We can now probe devices with ti-sysc interconnect driver and dts data.
Let's drop the related platform data and custom ti,hwmods dts property.
As we're just dropping data, and the early platform data init is based on
the custom ti,hwmods property, we want to drop both the platform data and
ti,hwmods property in a single patch.

When I dropped legacy data for omap4 and dra7 smartreflex in favor of
device tree based data, it seems I only testd for the "SmartReflex Class3
initialized" line in dmesg. I missed the fact that there is also
omap_devinit_smartreflex() that happens later, and now it produces an
error on boot for "No Voltage table for the corresponding vdd. Cannot
create debugfs entries for n-values".
This happens as we no longer have the smartreflex instance legacy data,
and have not yet moved completely to device tree based booting for the
driver. Let's fix the issue by changing the smartreflex init to use names.
This should all eventually go away in favor of doing the init in the
driver based on devicetree compatible value.
Note that dra7xx_init_early() is not calling any voltage domain init like
omap54xx_voltagedomains_init(), or a dra7 specific voltagedomains init.
This means that on dra7 smartreflex is still not fully initialized, and
also seems to be missing the related devicetree nodes.

After converting am335x to probe devices with simple-pm-bus I noticed
that we are not passing auxdata for of_platform_populate() like we do
with simple-bus.
While device tree using SoCs should no longer need platform data, there
are still quite a few drivers that still need it as can be seen with
git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a
replacement for simple-bus also for cases where OF_DEV_AUXDATA is still
needed.
Let's fix the issue by passing auxdata as platform data to simple-pm-bus.
That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA.
And let's pass the auxdata for omaps to fix the issue for am335x.
As an alternative solution, adding simple-pm-bus handling directly to
drivers/of/platform.c was considered, but we would still need simple-pm-bus
device driver. So passing auxdata as platform data seems like the simplest
solution.

We now depend on SIMPLE_PM_BUS for probing devices. While we have it
selected in omap2plus_defconfig, custom configs can fail if it's missing.
As SIMPLE_PM_BUS depends on OF and PM, we must now select PM in Kconfig.
We have already OF selected by ARCH_MULTIPLATFORM.
Let's also drop the earlier PM dependency entries as suggested by
Geert Uytterhoeven <geert@linux-m68k.org>.

We get suspcious RCU usage splats with cpuidle in several places in
omap_enter_idle_coupled() with the kernel debug options enabled:
RCU used illegally from extended quiescent state!
...
(_raw_spin_lock_irqsave)
(omap_enter_idle_coupled+0x17c/0x2d8)
(omap_enter_idle_coupled)
(cpuidle_enter_state)
(cpuidle_enter_state_coupled)
(cpuidle_enter)
Let's use RCU_NONIDLE to suppress these splats. Things got changed around
with commit 1098582a0f6c ("sched,idle,rcu: Push rcu_idle deeper into the
idle path") that started triggering these warnings.
For the tick_broadcast related calls, ideally we'd just switch over to
using CPUIDLE_FLAG_TIMER_STOP for omap_enter_idle_coupled() to have the
generic cpuidle code handle the tick_broadcast related calls for us and
then just drop the tick_broadcast calls here.
But we're currently missing the call in the common cpuidle code for
tick_broadcast_enable() that CPU1 hotplug needs as described in earlier
commit 50d6b3cf9403 ("ARM: OMAP2+: fix lack of timer interrupts on CPU1
after hotplug").

ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence of struct page associated with a pfn when there are holes
in the memory map.
However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.
The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.
Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.

On the GTA04A5 od->_driver_status was not set to BUS_NOTIFY_BIND_DRIVER
during probe of the second mmc used for wifi. Therefore
omap_device_late_idle idled the device during probing causing oopses when
accessing the registers.
It was not set because od->_state was set to OMAP_DEVICE_STATE_IDLE
in the notifier callback. Therefore set od->_driver_status also in that
case.
This came apparent after commit 21b2cec61c04 ("mmc: Set

oops:

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

To drop the legacy platform data for am3 control module, we need
to configure the missing functional clock and tag the module to
not idle as platform data also had it configured with
HWMOD_INIT_NO_IDLE.

In preparation for probing the interconnects with simple-pm-bus to
make use of genpd, we need to probe the always-on PRCM first for the
clocks needed by l4_wkup instance.

If we have no hwmods configured and omap_hwmod_init() is not called,
we don't want to call omap_hwmod_setup_all() as it will fail with
checks for configured MPU at least.

Based on more testing, commit 8ca5ee624b4c ("ARM: OMAP2+: Restore MPU
power domain if cpu_cluster_pm_enter() fails") is a poor fix for handling
cpu_cluster_pm_enter() returned errors.
We should not override the cpuidle states with a hardcoded PWRDM_POWER_ON
value. Instead, we should use a configured idle state that does not cause
the context to be lost. Otherwise we end up configuring a potentially
improper state for the MPUSS. We also want to update the returned state
index for the selected state.
Let's just select the highest power idle state C1 to ensure no context
loss is allowed on cpu_cluster_pm_enter() errors. With these changes we
can now unconditionally call omap4_enter_lowpower() for WFI like we did
earlier before commit 55be2f50336f ("ARM: OMAP2+: Handle errors for
cpu_pm"). And we can return the selected state index.

We should select also PM_GENERIC_DOMAINS_OF in addition to
PM_GENERIC_DOMAINS to have device tree based PM domain providers
enabled.

I accidentally misplaced select PM_GENERIC_DOMAINS, it should be
selected for all the SoCs instead.
