shmobile: marzen-reference: Remove C board code
[PATCH v3 03/04] ARM: shmobile: Remove Marzen from shmobile_defconfig
[PATCH v3 04/04] ARM: shmobile: r8a7779: Cleanup header file
This series is simply resending the remaining r8a7779 multiplatform
cleanup patches. The code has not changed since V2:
[PATCH v2 00/06] ARM: shmobile: r8a7779 IRQ update and Marzen cleanup V2
With these patches applied the r8a7779 SoC gets DT-only multiplatform
support and old C board code for multiplatform gets removed.
The legacy r8a7779 Marzen code is not touched by this series, but
with these patches applied basic r8a7779 multiplatform SoC support
is done and only a few I/O devices are legacy-only.

Thanks, I have queued these up.
Please send a follow-up patch to address Geert's observation that
CONFIG_MACH_MARZEN should be removed from multi_v7_defconfig.

Unfortunately I have noticed a problem with patch 02/04,
and in particular the following portion of it:
--- a/arch/arm/mach-shmobile/Kconfig
+++ b/arch/arm/mach-shmobile/Kconfig
@@ -89,13 +89,6 @@ config ARCH_SH73A0
select ARCH_RMOBILE
select RENESAS_INTC_IRQPIN
-comment "Renesas ARM SoCs Board Type"
-
-config MACH_MARZEN
- bool "MARZEN board"
- depends on ARCH_R8A7779
- select REGULATOR_FIXED_VOLTAGE if REGULATOR
-
It appears that with the above applied REGULATOR_FIXED_VOLTAGE is
no longer set after make shmobile_defconfig which causes all sorts of
trouble as the fixed regulator is used by many devices on many boards.
I wonder if the best way forwards would be to simply enable
REGULATOR_FIXED_VOLTAGE in shmobile_defconfig (and probably
multi_v7_defconfig too).

Right, the regulator portion is indeed troublesome. And like you say,
it is needed for many boards including Gen2.

Yeah, I think so.

Thanks, I have sent a patch.
Review would be much appreciated.

Indeed,
"linux-config-from-dt arch/arm/boot/dts/r8a7779-marzen.dtb" says:
...
regulator-fixed is provided by:
drivers/regulator/fixed.c
needs CONFIG_REGULATOR_FIXED_VOLTAGE
...

Yes please.
Rule of thumb: check if the .configs generated from defconfigs have
changed after dropping a select.
