Legacy platform_data removal for omaps for v4.10 merge window.
We've dropped the last legacy boot board-*.c files for mach-omap2
for v4.9 so now we can start removing the unused platform_data.
All of the below has been unused since v4.9 merge window:
- Drop legacy pmic init code
- Apply seq_puts() fixes for legacy mux code, then drop it
- Drop legacy serial init
- Drop legacy i2c init
- Drop legacy PM init
- Drop legacy twl4030 platform init
- Drop legacy USB host init
- Drop legacy muxing for tusb6010, n8x0 is still using it's
platform init via pdata-quirks.c
- Drop legacy musb init
- Drop hwmod related legacy mux code
- Drop legacy hwmod data for omap3
- Drop legacy smsc911x and smc91x init
- Drop legacy board flash init
- Drop legacy ads7846 init
- Drop legacy sdram timings

All the boards booting with device tree use
drivers/pinctrl-single.c instead.
Note that mach-omap1 is still using the legacy mux,
so let's move the related Kconfig options from plat-omap
to mach-omap1.

We need to properly initialize mpuss also on omap5 like we do on omap4.
Otherwise we run into similar kexec problems like we had on omap4 when
trying to kexec from a kernel with PM initialized.

Kexec booted kernels on omap4 will hang early during the boot if the
booted kernel is different version from the previous kernel.
This is because the previous kernel may have configured low-power mode
using CPU1_WAKEUP_NS_PA_ADDR. In that case it points to the previous
kernel's omap4_secondary_startup(), and CPU1 can be in low power mode
from the previous kernel. When the new kernel configures the CPU1
clockdomain, CPU1 can wake from low power state prematurely during
omap44xx_clockdomains_init() running random code.
Let's fix the issue by configuring CPU1_WAKEUP_NS_PA_ADDR before we
call omap44xx_clockdomains_init(). Note that this is very early during
the init, and we will do proper CPU1 reset during SMP init a bit later
on in omap4_smp_prepare_cpus(). And we need to do this when SMP is
not enabled as the previous kernel may have had it enabled.

Prepare things for making kexec work on SMP omap variants by initializing
SARM RAM base early. This allows us to configure CPU1 for kexec in case
the previous kernel has put CPU1 in low power mode.
Note that this should not prevent moving other SAR RAM code to live
under drivers. However for kexec, we will need this very early.

Merge "omap fixes against v4.6-rc2" from Tony Lindgren
Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.
It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.
Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.
Also included is a fix for dra7 sys_32k_ck clock source that is not
enabled on boot making system fall back to using emulated clock.

When commit 06c2d368fc36 ("ARM: OMAP: DRA7: Make use of omap_revision
information for soc_is* calls") introduced SoC check using
omap_revision, it missed providing DRA7 as class for initializing
the omap_version variable. Without doing this, soc_is_dra7xx() will
fail and as a result, omap4_pm_init_early never initializes the dra7
erratum for CPU power state. This causes the suspend path to fail
on DRA7 devices.

commit f746929ffdc8 ("Revert "ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688"")
and
commit ea827ad5ffbb ("ARM: DRA7: Provide proper IO map table")
came in around the same time, unfortunately this seem to have missed
initializing the barrier for DRA7 platforms - omap5_map_io was reused
for dra7 till it was split out by the last patch. barrier_init
needs to be hence carried forward as it is valid for DRA7 family of
processors as they are for OMAP5.

We actually need this code for proper behaviour of OMAP4, and it needs
fixing a different way other than just removing the code. Disabling
code which is necessary in the hopes of persuing multiplatform kernels
is a stupid approach.

The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a
contradiction in it's dependencies.
The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an
enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be
enabled. These options inherit a dependency from an enclosing menu,
that requires ARCH_MULTIPLATFORM to be 'enabled'.
This is a contradiction and made this option also unavailable for
non-multiplatform configurations.
Since there are no selects on OMAP4_ERRATA_I688, which would ignore
dependencies, the code related to that option is dead and can be
removed.
This (logical) defect has been found with the undertaker tool.

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

Otherwise it will return true for cpu_is_omap34xx() which we don't
want for the clocks and hwmod. It's closer to am33xx for the clocks
and hwmod than to the omap34xx. We also want to be able to detect
814x and 816x separately as at least the clocks are different with
814x using a apll and 816x using a fapll for the source clocks.
Note that we can also remove omap3xxx_clk_init() call as it's wrong
and ti81xx are booting in device tree only mode.

Pull clock tree updates from Mike Turquette:
"The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers.
This tag contains a bit more arch code than I usually take due to some
OMAP2+ changes. Additionally it contains the restart notifier
handlers which are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree
I had to revert one patch and follow up with one more fix near the tip
of this tag. Some dead code is introduced but it will soon become
live code after 3.18-rc1 is released as the rest of the PXA family is
converted over to the common clock framework.
Another trend in this tag is that multiple vendors have started to
push the complexity of changing their CPU frequency into the clock
driver, whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to
some confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems."

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.
