Given that we want the default to not have any <mach/memory.h> and given
that there are now fewer cases where it is still provided than the cases
where it is not at this point, this makes sense to invert the logic and
just identify the exception cases.
The word "need" instead of "have" was chosen to construct the config
symbol so not to suggest that having a mach/memory.h file is actually
a feature that one should aim for.

This generalizes the omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src
implementation between generic McBSP and OMAP2 specific McBSP code. These
functions are used to select source for CLKR and FSR signals on OMAP2+.
Start generalizing the code by implementing an optional mux_signal function
pointer in platform data that will implement the actual muxing and which is
called now from omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src.
These functions are to be removed later and cleanup the API so that
mux_signal gets its arguments directly from client code.

This generalizes the omap2_mcbsp_set_clks_src implementation between generic
McBSP and OMAP2 specific McBSP code. Currently this function is used to
select either internal fclk or clks pin as a McBSP CLKS source on OMAP2+.
Implement generalization by having an optional set_clk_src function pointer
in platform data that is used to select parent for a given clock. Idea is to
pass higher level source clock name (later coming from client driver) that
platform specific code will map to platform specific clock name.
API cleanup between McBSP and client code comes later.

Sidetone resource is already registered for a device so there is no need
for cpu_is_omap34xx() and McBSP port number tests in the driver. We can
cleanup and make the code generic by dropping remaining CONFIG_ARCH_OMAP3
conditional compilations and then using sidetone resource and st_data
variable for runtime tests.

Active sidetone requires that McBSP interface clock doesn't idle and there
is no mechanism in hwmod to turn autoidling on/off in runtime. McBSP2 and 3
in OMAP34xx share their interface clock with McBSP sidetone module and
that interface clock must be active when the sidetone is operating.
Sidetone has its own autoidle bit which should keep the interface clock
active but it is broken. Putting the McBSP core to no-idle mode when the
sidetone is active is no good either since it results to higher power
consumption when using the threshold based DMA transfers.
For making the McBSP code more generic, move this sidetone clock management
with fixme comments to mach-omap2/mcbsp.c and pass pointer to it via
platform data.

Remove CONFIG_ARCH_OMAP3 conditional compilation and cpu_is_omap34xx test
around buffer threshold based transfer and DMA operating mode control. Use
instead the buffer_size in platform data to determine when these sysfs
controls are exposed and when to access related McBSP registers. Rationale
for this is to make code generic and to allow to use it on OMAP4 that also
supports threshold based transfers.
Currently buffer_size variable is set only for OMAP3 SoCs but it is easy
to extend to OMAP4 and any later OMAP version.

Currently wakeup control code is compiled only when CONFIG_ARCH_OMAP3 is
set even it should be available for CONFIG_ARCH_OMAP4 only builds also.
Fix this by making wakeup control generic so that it is executed whenever
new feature flag has_wakeup in platform data is set. Currently flag is set
for McBSP config types 3 and 4.
Remove also old comments about idle mode settings and HW bug workarounds
that were not updated during hwmod conversion.

Register access can be made more generic by calculating register address
offsets runtime from common register definitions and by using reg_size and
reg_step variables that are passed via platform data. Common register
definitions are possible since McBSP registers are ordered similarly between
OMAP versions.
Remove also references to OMAP2+ specific config_type variable from generic
McBSP code since other variables and feature flags are better to carry needed
information from platform code.

Rather than embedding a struct platform_device inside a struct
omap_device, decouple them, leaving only a pointer to the
platform_device inside the omap_device.

All of the device init and device driver interaction with omap_device
is done using platform_device pointers. To make this more explicit,
have omap_device return a platform_device pointer instead of an
omap_device pointer.
All current users of the omap_device pointer were only using it to get
at the platform_device pointer or struct device pointer, so fixing all
of the users was trivial.
This also makes it more difficult for device init code to directly
access members of struct omap_device, and allows for easier changing
of omap_device internals.

For consistency in kernel printk output for devices, use dev_dbg(),
dev_warn(), dev_err() instead of pr_debug(), pr_warning() and
pr_err(), some of which currently use direct access of name from
platform_device and others of which use dev_name(). Using the dev_*
versions uses the standard device naming from the driver core.
Some pr_* prints were not converted with this patch since they are
used before the platform_device and struct device are created so
neither the dev_* prints or dev_name() is valid.

The OMAP3505/AM3505 appears to be based on the same silicon as the

part of the OMAP3517/AM3517 family.

Remove the old OMAP35XX_CLASS, which actually covered two very different
chip families. The OMAP3503/3515/3525/3530 chips will now be covered by
OMAP343X_CLASS, since the silicon appears to be identical. For the
OMAP3517/AM3517 family, create a new class, OMAP3517_CLASS.

Commit c03f007a8bf0e092caeb6856a5c8a850df10b974 (OMAP: PM:
omap_device: add system PM methods for PM domain handling) mistakenly
used SET_SYSTEM_SLEEP_PM_OPS() when trying to configure custom methods
for the PM domains noirq methods. Fix that by setting only the
suspend_noirq and resume_noirq methods with custom versions.
Note that all other PM domain methods (including the "normal"
suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS,
which configures them all to the default subsystem (platform_bus)
methods.

There's no need to call omap2_init_common_devices from init_early.
It no longer does anything else except reprogram the memory timings

Move it to happen after omap_serial_init gets called. And while

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead. This means that by default, you get the trivial implementation
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.
