afzal mohammed 5497fce735 sh: Replace setup_irq() by request_irq()
request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.

setup_irq() was required in older kernels as the memory allocator was not
available during early boot.

Hence replace setup_irq() by request_irq().

Christoph Hellwig 4bdc0d676a remove ioremap_nocache and devm_ioremap_nocache

days, so remove the additional ioremap_nocache interface.

Christoph Hellwig cdfee56232 driver core: initialize a default DMA mask for platform device
We still treat devices without a DMA mask as defaulting to 32-bits for
both mask, but a few releases ago we've started warning about such
cases, as they require special cases to work around this sloppyness.
Add a dma_mask field to struct platform_device so that we can initialize
the dma_mask pointer in struct device and initialize both masks to
32-bits by default, replacing similar functionality in m68k and
powerpc.  The arch_setup_pdev_archdata hooks is now unused and removed.

Note that the code looks a little odd with the various conditionals
because we have to support platform_device structures that are
statically allocated.

Randy Dunlap acaf892ecb sh: fix multiple function definition build errors
Many of the sh CPU-types have their own plat_irq_setup() and
arch_init_clk_ops() functions, so these same (empty) functions in
arch/sh/boards/of-generic.c are not needed and cause build errors.

If there is some case where these empty functions are needed, they can
be retained by marking them as "__weak" while at the same time making
builds that do not need them succeed.

Fixes these build errors:

arch/sh/boards/of-generic.o: In function `plat_irq_setup':
(.init.text+0x134): multiple definition of `plat_irq_setup'
arch/sh/kernel/cpu/sh2/setup-sh7619.o:(.init.text+0x30): first defined here

spi: sh-msiof: Convert to use GPIO descriptors
Convert GPIO chip selects in the Renesas MSIOF SPI driver from legacy
GPIO numbers to GPIO descriptors.

Notes:
  - The board file for the SH7724-based Ecovec24 development board now
    registers a GPIO descriptor lookup, instead of passing a GPIO number
    through controller_data,
  - sh_msiof_get_cs_gpios() must release all GPIOs, else
    spi_get_gpio_descs() cannot claim them during SPI controller
    registration.

Linus Walleij 01dc79cd6f
regulator: fixed/gpio: Pull inversion/OD into gpiolib
This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.

This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

Arnd Bergmann 19f48591e6 sh: remove board_time_init() callback
The only remaining user of board_time_init() is the of-generic
machine, and that just calls the global timer_init() function.
Calling that one has no effect on non-DT platforms, so we can
simply call it unconditionally in place of board_time_init().

Arnd Bergmann 09e81263e5 sh: sh03: rtc: push down rtc class ops into driver
The SH RTC support has an extra level of indirection to provide
either the old read_persistent_clock/update_persistent_clock
interface or the rtc-generic device for hctosys/systohc.

By removing the indirection and always using the RTC_CLASS interface,
we can avoid the lossy double conversion between rtc_time and timespec,
so we end up supporting the entire range of 'year' values, and clarifying
the rtc_set_time callback.

I did not change the behavior of sh03_rtc_settimeofday(), which keeps
just updating the seconds/minutes by calling set_rtc_mmss(), this
could be improved if anyone cares. Also, the file should ideally be
moved into drivers/rtc and not use rtc-generic.

Both do the same thing for dreamcast, so we can do away with the

Linus Walleij faed930306 mmc: host: tmio: Use GPIO descriptors
The TMIO MMC driver was passing global GPIO numbers around for
card detect. It turns out only one single board in the kernel
was actually making use of this feature so it is pretty easy
to convert the driver to use only GPIO descriptors.

The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is
what they are, and since we can now rely on the descriptors
to have the right polarity, we set the
"override_active_level" to false in mmc_gpiod_request_cd()
and mmc_gpiod_request_ro().

Linus Walleij efdfeb079c
regulator: fixed: Convert to use GPIO descriptor only
As we augmented the regulator core to accept a GPIO descriptor instead
of a GPIO number, we can augment the fixed GPIO regulator to look up
and pass that descriptor directly from device tree or board GPIO
descriptor look up tables.

Some boards just auto-enumerate their fixed regulator platform devices
and I have assumed they get names like "fixed-regulator.0" but it's
pretty hard to guess this. I need some testing from board maintainers to
be sure. Other boards are straight forward, using just plain
"fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the
device ID.

It seems the da9055 and da9211 has never got around to actually passing
any enable gpio into its platform data (not the in-tree code anyway) so we
can just decide to simply pass a descriptor instead.

The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named
"*_dummy_supply_device" while it is a very real device backed by a GPIO
line. There is nothing dummy about it at all, so I renamed it with the
infix *_regulator_* as part of this patch set.
