Subject: ARM: shmobile: r8a7740: add MERAM work-around

r8a7740 chip has lasting errata on MERAM buffer, and this patch adds
its work-around on setup-r8a7740.c
It solved CEU/VIO6C/2D-DMAC/VCP1/VPU5F/JPU/DISP memroy access error.

But MERAM driver can't control this issue,
since this work-around requires access to non-MERAM register address.
So, This it will be called as board specific code at this point.

Subject: ARM: shmobile: r8a7740: add FSI parent clock support

r8a7740 FSI can select its parent clock,
and its selection is dependent on platform board.

In order to enable FSI parent selection from platform board,
this patch adds its interface to clock framework.

This patch is based on v1.0 manual

Subject: ARM: shmobile: kzm9g: Support Real Time Clock

KZM-A9-GT board has RTC device r2025d at I2C channel 0
with slave address 0x64.

This patch enables reading and writing hardware real time clock on
KZM-A9-GT board. Interrupt is not yet supported.

How to test this patch using user space command.

Read RTC
 # hwclock -r

Copy system clock to RTC
 # hwclock -w

Shutdown and power off the board, and wait a while, then power on again.
Check RTC still keeps correct date.

Subject: ARM: shmobile: add common extra gpio functions

Current gpio frame work doesn't have the method to control
just pull up/down/free, but some SH-ARM boards need such kind of operation.
This patch adds common extra gpio functions for SH-ARM.

But these functions should be replaced by correct
gpio function in the future.

Subject: ARM: shmobile: use common DMAEngine definitions on r8a7740

This patch switch over to use common DMAEngine definitions,
and reduced a waste of code.

It is easy to understand if sh_dmae_pdata / sh_dmae_slave_config
settings are used defined value instead of direct value.

Subject: ARM: shmobile: sh73a0: add DMAEngine support for MPDMAC

Current shdmac can support MPDMAC (= sound DMA) on sh73a0.
This support reduce CPU load when sound was playback.

On v2.0 manual, MPDMAC MID/RID number were wrong.
This patch is using the number which seems correct.

Subject: ARM: shmobile: use common DMAEngine definitions on sh7372

This patch switch over to use common DMAEngine definitions,
and reduced a waste of code.

It is easy to understand if sh_dmae_pdata / sh_dmae_slave_config
settings are used defined value instead of direct value.

Subject: ARM: mach-shmobile: add 3.3V and 1.8V fixed regulators to mackerel

Drivers for several devices on mackerel, including all SDHI instances, the
MMCIF controller and the SMSC9220 ethernet chip use regulators to control
power supply to their devices. MMC drivers need to be able to at least
retrieve voltage values from supplying regulators, whereas the smsc911x
driver only enables and disables chip power supplies without further looking
at them. This patch adds two fixed voltage regulators to describe 1.8V and
3.3V supplies on the board and a dummy regulator for SMSC9220.

Convert the sh7372 A3SM power domain code to allow
waking up through INTCA and SYSC instead of only
relying on SYSC for wakeups. This allows us to
enter A3SM more or less regardless of the state
of the rest of the system.

Subject: ARM: shmobile: sh7372 A3SM CPUIdle support

Add CPUIdle support for the A3SM power domain on sh7372.

With this in place we can turn off more of the SoC during
run time and save power. Makes use of the recently introduced
sh7372 INTCA A3SM power domain wakeup support.

Subject: ARM: mach-shmobile: select the fixed regulator driver on several
 boards

On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

But current pfc-r8a7740 MSEL1CR 7bit setting was wrong.

Subject: ARM: shmobile: armadillo800eva: USB Func enables external IRQ mode

We can control renesas_usbhs driver as 2 way which are
autonomy mode and external IRQ trigger mode.

Autonomy mode is very easy settings for platform,
but it required USB power domain always ON,
since its connection/disconnection IRQ come from it.

If platform uses external IRQ trigger mode,
USB power domain can be OFF, since its
connection/disconnection IRQ come from external IRQ.

This patch enable external IRQ mode.
Now it is possible to add USB support on A4SP domain.

Because USB Func is controlled by external IRQ mode,

This patch enables it.

Armadillo800eva board switchs USB Host/Func by SW1.6,
So, the device to adds into domain is selected on this patch.

Subject: ARM: shmobile: sh7372: completely switch over to using pm-rmobile API

Now, all sh7372 platforms are switched over to use pm-rmobile base PM domain,
and no one is using original sh7372_pm_domain APIs.
We can remove these, switching has been fully completed.

Subject: ARM: mach-shmobile: r8a7740 generic board support via DT

Add generic DT board support for the r8a7740 SoC.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

At this point there is no interrupt controller support
in place but such code will be added over time when
proper IRQ domain support has been added to INTC.

Subject: ARM: shmobile: Take cpuidle dependencies into account correctly

The sh7372's cpuidle code uses cpu_suspend() and cpu_resume() in
its implementation of the .enter() callback for deeper C-states, so
make ARCH_SH7372 select ARM_CPU_SUSPEND if CPU_IDLE is set to satisfy
all of the build dependencies (it has to be selected for CONFIG_PM
as well for the system suspend handling).

Subject: ARM: shmobile: Fix build problem in pm-sh7372.c for unusual .config

If neither CONFIG_SUSPEND nor CONFIG_CPU_IDLE is set in the kernel
configuration file, build error occurs in
arch/arm/mach-shmobile/pm-sh7372.c.

Fix it by rearranging #ifdefs in that file to make the
definition of sh7372_suspend_init() depend only on
CONFIG_SUSPEND and the definition of sh7372_cpuidle_init()
depend only on CONFIG_CPU_IDLE.

Subject: ARM: shmobile: sh73a0: fixup RELOC_BASE of intca_irq_pins_desc

sh73a0 :: intca_irq_pins_desc irq table had conflict
from irq 552 to irq 557 before.
But the second controller was simply trampling the
first one by way of the -EEXIST case from irq_alloc_desc_at().

But now, we have irqdomain support from
1d6a21b0a672fb29b01ccf397d478e0541e17716
(sh: intc: initial irqdomain support)

The irqdomain code has simply tightened down the sanity checks and
error path. So, sh73a0 CPU board got some WARNING when booting now.
This patch fixup RELOC_BASE to solve this issue.

Subject: ARM: shmobile: armadillo800eva: fixup: sound card detection order

Since armadillo800eva has 2 sound cards,
and had reversed deferred probe order issue,
it was purposely registered in reverse order.

But it was solved by
1d29cfa57471a5e4b8a7c2a7433eeba170d3ad92
(driver core: fixup reversed deferred probe order)

armadillo800eva board is expecting that
FSI-WM8978 is the 1st, and FSI-HDMI is the 2nd sound card.
This patch fixes it up

Subject: ARM: shmobile: mackerel: fixup usb module order

renesas_usbhs driver can play role as both Host and Gadget.
In case of Gadget, it requires not only renesas_usbhs
but also usb gadget module (like g_ether).
So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time.

Because of this behavior,
Host port plays also Gadget role if kernel has both Host/Gadget support.

In mackerel case, from 0ada2da51800a4914887a9bcf22d563be80e50be
(ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd)
usb0 plays Gadget role, and usb1 plays Host role,
and current mackerel board probes as usb1 -> usb0.
Thus, 1st installed usb gadget module (like g_ether) will be
assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port).
It is very confusable for user.
This patch fixup usb modes probing order as usb0 -> usb1.
