[PATCH 01/26] ARM: shmobile: bockw: use regulator for MMCIF

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

When regulators are used with MMC devices, sh_mmcif_plat_data::ocr
is not needed, they can be removed from platform data.
This patch adds v3.3 regulator settings,
and moved fixed-dummy regulator registration position

[PATCH 10/26] ARM: shmobile: Initial r8a7791 and Koelsch multiplatform support

[Simon Horman]

From: Magnus Damm <damm@opensource.se>

Add Koelsch and r8a7791 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Koelsch board support exists in 3 flavors:
1) SHMOBILE_MULTI, MACH_KOELSCH - board-koelsch-reference.c (CCF + DT)
2) SHMOBILE, MACH_KOELSCH_REFERENCE - board-koelsch-reference.c (DT)
3) SHMOBILE, MACH_KOELSCH - board-koelsch.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.

[PATCH 08/26] ARM: shmobile: lager: set .debounce_interval

[Simon Horman]

From: Shinya Kuribayashi <shinya.kuribayashi.px@renesas.com>

In R-Car GPIO hardware block, 'chattering removal' feature can be
enabled on GPIO-n-[3:0] pins, but it's not supported on rest of pins
GPIO-n-[31:4].

Set an appropriate debounce interval, instead.  We could confirm that
spurious/unnecessary GPIO interrupts are prevented by this settings.

[PATCH 18/26] ARM: shmobile: Use ->init_late() on Lager

[Simon Horman]

From: Magnus Damm <damm@opensource.se>

Hook in shmobile_init_late() on Lager V2. This enables some PM
related things like CPUIdle and Suspend-to-RAM.

With this patch applied it is possible to use Suspend-to-RAM:
# echo enabled > /sys/class/tty/ttySC6/power/wakeup
# echo mem > /sys/power/state
(wake by sending a character on the serial console)

[PATCH 20/26] ARM: shmobile: mackerel: clk_round_rate() can return a zero to indicate an error

[Simon Horman]

From: Paul Walmsley <pwalmsley@nvidia.com>

Treat both negative and zero return values from clk_round_rate() as
errors.  This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather than a
signed type, since some clock sources can generate rates higher than
(2^31)-1 Hz.

Eventually, when calling clk_round_rate(), only a return value of zero
will be considered a error.  All other values will be considered valid
rates.  The comparison against values less than 0 is kept to preserve
the correct behavior in the meantime.

[PATCH 23/26] ARM: Kconfig: Mention Renesas ARM SoCs instead of SH-Mobile

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Only the SH-Mobile product name is mentioned in the Kconfig descriptions
and help texts. This makes it difficult for external engineers working
on other Renesas platforms to find upstream platform support as the
combination of the SH-Mobile name and using the product number proved an
effective method of concealment.

Replace the "SH-Mobile" name with "Renesas ARM SoCs" in all the related
descriptions, help texts and comments.

[PATCH 26/26] ARM: shmobile: lager: add gpio/fixed regulator for SDHI

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Fixed regulator is used for SDHI0/2 Vcc.
We should use da9063 driver for Vccq,
but, it doesn't have regulator support at this point.
This patch uses gpio-regulator for it as quick-hack.
